I was a bit hesitant to see a new psychiatrist and after reading some reviews, I expected a quick and sterile interaction. I came in with my list of questions in case I got flustered or felt rushed, but Dr. Deirmenjian greeted me warmly and was immediately interested in what we hoped to accomplish together. He took thorough notes and gave an incredibly detailed description of my options before making his recommendations and taking my thoughts into account. I look forward to continuing to work with him on this journey! read more

Dr. Deirmenjian has been one of the best psychiatrists I have seen in my 40 years of needing this specialty care. He works with me on medication management and looking at alternative treatments for my mental health, carefully listening to my history and current needs. He considers my physical health and insurance coverage as part of his practical and compassionate approach, and he is consistent as well as flexible with his availability. His staff have been outstanding and professional in helping with insurance changes and appointment arrangements. I appreciate that Dr. Deirmenjian follows up on medications he prescribes immediately following an appointment, and I have not had a pharmacy problem ever with his prescriptions! I would highly recommend him! read more

I had a great experience with TMS and the results of my treatment. The technicians I worked with at both the Beverly Hills and Glendale Offices were both very friendly and welcoming and easy to talk with during my treatments. The TMS technicians were also very flexible with scheduling my appointments and my appointments were always right on time and done quickly. I really enjoyed being able to talk to the technicians during my treatment and it made the time fly by. I have already benefited from the results and would definitely recommend treatment with Dr. Deirmenjian. Prior treatments I have tried were not effective. The office staff were very friendly and welcoming, too. read more

I've been seeing Dr. Deirmenjian for a few months now, and he's been a real blessing. After struggling with meds and dealing with less-than-great doctors, he's been so patient and kind, working with me to find something that'll get my world under control. His staff is super sweet and helpful too. If you need a caring doctor, Dr. Dermajian's your guy read more

Dr. Deirmenjian and his entire Glendale staff foster an environment full of compassion and empathy. I can always count on appointments being readily available with the flexibility and follow up that a working adult needs. I enjoy seeing the diverse faces in the office waiting room. Different races, ethnicities, ages, and walks of life. The personalized care I get from Dr. Deirmenjian is unmatched which is why I have remained a patient for over half a decade. TMS has been a game changer and has contributed to a drastic improvement in my quality of life. The TMS tech, Amy, is an amazing indispensable part of the team. read more

Very kind attentive staff. They take insurance. Parking is free for first 90 minutes. My treatment for anxiety was non-invasive and had no side effects. read more

He is a terrible doctor, and in my opinion dangerous. I found out the hard way when my medication stopped working and was given zero options to improve my condition, just a callus "yeah that happens". Not to mention the office staff is completely rude. Well here's what actually happened after working with a different, caring psychiatrist... I am on less medication than before and doing fantastic! We are addressing root causes of anxiety and they actually took the time to get to know me and my medical history. There are amazing, caring, professional psychiatrists out there and this guy is not one of them. Avoid, avoid, avoid at ALL costs if you want to actually improve your life. read more

Caring doctor, deep experience, knowledgable in many areas and very responsive. There is one woman in his office that is rude and awful on the phone, but don't let her throw you off (and hopefully you get one of the nice ones when you call), once you get to the doctor, you'll be in extremely capable, caring hands! read more

