I felt seen and heard by Dr. O'Connor. I'm grateful for her medical guidance and look forward to getting my health back on track. I trust in the wisdom of her plan. read more

So far in my opinion an amazing doctor who really tries to figure out what's going on.

Dr O'Conner is absolutely amazing! She was very helpful in helping to transform my Diabetes 2 to becoming normal again. The reward? Learning how to protect the heart and overall health. She is from the UK, and if you ask she will delightfully guide you through the city. She is very honest and please don't expect any sugar coated feedback (pardon the pun). Thanks so much for your support! read more

My review of Dr. Gabrielle O´Connor is way overdue since she has been my husbandś and mine Dr. for the past thirty years. Itś true that most of the time you have to wait to see her, but thatś because she doesn´t rush her appointments like other Drs do. She´s very knowledgeable and witty.... I love her for that! If you want to be pampered and treated like a flower then maybe Monique her secretary will annoy you, but Monique is hands on and efficient with her work.....just be patient when she ask you to wait on the phone......sheś truly busy most of the time. Dr. O´Connors nurse, Margean, is a lovely lady, and has been working there forever. Sheś very capable, and will never forget to call in your prescriptions. My husband and I love her dearly. All I am saying is that if you´re looking for a competent, intelligent, and amazing Dr.......Dr. O´Connor is the one. read more

Ya it's sad. Dr O Conor is brilliant and most of the time very professional and knowledgeable, but the staff is abusive. I have to see an endocrinologist so often and don't want to drive far, but because I couldnt take it anymore, I left Dr O Connor. To actually leave a doctor that you really need for very serious heath problems because the staff is so disheartening and mean, seems pretty extreme, but that's how hard it was to deal with the staff. read more

If I could I would put 0. Don't even worry about making the appointment because you will not be seen by the doctor during the assigned timeframe. I was waiting for an hour and wasn't able to get it. There were 2 more patients ahead of me who haven't been seen either. Neither a nurse or anyone else can answer a question. "I don't know" Is maximum you can get out of them. read more

Dr. O'connor is an amazing doctor. however the people who work in the reception office are HORRIBLE. i just called to try and speak to them about an omnipod and i was told they were to busy and to call them back. THEY HAVE DONE NOTHING TO HELP WITHOUT COMPLAINING OR BEING RUDE. which is sad because i love Dr. O'Connor read more

Dr. O'Connor was my endocrinologist back when we both were in HMOs, but then due to their regulations, I had to return to my GP for them to manage my endo health. I never felt that same after I had my thyroid eradicated and was on life-long meds. They only treated my labs and didn't bother to hear from me, the patient. After a while I transitioned to a PPO, which empowered me to choose my own specialists. I had developed Epstein Barr, a fatigue syndrome, and was told to amp up vit. B. I returned to Dr. O'Connor and based on her expertise, she tinkered with my meds until I said I felt better, and she monitors any potential side effects. She's been helpful with my transition into menopause, taking lead in treating it while my OBGYN didn't really address any of my symptoms. I highly recommend her, and I've dealt with the same front office personal for all the years I have been a patient, which bodes well for a medical office, in that some have difficulty retaining staff. read more

Dr. O'connor is great. Her staff was able to squeeze me in when I found a lump in my neck postpartum. Her staff is kind, responsive, and made me truly feel like they cared. They were able to electronically send over prescriptions and called me back right away with any questions or appointment adjustments. Dr. O'Connor is a very educated doctor. She knows endocrinology well and was able to answer every single question I had. (I had a lot as my thyroid dysfunction was something new to me.) She took her time during my examinations and explained everything going on step by step during the ultrasounds. I have seen her multiple times over the past year and couldn't be more happy with any other doctor and their staff. read more

