A great doctor who always listens, always knows what to do and is always kind.
Fine doctor // horrible medical group. I was seeing this doctor for over a year and when I was changing health plans I made sure I was in his network. They dropped coverage of my plan in the middle of January forcing me to find a new doctor.
Words cannot express my gratitude for Dr. Garen and his practice. Finding a good doctor is tough, I recently moved from NYC to L.A. and had to get an established new network out west. Immediately impressed with Dr. Garen’s demeanor - I’ve been able to be 100% transparent with him, because he instantly made me feel comfortable. He really listens, spends time, and makes himself more human vs doc - and easy to relate to. Additionally, he made fantastic referrals for specialist I was looking for. All in all, I feel so fortunate to have found my new primary! Hard to find the good ones these days!
Everyone in this office is really chill and nice and prompt. Dr. Derhartunian is really thorough and does a good job at making you feel comfortable. He communicates well and doesn't use confusing, convoluted language. He also seems really informed on medical studies and is eager to share that knowledge with you.
After three years, I finally found a PCP in LA! Dr. Garen and his staff were excellent. I'm used to feeling very rushed and like just another number at doctors, and didn't experience any of that with Dr. Garen. I was able to have a real conversation with him and talk through concerns, without any feeling of rush , judgement or quick assumptions. He took the time to understand more of what may be the underlying issues and the multiple options I could take moving forward. He even let me do a couple more examinations during this single appointment. I highly recommend Dr. Garen!
Dr. Derhartunian is the best doctor. I have seen many doctors over the years and I highly recommend him if you want a caring doctor who will take his time with you, make you feel comfortable and treat you like a patient should be treated.
Very nice people and super fast !
Dr.Derhartunian and his staff are top notch professionals. I have been seeing Dr.Derhartunian and Dr.Tovmassian for a little over a year and I have never had any problems in scheduling or anything for that matter. Great doctors and great staff!!!
Absolutely terrible, complete fraud. These people will never stop billing you. Since January 2017 I have received more than 7 "past due" bills to my home for an annual checkup I had in August 2016. This bill has been PAID IN FULL. I have been on the phone with Blue Cross (my insurance provider) on more than 7 occasions to confirm that full payment was received and to rectify the situation with Dr. Derhartunian's office. Blue Cross has flat out told me that Dr. Derhartunian's office is blatantly disregarding the fact that the bills have all been paid and that they are practicing shady activities. Blue Cross has personally sent me paper confirmations that the bill has been paid in full and they have spoken to Dr. Derhartunian's office each time I've had to call them, and each time Blue Cross calls Dr. Derhartunian's office, his office swears that they will finally remove me from their billing system. Not so: I just got off the phone with them (August 18, 2017) and they are once again (I believe this is threat #8) threatening me with a "past due" bill! I informed them that this is completely inaccurate and that they received payment a year ago, and this was breaking news to them. SAVE YOURSELF THE HEADACHE AND DO NOT VISIT THIS DOCTOR OR ANY OF HIS ASSOCIATES. I'm at a loss as to what to do and I may have to take legal action if they do not finally listen. I wasn't going to write a bad review but this was the last straw for me and I want to warn all others out there that you could find yourself in this very same situation if you visit Dr. Derhartunian's office.
I'm glad I found Garen. He's a very genuine doctor.
Dr. D has been my general practitioner for more than a year now, and I am so happy with my choice. He's professional, cordial, and I always feel like he has my best interest at heart. Also, his staff are amazing! Can't recommend him enough!
I was worried after we moved to a new area about finding the right PCP. We found ours on the first try. He gave us a lot of information in the first visit and addressed all of our health concerns.
Is it Great and an understanding doctor
Really nice experiance. I think I've found my new doctor.
Dr. Dehartunian is thoughtful, skillful and kind. He is a great internist with the feel of an old time family doctor. The care is comprehensive and compassionate.
The office is always welcoming and accommodating upon arrival whether it be for a checkup, follow up, or a sick visit. Staff is friendly and considerate, and Dr. Derhartunian is thorough, thoughtful and always makes sure you come away from the appointment more knowledgeable about your own health. I am always more optimistic after an appointment here!
Best and most caring doctor you will find anywhere. I have a lot of medical issues and he treats you as a whole person to get the best results. I trust him and that is vital in a doctor patient relationship.
Everything was great. I wasn't crazy about all the duplicate information on the forms
I was really nervous going in but the whole vibe of the office is calm and friendly. I was seen immediately and every single one of my questions were answered. Everything was explained to me, and I absolutely would recommend this doctor and practice to anyone. I'm so happy to have found a doctor who really seems to care and understand.
Doctor took time to not only listen to my concerns but also made sure to follow up on them by checking my condition. I did not feel like I was being rushed as I have previously with many other medical practitioners. Would highly recommend!
Very kind doctor and he helped with my needs. Very intelligent!
It was excellent ! Great Doctor, great facilities !
First off, both the receptionist and the Doctor were very friendly and professional. They diagnosed me and told me what the ER wouldn't a few days before. Gave me instructions on how to treat it and gave me the good news. To top it off, they gave me a doctors note for the days I missed at work. Amazing service, amazing human beings. I sure know how to pick them.