I just completed my 36 sessions of TMS (transcranial magnetic stimulation) to help with my mild-moderate situational depression and I am SO grateful to Dr. Dermenjian and his assistant, Lucia! Ive started loving music again, finding excitement and joy in the little things like I used to, feel empowered/capable/strong and hopeful for good things to come. I have more energy and joy when I am with my toddler, have connected again more deeply with friends and family, enjoying peaceful moments to myself and figuring out self-love/self-care again. I found Dr. Dermenjian a few months ago (thru Neurostar, I wanted to find a Dr/office that has done TMS for a while and takes my insurance), as I have been seeking to navigate some complicated life circumstances, and wanted to improve how I feel once and for all. I have struggled with chronic pain and immense situational depression for years. Since the first day I spoke with him, I immediately felt at ease with his kindness, professionalism, intelligence and incredibly calm voice and demeanor. I feel a SIGNIFICANT improvement, as I have completed 36 seventeen-minute sessions of TMS. The tapping itself was not what I would call comfortable, but was NOTHING in order for me to start feeling like myself again! I am starting to feel better than I have felt mentally in years, and truly feel that the sky is the limit for me (like I did years ago). I am so blessed to have Dr. Dermenjian to keep up with, as needed, in order to create calm, health and freedom within my own nervous system again. I truly appreciated when he would check in on me and make himself available whenever I needed to talk. His kindness and empathy, along with his MANY diplomas/accolades, will always be appreciated and remembered by me. I would also like to focus attention on his wonderful assistant, Lucia, who was there for me and setup every session! My part-time work schedule posed some challenges, but she so kindly accommodated my schedule, so we could complete the 6 weeks without interruption and so I wouldn't have to take off work (I love what I do and couldn't financially afford to take off work). I truly valued her super sweet personality and kindness every time I would see her. She is applying for medical school and would be an incredible asset to the medical field! Thank you again to Dr. Dermenjian and Lucia, for their incredible efforts to bring me back to *feeling* and *loving* my life again. I am getting teary eyed as a write this and will be forever thankful to have found them. I feel relieved and elated to have Dr. Dermenjian in my corner! Thank you deeply! read more

I have seen Dr. Deirmenjian for a couple of years at this point, and I can honestly say he has changed the trajectory of my life in a positive way. I first met Dr. Deirmenjian as someone very skeptical of psychiatry in general. He shattered all my negative preconceptions of the profession. He is warm and caring. He is genuinely interested in my well being and overall success as a person. In times of crisis, he has made himself available to me to the extent that I needed. After many years of treatment-resistant depression, it was Dr. Deirmenjian who got me on the right medication and dosage that works for me. There are some negative reviews here that seem to all focus on his office staff. Maybe they aren't aware of the high turnover and difficulty in hiring and keeping competent staff. Most of the negative reviews actually appear to be written by people who never even became patients, and they are just people who may or may not have called his office one time. Many of them understand HIPPA compliance about as well as Marjorie Taylor Greene, which is to say - not at all. I personally have never experienced any issues with intake, scheduling, or prescription refills or changes. Staff in his office and on the phone have always been respectful and accommodating. I have always been able to get an appointment with the doctor when I needed one, and Dr. Deirmenjian made himself available to his patients even during the height of the pandemic. Choosing a doctor is an individual choice and an important one. Everyone is different and has different needs. But if you want a well informed and compassionate psychiatrist then make an appointment with Dr. Deirmenjian. Decide for yourself if it is the best fit for you. It definitely was for me. read more

Very good doctor listens very well and I am very happy to hear that you are doing well and very honest

The doctor's receptionist said the doctor was accepting new patients--until I said that one of my symptoms was ADHD. "He's not prescribing those medications," the receptionist said (though I didn't mention wanting any medications). So, the first wrong thing here is that he clearly lists "ADHD" as one of his SPECIALTIES if you look at his listing under your health insurance plans. The only reason I called him is for the thing he now refuses to see me for. The second thing wrong here is that I have a lot of other co-morbid conditions. Should having ADHD mean that the doctor can't treat me for depression? And third of all, not all ADHD people take "those" medications. I don't actually think there's anything wrong with being prescribed "those" medications, but even so, why not accept ADHD patients as long as they agree that they will seek out alternative treatments, if that's a deal-breaker for you? Fourth of all, dude, I'm sorry if you have seen some drug-addict patients in the past that annoyed you, but that doesn't change the fact that ADHD is a real thing, and for many of us, it's more debilitating than what many junkies go through. And yes, it's very true that some ADHD drugs are addictive, or can be harmful if taken incorrectly. It's also true that they can work really well for the people who need them, and that the vast majority of ADHD experts see them as being a crucial first step in helping combat the symptoms of ADHD for many people. It's also true that not all the ADHD medications are things like Adderal or Ritalin--there are also serotonin boosting medications that can help some ADHD patients, or long-term drugs such as Vyvanse that have no addictive properties. Most ADHD patients have a hard enough time trying to make a go of it, medications or no, along with counseling, therapy, and a life of hard work. I've been trying to get myself to even get on the phone and call psychiatrists ever since mine died, and one of the difficulties is the shade thrown on people like me by people like you... you know, the supposed protectors of emotional wellness. Thanks for making it that much harder. read more