I'd like to start with I have only had 2 online video appointments with Dr. O'Conner. Each time she has been to the point, kind and professional. The reason for the 1 star is her office staff Monique is beyond unprofessional. I will more than likely find a new endocrinologist, just because she is so rude when she calls or I call them. I have now had about 5 separate interactions with this staff member and only one time has she been nice. When she called me today to state that the lab could not get proper results from the test I took over 2 weeks ago, she wanted me to find out the fax# for the lab, wanted me to go back to the lab without a lab order and then proceeded to become completely annoyed at the fact that I don't store Westpac labs fax number with me at all times and that I refuse to use Quest as my preferred lab. I have 4 doctors I see on a continual basis and I have to have labs performed every 2 months and have had several issues with Quest over the last 15 years so I refuse to give them my business. I asked her when the lab tech called why didn't she get the fax# from the lab when they called? I explained that I followed the instructions that the lab gave me which were given by the doctor. Why wasn't the lab tech and the doctor discussing how to perform the test instead of me trying to figure it out on my own. Instead she became irritated that I said its not my job to figure out how the test is to be performed and anyone knows you cant just show up at any lab without a lab request. I took the test as directed and why did it take so long for the results, especially when the appointment was yesterday and the doctor never mentioned that the lab results did not come in. I specifically rescheduled the appointment so that they would have the lab results and she knew that. I have a extremely hectic schedule and multiple diseases that I manage, along with two small children I homeschool as well as a full time job and the last thing I need on my list is another rude, unkind human calling me to do her job. I deal with a ton of doctors staff for not only my health but my children's ongoing health issues and if every staff member talked to me the way she does I would seriously think the entire medical community needs to be trained on how to handle on going patients. This is a very trying time for many parents and people with health conditions. All she needed to do was call me back and say I have faxed a new order to the lab and unfortunately you will have to go back for the third time for the test. The doctor has given clear directions on how to perform the test. That's it. Instead because I called her out on her unprofessionalism she hung up on me and now I don't know if anything was completed or not. Now I will be forced to call her again to ask if she did her job. Instead she could be thankful she still has a job and patients that help pay for that job. Doctors work very hard at keeping patients and patient care is a huge part of building a private practice. There is no excuse for her behavior and when a patient requests their lab results it takes little to no effort to print them and place them in the mail, instead of referring them back to the lab. All my other doctors either email or mail me my lab results immediately after the appointment, this office should be no different. There's no excuse for this behavior. Most patients are living in some degree of pain or discomfort and because I suffer from constant chronic pain it just frustrates me that staff cannot find it within themselves to be kind. We all have things going on, we all have busy lives and I'm just over people acting this way. read more

I am so thankful to have found Dr. O'Connor! I feel that she really listens to me and she is extremely knowledgeable; she knows her stuff! Her office staff are very kind and helpful. For many years, I had a thyroid / metabolic issue that plagued me. Dr. O'Connor has been very helpful. Following her recommendations has given me my life back! As mentioned by others, she is a very direct communicator and has a dry sense of humor. I appreciate both. I would recommend her to anyone needing a great endocrinologist. read more

Dr. O'Connor was very helpful and thorough. I previously went to another endocrinologist who completely dismissed all of my lab work and concerns which was extremely frustrating. Dr. O'Connor was to the point and very knowledgeable and took the time to listen to me and explain everything thoroughly. Her nurse and front office are helpful as well. I recommend for anyone looking for a good endocrinologist. read more

I really wanted to come on here and update my review of Dr. O'Connor. She's got a dry sense of humor that isn't for everyone and she is blunt. She's very smart and knows what she's doing and she expects you to listen. She will also help you with many health concerns, not just your thyroid. She reversed a thyroid condition that I was told by a different doctor couldn't be reversed. She was positive on the prognosis. She was thorough with the treatment plan. I would recommend her to anyone needing thyroid help. I stand by what I said earlier, she isn't for everyone but if you want good quality care I would tell you to go to her. read more

Been coming here for years. Office wait is an issue so i plan to wait up to an hour in office. But when I do get in to speak with the doctor it's not rushed, she always answers my questions and we did a lot of bloodwork and other things to identify the root cause of the issue I was facing. Never had a bad day with the Doctor. I have sat in office and had people get angry over waiting, but office staff have always told me prepare for a wait. read more

This is the worst doctor I've ever done business with every time I have an appointment with Dr. O'Connor she makes me wait a minimum of 45 minutes during my last visit I explained to her that waiting an hour and a half is a bit beyond ridiculous -on top of that her staff is incredibly rude. I recently had lab work done so I made an appointment today at 9:45 AM to see to get the results - Dr. O'Connor made me wait once again over 45 mins and her office It's completely empty with zero patients. - Dr. O Connor had nothing but disregard and disrespect for peoples time, she is rude and unprofessional-do yourself a favor and find another endocrinologist - Dr. O'Connor will not respect your time, will overcharge you and her staff specifically Michelle will give you attitude and non stop badgering the moment you do not comply with her demands. read more

Dr. O'Connor is wonderful. I have been looking for a good endocrinologist for years and then I saw Dr. O'Connor on a local advertorial on t.v. I don't usually find doctors via television, however something felt like I should give her a shot. I called and made an appointment and they got me in within a week. She was FANTASTIC! Dr. O'Connor was very easy to talk to and is a straight shooter, none of the typical doctor attitude or stuffiness. She took her time and answered all of the questions none of my other doctors would slow down enough to explain. I would definitely recommend Dr. O'Connor to a friend. An added note: I just read the 1 star review and I think I was a case of Dr. O'Connors fantastically dry humor not being picked up on. She is very caring and very patient. She really is a funny and nice person with a great bedside manor. read more

