This review us for the RECEPTIONIST ONLY! I would have given her a 0 if there was one available. She's Condescending, making patients feel inferior, no empathy, or willingness to understand and support patients! The DOCTOR however GREAT, and it's a shame that his practice reviews are affected by a terrible employee work ethics or the lack of. read more

Doc is good, Debbie the office manager is not very friendly and never follows through. I have left this office 1.5 + years ago and have tried to get all my records for my new endo. To this day they still don't have them. I also needed them to send records previously for life insurance. After 20 plus request from insurance company, they had to send someone there to copy them. Trying to get scripts should be simple but it was the hardest thing. read more

I have seen Dr Mach for 25 years he's wonderful. The current situation with bloodwork and setting things up through quest is a JOKE ! Multiple attempts to get that done resulted in no one that knows anything about it and calls to confirm go unanswered. This was not a problem until this last year and the personnel in his office could not be more unhelpful ! They would be more helpful to not EVER answer the phone. I have canceled my appointent and requested a call from the doctor himself however I have absolutely no doubt that he will not get that message. Setting up an appointment with a new doctor, this review is my only vent. So if you need a great doctor Dr Mach is your guy if you want to set up bloodwork and an appointment and see the doctor then call anyone else. read more

Debbie front desk talks down to patients. Is not a nice person Over and over again no matter what the request she barely looks up and never a pleasant smile read more

I have been a patient here for many may years and I have reached my breaking point, Debbie in the front office should not be in that position. She is an insufferable human. She is not helpful, warm or friendly. The office cut the contract with my medical insurance since my prior visit, When I arrived for my appointment I was informed that she will not process my claim as out of network because that's not her job. If I wanted to see the doctor I would have to pay as a cash payment office visit. When I asked for a receipt so I could submit the claim myself, she refused to provide one with the diagnostic code. Needless to say, insurance denied it because it did not have the proper information. My many attempts to obtain this information have gone unanswered. When I spoke to the doctor about the concerns I was told he is one of the only independent endocrinologists in the valley and Debby can run the front office however she pleases. That was the final straw for me Ironically after months and months of trying to obtain a receipt to no avail, when I asked for my records to be transferred over to the new practice I chose, the request was acknowledged and completed within TWO HOURS! Good Riddance. read more

The office lady is horrible. She is like talking to a bent trash can .she doesn't listen and treated me like a idiot

Had an appointment today was disrespected by the front desk denied to see me when they had a clear form that I have an approved referral the lady did not check her system that they take HMO discriminated me by saying that Medical patients are for people with no job??? Like she doesn't have work ethics Medical is for anyone with a job or not with low income get educated pls. Second of all I have HMO but clearly you were too lazy to check. Don't bother coming here rude and discriminating. Lady I have a job I pay my taxes just like you please make sure you are well educated. Stop treating patients like crap your making the Doctors office look bad with your poor work ethics. Spoke with my insurance and they told me I was supposed to be seen and I decided to file a report. For the lady who attended me Maybe you need a different career path if you can't simply treat patients with respect Her name starts with a D and she claims to be the manager. read more

I recently switched physicians and Dr. Mach is a lovely doctor. Unfortunately after he wrote me my prescription, my insurance company asked him to call in a pre-authorization. His office staff told me their office policy is that he won't contact the insurance company and the pharmacy needs to call them. The pharmacy told me my doctor needs to contact my insurer. I am stuck in the middle. As a result of this, I can't get my medication filled and have to go find another doctor just to have my prescription covered by insurance. I am very upset. read more

I have been seeing Dr Mach for over a year now. His staff is courteous and friendly. The facility is clean. And Dr Mach himself is friendly and professional. He has always gone over all my lab work with me and explained what all the numbers mean. He has given me multiple treatment options and discussed in detail with me so that I may choose the best option I feel comfortable with. His facility was able to do my bloodwork and ultrasound all on the same day, which is awesome. Parking was simple. Overall a great experience. I am truly happy with him and his staff! read more

See all

Dr. Mach is a wonderful and very knowledgeable endocrinologist. He is honest and kind in his assessment of patient situation, but gives it to you straight. I am so happy we found him for my type 1 son. The office is very friendly and caring, but it can take some time for them to get back to you. There is a serious shortage of specialists out there! read more