Dr. Deirmenjian has been my psychiatrist since I moved to CA in 2007. I was an absolute mess but he never gave up on me and I'm truly grateful. We worked together on a treatment plan which has always been a combination of therapy, medication adjustments and most recently, TMS. If you expect Dr, Deirmenjian to talk with you for hours at a time, then find another psychiatrist because he's not the right physician for you. As I talk with him, Dr. Deirmenjian is typing but he is also observing my mood and other behaviors that I may exhibit during a session. Lastly, I appreciate Dr, Deirmenjian being sensitive to me as an LBGTQ patient. read more

Why does he have 2 yelps?! This score being SLIGHTLY better. Hiding behind this one DR. D? You are THE MOST IRRESPONSIBLE PSYCHIATRIC PHYSICIAN I HAVE EVER DEALT WITH. I came to you in crisis after being a long time patient and you SCREAMED at me BY NAME in your lobby that you weren't "running a charity!!" Because you had recently become out of network with my insurance and you wanted hundreds of dollars before you'd help me, again I was IN CRISIS. That's why I reported you to the board and even if nothing happens it's my personal mission to warn others. Your receptionist was so unkind and disrespectful too. DO NOT SEE THIS DOCTOR IF YOU WANT ACTUAL HELP. IF YOU JUST WANT TO PAY FOR PILLS HE'S YOUR GUY. read more

Dr Deirmenjian is a very kind soul. He started me on a treatment of TMS which I needed. I later developed a severe health problem unrelated and he offered to be my advocate to get a hold of my PCP. No one has ever done or offered to do such a thing for me before, not even my family! He has shown me only kindness and compassion, and when I needed him, he called me and spoke with me for a good 20 minutes offering his assistance to an unrelated problem. I drive down extra far to the Long Beach office because I love the nurse practitioner named Colleen. She is very kind and caring during my treatments. Jannette is kind now too. I really recommend this doctor and the Long Beach branch of it, being treated by Colleen. and Dr Deirmenjian. I am grateful when I am able to find a good doctor, and I am especially grateful for Colleen and this doctor and feel that I am in good hands now. read more

I know it is a busy time for mental health providers, and I understand that as an assistant to a psychiatrist, the person answering the phone may have some challenging callers. But this doctor needs to train his assistant in the dangers of violating confidentiality and HIPAA. I want the doctor to know that when I called his office, his assistant insisted on knowing my possible diagnosis, which is a violation of my confidentiality, and which, obviously is non of her business. When I refused to answer, she became immediately combative. She was utterly unprofessional and inappropriate. I could understand this if she worked at a fast food restaurant, but a receptionist at a psychiatrist's office should expect human beings to be calling her in distress during COVID, and she should be calm and collected, no matter how callers behave. She is there to answer questions, not to demand answers to them. She was, quite frankly, cold and rude to me. I was so shocked that she would ask such a personal question that I am afraid I was short with her, but she is not appropriate for her job. She basically drove me away. If any mental health provider would prefer that his assistant be combative, that is truly monstrous during these stressful times. She needs to be retrained to be sensitive, or let go. No one should call this doctor if they are in emotional distress or needs help. My suggestion is that instead of hiring an inappropriate gatekeeper unversed in doctor-patient confidentiality, he hire someone to set up a website where patients can contact him in a leisurely fashion. Do not call this provider if you actually need help regarding emotional distress. Don't, for your own good. read more