I have seen Dr. O'Connor multiple times over the past 14 years. She was the first doctor to pin point the cause of a list of ailments I had, diagnosing me with Insulin Resistance. Not only was she knowledgeable but she also sat with me and taught me about nutrition and the proper diet that, along with my medication, could reverse my disorder and prevent it from escalating into Diabetes. She really saved my life, changing it for the better. These negative reviews are mind boggling to me. I understand each situation is unique, but I have nothing but good things to say about her care. read more

If you have hashimoto's I highly recommend this physician. She's kind, thorough and thoughtful. She takes her time and really considers your symptoms. She's incredibly knowledgeable and explains things in a way that's understandable and helpful. I highly recommend her. read more

As someone who has experienced MANY specialists over the last 25 years, I can't speak highly enough of Dr. O'Connor's abilities; it is rare to find someone so knowledgable and enthusiastic. My husband's medical issues have left other doctors stumped and worn out, but from the moment we had our first consultation with Dr. O'Connor 2.5 years ago, I knew she was brilliant and unique. Some patients may not pick up on the nuances of her language and misread what she says as condescension. But honestly, she just has a unique way of interacting with patients. She doesn't dumb down her explanations or say something just because she thinks it's what you want to hear. She's there to tackle extremely complex medical issues and possesses laser-like focus. I personally appreciate her approach. When you've watched a spouse suffer year after year through mediocre specialist after mediocre specialist, you learn how rare it is to find an intellectually-gifted doctor who practices medicine fearlessly and passionately. read more

She is by far the worst, narcissistic, self absorbed Dr that cares more about talking about her own accomplishments & accolades than taking care of her patients. She recommends unconventional ways of weight loss that are not safe. Her office staff is unfriendly and rude. The only decent, kind person in the office is her nurse. I now have an amazing Dr who spends time truly caring about my thyroid & overall health. Steer clear or you will regret this as have other patients that I know. I should have listened to the original reviews I initially read... beware. read more

I found Dr. O'Connor through NAMS several years ago. While I experienced her front office staff as being marginally professional, I tolerated them for the sake of having an endocrinologist close to my home and who was also knowledgeable in her field. Or so I thought until recently when I sought her treatment advice. Without going into the specifics of my medical history, I found her to be defensive and downright rude when I asked questions about my treatment. I have since decided to find another doctor and I would not recommend her to my colleagues or friends. My experience with her and her staff, overall, is unsatisfactory. read more

Dr. Gabrielle O'Connor was Chief of Staff at Mission Hospital Laguna Beach, CA. I have been a patient for over 25 years. Dr. O'Connor saved my life several times and I would not be here today if not for her diagnostic skills and decisive actions. I highly reccomend her. read more

I was referred to this Dr. by a friend who is currently a patient. Unfortunately, the receptionist (Monique) refused to give me an appt unless I told her my detailed medical issues. I did not feel comfortable discussing my medical issues with a receptionist, I just wanted an appt with the doctor. Monique refused to give me an appointment with the Dr! I wonder how many patients this Dr has lost due to this negligent receptionist! Very, very sad. I've worked in the legal field for over 20 years....this receptionist is a lawsuit waiting to happen. Doctor/patient privacy...??? Patient bedside manner? read more

This is for the old hag that works at the front desk. If you've been there, you know her. She is downright mean. She must be related to the doctor bc I don't know why anyone would employ her. She is the rudest person I have ever met. What happened to you to make you such a sour person? She shouldn't have a job interfacing with people. Lock her up somewhere and slide food under the door. This review is for you because at the lowest point of my life when I was gravely ill, you were hateful and mean to me for no reason. Other patients in the waiting room were astounded by how rude you were. The other nurse that works there apologized for you behind closed doors. She's really got it bad--having to work with you must be hell. I was at the pharmacy getting a prescription today and one of O'Connor's patients had to have the pharmacist call the office. I heard your voice screaming at the pharmacist. Made me laugh because years later, you are still mean!! Do yourself a favor--go retire and take some time to ask yourself why you are such a hater. No one, no matter what they've been through, has the right to treat people the way you do. I was surprised you're still there....your attitude costs O'Connor $$$. You are every business owners worst nightmare-you are old, mean, have an attitude, and are an operational inefficiency that costs a business owner $$$. You should be nicer to people and be thankful O'Connor keeps you, because outside your little world behind that desk, you'd be out of work and shit out of luck. read more