Office staff Debbie and Pio were very efficient Dr Mach was great didn't rush through my appointment listened closely to my questions and his answers made so much sense to me they was they were explained read more

Poor doctor communication if any at all. Left many messages including negative side effects from meds and no calls back. Office staff is underqualified to handle even the most basic tasks like emailing lab results. I requested them 6 separate times and still the staff has not emailed them. I have a right to my medical records and for them not to send them to me is a violation of HIPAA. Plus the doctor proceeded to mansplain to me immune deficiency disease on my first appointment. I am a medical student. I found his demeanor condescending and misogynistic. Office is dated and not clean. I felt rushed out of my appointment and the doctor didn't seem on board with my choice for non synthetic medication options when discussed. read more

If you are looking for a decent standard of care please DO NOT go to this doctor. His knowledge, availability, patient-physician manners, staff, facility and overall office organization are so lacking that you would be better off anywhere else. I really recommend any potential patient trying another physician in the area. I cannot emphasize enough how poorly he and his staff treat his patients. read more

I just want to ad to my review that Dr. Mach is knowledgeable in Thyroid disease and Type 2 Diabetes. I just felt that he wasn't so helpful with Type 1 Diabetes and figuring out how to deal with my issues. I also agree with DD in that getting the office staff to sent scripts and Prior authorizations done in a timely manner doesn't happen. It too was frustrating for me whenever I called and asked for something to be done. read more

I would be cautious of seeing Dr. Mach. There is so much inconsistency with his scheduling because he is on vacation or decides to move his schedule to limited hours. I had multiple appointments moved and now because of his scheduling issues I don't have access to my medication. This man is dangerous to anyone that is looking for a doctor who genuinely cares for his patients and their concerns. read more

Dr. Mach is a more-or-less adequate Endocrinologist. He is out-of-date on the latest in Diabetes management software, and recommends fixed-dosage insulin, instead of a sliding-scale based on apps or charts that will do dosage calculations based on Blood Glucose levels. His office is staffed by incredibly incompetent and ineffectual individuals who constantly talk over you, do not understand the basics of time management, and are overly-empowered by Dr. Mach to be rude, condescending, and often pass biased feedback to Dr. Mach to influence his interactions with patients. I sent Dr. Mach an invite to share data from my Jade Diabetes management app this afternoon, and was called by someone from his office to say he was waiting on my data... Rather than just work through why he could not find the software in his email, he had this 3rd individual in the middle, relaying information to the Doctor who was on his computer. It was wholely unproductive. I missed by 2pm time slot, and was told he would call me back... It is now 5:07pm, and I have called his office twice and was unable to get through. This is no way to run a practice. In the past I have waited for two weeks to get a scheduling callback from Dr. Mach's staff. I would avoid Dr. Mach's practice like the plague. read more

Dr. Mach is very knowledgeable, answers all questions and works with his patients in shared decision making. Great physician.

Dr Mach was very thorough in taking my history, reviewing my medication list, and trying new medications to get my diabetes under control. Very professional, very nice man. read more

Outstanding endocrinologist and gerontologist. Articulate, knowledgeable, friendly. Takes time to sit down and really explain things. I'm a physician and I chose him for my father and myself because of his great qualities as a physician. He's a true physician's physician as they say. (Hint: Those are the kind you should look for) read more

Dr. Mach was great at explaining my diagnosis and test results. He even drew me a visual to make it even more understandable. Debbie at the front desk was a great help in getting an appointment and submitting my tests so quickly. I appreciate her flexibility and care! read more

Thanks Doctors Mach Minh for your help to my husband Son La with your caregiver ours family really appreciate

Dr. Mach is a very good doctor. He takes the time to talk with you and go over labs and options. I see him for thyroid issues and am very happy. The office staff is very friendly. The new location in Burbank not the most desirable location, but office was clean. read more

Dr Mach is very thorough and spends a lot of time with you explaining all your results. He actually remembers you from your last visit. He is very caring and amazing bedside manners! read more