I been seeing Dr Deirmenjian for about 15 years and have never had any issue with his treatment choices or suggestions for me. Fee is fair and affordable, appointments are focused and Dr D has always been there for me after one of my extended vacations from receiving care. read more

I'm very grateful to find Dr. Deirmenjian. He's kind, listens and gives you the attention you deserve. Finding a compassionate Doctor who responds in a time of need is a god send. If you need a competent and understanding Doctor, look no further! :) read more

This review is a year late as I came to Dr. D after experiencing a lack of compassion and trust in Socal TMS--I was willing to drive to him daily instead of walk 5 minutes to SoCal TMS. It hit me today that it has been a year since working with Dr. D and Amy for TMS, and I'm so grateful. I have struggled with depression my entire life, and their compassion and persistence has helped me feel free of suicidal ideation for an entire year. Thank you read more

Dr. Deirmenjian has been a steadfast source of encouragement and support for me through some very difficult times in these past few years. Without his guidance, I would not be the person I am today. The path to mental wellness is not easy, but it is so much less intimidating with Dr. Deirmenjian in my corner. read more

Dr.Diermenjian is a wonderful psychiatrist! I have been seeing him for years now. He truly cares about you, as the client, and wants to help. He was able to find the correct meds for me and help me immensely. I absolutely recommended him! read more

Totally bizarre "intake" process of the receptionist demanding I state my specific diagnosis by phone before making an appointment. They were really pushy about it. Doesn't feel HIPAA compliant. read more

The pros: you can always get an appointment The cons: wow, I have never met a psychiatrist that listens less. I have two prescriptions - one for emergencies only that I haven't taken in a while. He never seems to understand that and it took 3 appointments for him not to renew a prescription I use maybe 4x a year and now have a stockpile of. In addition, if you use ExpressScripts, do not trust that the office will fax the prescription. I waited a week for my medication to arrive and nearly ran out before calling ExpressScripts. They hadn't received the prescription at all. While this could be a simple mistake, the office staff must have lost the prescription. While they gave me 5 days worth of meds I could pick up from CVS, the dosage was wrong - in my most recent appointment we changed my dosage. When I finally got my meds from ExpressScripts, it was the incorrect (old) dosage as well. Either way, I can't get what I need from them and can't wait for my new insurance and to find an new psychiatrist. read more

Dr. D is beyond an amazing doctor and is an even better person! He is kind, patient, attentive and deeply knowledgable. Above all, he has compassion. He is an excellent listener and takes his time to figure out what is working and what isn't. I feel blessed to have found him. Couldn't recommend higher. read more

I saw Dr. Dermenjian several years ago and after about 2 months of treatment filed a complaint against him with my insurance provider. My visits were exactly 5 minutes each time, but he was billing my insurance for 20 minute sessions. What a crook!! When I asked follow up questions beyond 5 minutes, I was shooed out of his office. At the time I was struggling with severely crippling depression and suicidality along with many other extenuating circumstances and untreated conditions beyond that, and it takes more than 5 minutes to describe what I was struggling with. In a period of about 2 months I was cross tapered between 3 different psych meds, one of which I was given a coupon for to get a free trial (obviously given to him by a pharmaceutical rep). I was so emotionally unstable at the time that this created severe chaos in my life. How can I trust a doctor to have my best interest at heart when he's feeding me pills that he's getting kickbacks for from big pharma?? Another time, I called to have my prescription refilled, and his assistant called in the script with the same medication but a different form that gave me debilitating panic attacks for an entire day. Unacceptable!!! If you have an appointment with this guy, do yourself a favor and find someone else. ANYONE else. Treatment with this doctor was the worst psychiatric experience of my life. read more

Dr​ John is absolutely​ very professional and flexible​ and he will give you what you need. Even though I am no longer close to his office but I still make a long drive to visit him. read more

Excellent doctor and very considerate and passionate about his patients. He is always available for his patients and easy to get an appointment. His staff is amazing and very helpful. I am glad he is my doctor taking care of my medical condition. read more