Similar to other patients here, I started off thinking Dr. O'Connor was fabulous. One of the few dr's that would prescribe a T3/T4 combo following RAI to get me back on track, I decided the rude front desk staff and obnoxiously long wait times for every apt. were just the price I had to pay. But over the years, especially when I started having issues with my meds, I began to see Dr O'Connor's lack of respect for her patient's time and lack of bedside manner for what it was - rude, condescending behavior from a dr. with a major superiority complex. She wasn't listening to me as a patient rather dictating to me how it should be, while belittling me all the while. I do believe Dr O'Connor has book smarts but her interpersonal skills and blatant disrespect leave much to be desired. I think an environment where she and her staff aren't interacting with patients is long overdue. The way they treat patients just shouldn't be acceptable or ok in anyone's book. If you're looking for a healthcare provider to be a partner in your journey, definitely bypass O'Connor and keep looking. read more

I love Dr. O'Connor! She takes the time to sit and listen and ask pertinent questions regarding your heath! I have referred numerous friends to her and we are all very happy read more

In contrary to a few of the other reviews on this page .... I've had one of the best experiences ever in going to Dr. O'Conner. I had heard she was amazing at what she does and got a little intimidated when I read the reviews speaking to Halberstadt was not the kindest of heart. Every single person I spoke to was so generous and kind and going out of their way to make sure I had an incredible experience. Then I get into the doctors office and she spent so much time with me I really felt like she prepared she was knowledgeable and that she really wanted to help me with my problem . In fact I would be so bold as to say I've never had such a wonderful experience with any medical professional I've ever dealt with in my whole 38 years of existence. read more

I have been practicing family medicine for over a half century and have been fortunate to be able to confidently refer my patients and friends to Dr. Gabrielle O'Connor. As a matter of fact, she's my own physician for several endocrinological conditions that required accurate diagnosis and treatment. I never cease to be amazed at the scope and depth of her medical knowledge and skills! Good medical practice has always been as much of a healing art as a healing science, however few medical doctors still practice with Dr. O'Connor's level of compassion and empathy. Many of my colleagues-- highly esteemed medical doctors-- agree with me that she is "Cut from the Old Cloth"; she is a credit to the medical profession and a blessing to her patients. In short, Dr. O'Connor is among the most wisest and caring physicians I have met. read more

I have been going to Dr. O'Connor for years with a very rare thyroid condition. She is not only very smart, but patient and I like her humor and demeanor. Her front desk staff was nothing but helpful for me just now. I called in and somehow we got disconnected. The nice lady called me right back and left me a voicemail letting me know she hoped that we could connect. Once we talked I realized she had not only already taken care of my question, but went above and beyond to make sure my prescription was ready and enough to hold me over until my next appointment. read more

I went to Dr O'Connor after an ultrasound detected nodules on my thyroid. I knew during my first consultation that I was going to appreciate her style. She has a sense of humor, and a down to earth personality that I've rarely found in a Dr. She spent 30-40 minutes describing what the results meant, and getting a detailed history from me, and I was impressed with the time she took to help me understand what was going on. I needed a fine needle aspiration, and was assured it would be a simple and pretty painless procedure. A friend had one in the bay area, and told me horror stories, so I was a bit skeptical. I'm happy to say that I had it today, and it was a breeze. All my fears were unfounded because it was just a small sting. I'm so grateful to have found such a wonderful Dr. read more

Dr O'Connor is the BEST. My quality of life has been changed drastically for the better since I became her patient many years ago. She is intelligent and has a dry sense of humor which I find appealing. I have hypothyroidism and was taking synthroid prior to becoming her patient. I was tired and gaining weight every year. She prescribed me armour and I have never felt better! I can function and not get wiped out after every little task. She's a miracle worker. I love her and would recommend her to anyone suffering with hypothyroidism. read more

Dr. O'Connor really helped turn my life around. I was headed in a bad direction with my weight and family history with diabetes, and it really had me in a bad place, emotionally. She got my thyroid back in check and helped explain the ways in which I could change my lifestyle and prescribed a plan that I could stick with and its working (and you can't imagine my relief because I've tried everything to get myself back in line with my weight and I could never get it to stick). I've never felt better, my confidence is back, I'm happier, my life is changed for the better. All of my visits to her office have been pleasant, the staff has always treated me very kindly. I highly recommend Dr. O'Connor! read more