I just left an appointment with Dr. Mach for my girlfriend and he is very thorough. She had concerns that she might have hashimotos or thyroid issues and he first went over all the symptoms she's experiencing and then went as far as drawing a graph on a piece of paper to describe how the thyroid can affect your health. He then ordered a blood test and told her that he will call us for next steps after he reviews her blood results. There are many reviews about the front desk (they were very polite) and/or how long they take to call you back - I can't comment on the latter as we are now waiting to be called back. I put 5 stars for our experience with the doctor, his knowledge, his communication, and making sure that we had no questions when he finished the exam. read more

WORDT ENDOCRINOLOGIST I HAVE EVER SEEN IN MY LIFE. is obviously paid to push certain types of new medications. I've been diabetic since i was 11 years old, I'm 25 now and have never encountered such a childish doctor. He threw a fit when i denied bloodwork because i had no one to drive me home and slammed his office door like a 5 year old child not getting his way. Along with this he prescribed me the wrong type of insulin twice. Stay away from this office. read more

Uhhhhhh so I have been paying out of pocket to see the BEST endo in LA (Dr Jordan Geller) and tried to go cheap by getting a referral to an insurance covered guy... which led me to Dr. Mach. Upon seeing me for the first time, he asked me a couple questions about what I was taking, explained things to me that I already knew, and took out his note pad and wrote me a prescription for medication. Keep in mine, he hadn't seen ANY blood work. He then told me to go get blood drawn to check my thyroid and cholesterol. I asked if it would be better for me to do it after fasting and his reply was, "Yeah, it will be more accurate then, but its fine if you do it now." Uhhh??? So I came back the next day to get a FASTING blood test, then waited and waited and waited. No one ever called me with the results. Back to Dr Geller it is! You get what you pay for. read more

What a jerk! I went to see Dr Mach to explain some unexplainable weight gain and the first thing he does is try to feel my thyroid. He starts giggling and says, "Ha ha, your neck is so big I can't get my hands around it!" Instead of making a small hands/small privates joke at his expense, I waited it out and hoped he was actually good at his job. NOPE. He did bloodwork and I went to a follow up appointment where he was an HOUR late into the office. There he explained nothing. AVOID THIS DOCTOR. read more

I have been Dr. Mach's patient for many years. He listens intently to my concerns and gives sound medical direction, in addition to lifestyle advice to improve my diagnosed condition. He practices what he preaches and is an excellent example of the abundant life his patients can enjoy if they would follow his advice. It is a joy to be associated with him. read more

I'm shocked at read g some of the reviews of Dr. Mach. He's been my doctor for over ten years. He is nothing like the bad reviews I've read! He's always been very professional, and a very good listener. I have had dcellent care as his patient. I've revommended him to several friends, and they are all satisfied read more

Dr. Mach is great. He takes his time and answers all of my questions. I hardly ever wait and I also love the fact that there is a lab in the office. His staff is amazing as well. read more

I have been seeing Dr Mach now for years after being diagnosed with Hashimotos Disease. He always takes his time with me, answering any questions I may have and reviewing my blood work. I never wait long. The man in his office who draws blood is really good, never ever wait and he gets there early so you don't have to fast too long in the morning! read more

This doctor needs to learn how to listen and talk to patients. He is awful. He is dismissive and does not listen. He kept telling me there was nothing there and I could not feel a lump. My GP felt it and I did! Tried to talk me out of a scan but my GP had it done and it was cancer. Thanks for nothing. read more

Dr. Mach is easy to talk to, very knowledgeable, and clearly explained and anwered any questions I had. And when I had follow-up questions later on in the week, he called me back in a timely fashion. Like most doctors, he's busy and rushed, but he did take the time to call and answer all my questions. Having a phlebotomist in the office is very convenient, and he's very good. Wait time is fine. Office staff is nice. Phlebotomist is a pro. I'm just very happy I was referred to a great endocrinologist. read more

Avoid this doctor at all costs. Dr. Mach and his associates are very skilled, but they employ the most unprofessional office staff ever. Find another provider. There are plenty of skilled providers out there that hire qualified, professional front office staff. read more