Am I actually writing a yelp review on a doctor? Yes, yes I am. And the reason why is because I don't think he deserves these negative reviews. I live in the valley and getting to him isn't the easiest but after seeing him for 3 months it's worth it. He does have an office in Glendale which makes more sense for me to go to but his hours on Wilshire work best for me. On my first visit I was a bit intimidated based on his reviews but as soon as we started speaking it all went away. My first appointment was about 30 minutes long. He was getting my physical and mental history, wanted to know why I was there and what I wanted out of seeing him. He was (and always is) super polite, attentive and I've never felt rushed. Plus he was super sympathetic to things that my female PCP was totally aloof about which made me feel like I wasn't sooooo crazy. Just you know, a little bit! He's a psychiatrist, not a therapist. His appointments aren't meant to last 55 minutes. 10-15 is the norm if everything is going well and he always asks how things are going overall as well as how the medication is working for me to see if he needs to make any adjustments. I think he's great, his staff is always polite over the phone and in person and the office on Wilshire is immaculate. read more

I had the great good fortune to have been referred to Dr. Deirmenjian nearly five years ago when my health was in very poor shape. As a result of Dr. Deirmenjian's poignant questions and resultant prescriptions I am no longer on Disability and am now able to do fulltime volunteer work for a national organization. I have never once felt rushed by Dr. Deirmenjian. In fact, to the contrary, he has never discouraged a little extra time with him. His demeanor is no non-sense and to the point, and his prescription methodology, I can attest, works. If you are seeking excellence in a physician, look no further than Dr. Deirmenjian. read more

Out of all physicians, psychiatrists are supposed to be the most caring. But Dr. Deirmenjian is the least caring psychiatrist ever. He avoids making eyecontact, he gets angey if a patient is late to their appointment, and he is always, always more than happy to send a patient to another psychiatrist, as opposed to trying to work with them to improve their mental/psychological health. I'd honestly stay away from him. He is awful. read more

I have been a patient for Dr. Deirmenjian for the past 10 years. He has always been an exceptional doctor throughout, but especially during these challenging pandemic times. He was completely available for my appointments on the phone, gave me excellent advice like always, and kept me on track. In addition, his staff is exceptionally personable and are always available to assist if I have any scheduling issues or questions. I highly recommend him to anyone seeking an experienced, knowledgeable and professional psychiatrist. read more

He is not a caring or concerned physician. over the 5 years he has been treating me for severe psychiatric issues he has not been invested in my over all health. I have had to take matters into my own hands and be hospitalized 3 times each time a week for medication changes!! We've parted ways and I do not recommend him to anyone. read more

I think the prior reviews are confusing psychiatrist with psychologist. He is a 5-star psychiatrist, and he is not supposed to serve in a psychologist's capacity. Psychologists sit with you for a hour, explore how you feel, and advise you how to cope (Cognitive Behavioral Therapy, etc etc). Psychiatrists communicate with psychologists, analyze the data provided, and confirm the info with the client. At that point, if it is felt medicine is necessary, he will prescribe based on his evaluation, which takes 5-15min. Psychologists counsel and cannot prescribe. Psychiatrists prescribe, with limited counsel; enough to make sure everything is on course. He's one of the best in the biz, as long as you understand the difference. read more