I've been going to Dr O'Conner for a few months and absolutely love her. She spends time getting to know you and your concerns. I'm dealing with type 1 diabetes and hashimoto's and she has been terrific. Highly recommend!! read more

First, I want to say I love Dr O'Connor. She's super knowledgeable and smart. I like her sense of humor. But the office staff is so rude I decided to stop seeing her. I was treated horribly when , for the first time since I became a patient, I had to reschedule an appointment. I was scolded like a 5 year old child. When I pointed out my need to reschedule was job related and beyond my control, the woman on the line became even more upset. So I cannot reschedule without being berated , even though I never complained about the average 60' to 90' delay every time I've been to the office? Sorry, my time is also valuable and I don't like being mistreated. I already have a new endocrinologist. read more

Rude receptionist is not helpful and I cannot believe that she is employed. If you want to be mistreated and insulted this is the place for you! read more

I have been seeing Dr. O'Connor for over 15 years. She is incredibly smart and an excellent doctor. I was already a patient when I was diagnosed with Thyroid Cancer. She was awesome through everything and I trust her implicitly. I now see her every 3 months for check-ups and I always leave feeling like my concerns have been addressed and there is a plan of action. I have referred several friends to her and they have nothing but great things to say. She has a dry wit and does not sugar coat anything, which I appreciate. There is no guessing what she means. She gives her honest and succinct medical opinion, and does not beat around the bush. I am glad to have found her and hope to continue as her patient until she retires. read more

All the praise of Dr. O'Connor is absolutely accurate. I thought my life was over after 56 years of Type I diabetes and she saved my life. I am thriving. And, she is indeed a delight. HOWEVER . . . Marianne in her front office is the most rude cantancerous person I hav ever encountered in a medical office. Very unprofressional. If possible, Always insist in dealing with Monique. She seems to try to compensate for Marianne's unbelievably miserable nature. But, Do go see Dr. O'Connor, even if you have to slay a dragon to get to her! It is well wirth the effort. read more

Front office staff is BEYOND rude. I'm shocked the doctor hasn't been sued or had a complaint filed against the office yet. First,it's open enrollment for my company healthcare, I switched health benefits to see this doctor. Our plan went into effect on December 1st, the woman I spoke with told me they refused to see me or make an appt without my new card, which is understandable - but when I told her I would print the temporary from Aetna she told me that wouldn't be good enough. When I looked at my ID card AND called Aetna I was informed what I had printed out is a scanned image of my actual card. I was also informed if a doctors refuses to take the temporary ID as proof I need to report them, I also told the front office they could call and verify my insurance with Aetna directly - which I was told they do not call and verify insurance. Again, I find this very very VERY odd - I've never heard of any doctor not verifying insurance. I also tried to reschedule my appt, because I didn't have my actual card and the woman refused to reschedule my appt until I had my insurance "figured out". I've never been treated so rudely by anyone in my entire life. If this woman dislikes dealing with the public or representing Dr. O'Connor she needs to retire/quit. Oh and the hold times are absurd. STEER CLEAR of this place until they get new front office staff. read more

Wonderful, professional doctor with the most difficult and disheartening front office in OC. Sadly, my wife and I must move on. Just can't take it any more. read more

If I could give this doctor negative stars I would. First let's start with the staff. The staff was extremely rude to me on the phone as well as in the waiting room. I was having some problems locating the office so I gave them a call. They rudely told me they could not help me and referred to me with derogatory names like hun and sweetie. I know I'm young but thats no excuse to not help me. When I finally got there the staff became even more rude as they talked about me behind the counter about my insurance. My insurance bills as blue cross and they did not believe me. They told me to my face I was wrong about my own insurance billing. At this point I was so frustrated I was in tears. Finally when I go to see Dr. Gabrielle O'Connor she tells me she can't help me with my problem and then she goes on to accuse me that I have major depressive disorder. She explains to me that since it runs in my family I must have it. Then she said she couldn't help me with my medical problem so she prescribed me Advil. I kid you not she prescribed me Advil to help me. That should have been a red flag that her entire office is a scam and she is a thief. A few days ago--months after my appointment with her mind you--I receive the bill for my appointment. She charged me $300 for a 15 minute consultation and a prescription for Advil. Fortunately my insurance is covering some of it. She is a thief and a scam artist. How could someone with any moral conscious charge someone $300 for Advil. Mind you, I took the Advil and it did not solve any of my medical issues. Overall, if you are looking to get ripped off by a thief who's staff will treat you rudely go to Dr. Gabrielle O'Connor, she won't disappoint. read more