I saw Dr. Deirmenjian for a few years and ultimately become very unhappy with his treatment. When I first started seeing him I was in a depressive episode so severe I could barely get out of bed. A friend actually took me to the appointment. The depression improved slightly over time with medication, but not significantly. Dr. Deirmenjian uses a lot of TMS, Transcranial Magnetic Stimulation, in his practice. As my depression proved to be somewhat medication resistant, he felt TMS was the solution. For most people the treatment is painless and the side effects are minimal. Unfortunately, I am not like most patients. The treatment itself was incredibly painful and caused a huge increase in my pain and fatigue, as well as triggering daily migraines and serious bouts of nausea. The depression improved slightly but not enough for my insurance to continue paying for the TMS. The minimal improvement didn't last and my insurance agreed to a second round, which was ineffective. Dr. Deirmenjian's solution was to put me on increasingly higher doses of multiple medications. My average appointment with him lasted approximately 3-5 minutes and consisted of him asking me what medications I was taking and what the dosages were. Most of the time he would forget what I was on and tell me to make changes we had already made. For some reason he didn't consult my chart, but I suppose that makes sense considering he only met with me for a few minutes. At one point Dr. Deirmenjian put me on a medication that can have a very dangerous side effect in a small percentage of the population. When I began to have these symptoms I called him multiple times to ask if I could stop taking it. He never responded. Family and friends expressed great concern that the depression was worsening and consistently told me I seemed like a "zombie". They were concerned I wasn't receiving appropriate treatment. They tried to convince me to see someone else. I was aware I was receiving a low level of care and that it wasn't working but was too depressed and drugged to make a change. My father spoke with Dr. Dermeinjian, asking about other possible treatment options but Dr. Deirmenjian kept telling him it was medications or TMS, which we already knew didn't work for me. Eventually my father took me to see another psychiatrist who got me into a partial hospitalization program. While I was in the program I worked with one of their psychiatrists who immediately began changing my medication regimen. He said I felt and acted like a zombie because I was over-medicated. Sure enough, as I titrated off certain medications the zombineness dissipated. He cut down on the number of medications I was on and lowered the dosage of others, while adding some new ones. This, along with the intensive treatment program was very helpful. I improved and some of the depression abated. By the time I left the program I was healthy enough to care about the quality of my psychiatric treatment and was horrified by how long I allowed myself to stay with Dr. Deirmenjian. I found a psychiatrist who meets with me far longer than 5 minutes, actually checks in with me to monitor my progress, adjusts my medications as necessary, returns my phone calls, and does his best to minimize the number and dosages of medications I am on. He also provides additional resources when I'm not doing as well, such as referring me to group therapy. Finding such a great doctor makes me feel badly for those who are settling for the kind of narrow scope and poor quality of care I received from Dr. Deirmenjian. Several months after I stopped treatment with him, I needed some medical records and paperwork from him. It took months to get it and he refused to take care of it until I met with him several times, during each of which he was supposed to give me the records. I finally asked a friend for assistance and she went to his office several times before finally collecting it. I have seen many medical doctors over the years and find it worrisome that patients are falling prey to these types of lackadaisical practices, especially in the mental health field. read more

Not sure why all the bad stars. I found him to be very caring and helpful. Didn't suggest anything I didn't need and fit me in to his busy schedule when I had to see him before leaving for a long trip. read more

I like him! He is straight and to the point. Just what I was looking for. Appointments are quick, so if you need an hour of pouring over your deepest thoughts, a psychologist or therapist is the way to go. read more

Never had problems with him in the years I've been going to him. Very friendly and always very helpful. Yes appointments are not very long, but they shouldn't be, he's a Psychiatrist, not a Psychologist. Something another reviewer needs to keep in mind. read more

This review is way overdue. It seems a bit weird to review a doctor on yelp (especially a psychiatrist), but I think he deserves the recognition. I'm pretty sure he saved my life. I have been a patient of Dr. Deirmenjian for over two years, and he is perhaps one of the finest medical professionals I have ever encountered (and I've had several). Why? Because he cares, he's compassionate, and I know that he has my best interest in mind. I trust him. Other psychiatrists have tried to just send me off with a prescription for something I have told them gives me horrible side effects, but Dr. D actually listened and offered other options that seriously changed my life for the better. His office staff is rock solid as well and was able to get 40+ sessions of TMS approved for one $30 copay (YMMV). Let me put it this way: I live in San Diego; when he had to close his Temecula office and his nearest location turned out to be Long Beach, I stuck with him because I trust him and don't want to risk starting over with someone I don't know. I drive two hours to Long Beach to see him, and it's worth it. Thank you Dr. Deirmenjian. read more