Listened very closely to my concerns and discussed available options. He also understands that I pay out of pocket so he tries to give me the cheapest alternative.
Dr. Garen listened to me and helped me in the best way he thought possible. I'm very glad that he cares about his patients.
I'm very happy to have found Dr. Derhartunian. I feel as though he's committed to providing as much value as possible with each visit. He'll even take the time to look things up on Google with me to illustrate our discussions. Very thorough, kind and friendly doctor.
Very pleased to find a thorough, knowledgeably doctor. Answered all my questions and took his time. Easy parking as well!
He was very thorough in trying to understand my problems and gave me a list of solutions to choose from. Very nice and professional.
Great doctor. Straight to the point. Highly Recommended.
Maybe the best bedside manner I've ever encountered, doesn't dumb things down, answers all questions with the patience of a saint.
Appointment was easy to make. The office called right after I submitted my request on Zocdoc. Everything else was smooth and easy. Don't bother filling in your patient info until you arrive.
Dr. Derhartunian and his team were very nice and helpful. I highly recommend him!
Awesome doctor! Very thorough and nice.
At first I was skeptical as to how a doctor could garner so many five star reviews. The ease and convenience of making an appointment was a good start, but the location of the office also was great! Lots of parking and not difficult to find. The staff was very helpful and friendly and just overall efficient. I guess I should have prefaced this with the reason for my visit-- I was in the market for a primary care physician after receiving a new insurance plan. I don't remember the last time I had a physical, so I was nervous about having blood drawn. Actually, I kind of legit freaked out. I started sweating profusely and my heart was racing and I was scared I was going to pass out. After being honest with him and telling him I would rather skip the needle today, and he was totally (well, almost) able to calm me down. He even offered to draw my blood himself! The girl at the front desk came in to hold my hand and talk to me, and it was over in no time. It's obvious why Dr. Derhartunian has such rave reviews-- he goes above and beyond and it does not go unnoticed. He has a terrific bedside manner, and is very charming, professional, and knowledgeable. It was actually a pleasant experience and I'd recommend him to anyone without hesitation.
I was in and out - yet, I felt thoroughly examined and cared for. This office has it down!
Great, easy to talk to, understanding and kind staff
Professional, forthcoming, unhurried, willing to share nuanced information. Treated me as a peer, without condescension, while being knowledgeable and reassuring. I left there feeling I understood the big picture.
Not only treated me for what I came in for, but filled all my other prescriptions - no hassle! Will be returning - kind and efficient!
I have many medical issues and have seen many docs (good and bad) over the years . Dr Derharunian is a great doctor. He actually listens, cares and provides the best medical advice that I have ever had. I would recommend him to anyone who needs a truly caring a great doctor.
Great visit! Everyone was so nice and Dr. Derhartunian was thorough with a great bedside manner.
First timer, And I went to the wrong medical building across the street, but the receptionist on duty was very sweet about it all! Dr Derhartunian and RN Lilia were both fantastic, very personal and easy to talk to. Lilia is particularly blessed with the needle: no bruises! Dr Derharturian was to the point but took the time to make me feel comfortable at the same time. I've very happy I found this office!
I think he is an excellent doctor. Part of being a Doctor is just listening to the patient sometimes. I know my body, and what I'm feeling. I appreciate that he just let's you speak before he diagnosis you. Peace of MIND and body!
He's very punctual, doesn't make you feel rushed, and is very attentive. His staff is also very professional.
Such a great first visit- he listened to everything I said and offered really good solutions. I have a new doctor:)
He's incredibly kind, understanding, knowledgeable and efficient. Extremely pleasant experience overall.
Dr. Derhartunian was great and I'm very happy with my visit! I was looking for a new primary doctor and I think I'll be staying with him for now. I had no problems getting checked in or anything and the doctor was funny and kept things light-hearted as we talked about my previous medical history - he definitely made me feel comfortable. Also, he was informative in terms of how I can arrange my appointments and how often I need to be coming in for certain check-ups. Overall, I'd recommend him to anyone that's looking for a new doctor!
Dr Garen was great - friendly and helpdul
Great doctor! Amazing experience.
I was quite impressed with Dr. Derhartunian and his staff. He is really a good guy and the ladies were very accommodating.
Super friendly staff, and Dr. Derhartunian is very down to earth and efficient. He really took his time to understand my concerns and went above and beyond what I had originally scheduled my appointment for. Will definitely be keeping him as my primary care physician!
First time with Doctor Derhartunian and it was an excellent experience. He was knowledgable and down to earth. I'll definitely be using him as a primary care physician.
Fantastic experience. Very personable, down to earth, easy to understand and communicate with, and left me feeling so much better than when I had walked in. Will return again for sure.
Dr Derhartunian was personable/knowledgable and I would highly recommend him as a family doctor.
This was my first appointment with Dr. Derhartunian, for an annual physical- the doctor lived up to his high ZocDoc rating. He has an authentic bedside manner, and took the time to address my questions. For my allergies, Dr. D proactively explained the mechanism by which various antihistamines work in the body- the first time I've ever had a doctor use a nice teaching moment. I will be returning to this very nice little office, with friendly staff. Next week: blood draws- review to follow!
Dr. Derhartunian was excellent!
Dr. Garen Derhartunian is an awesome doctor. He gives a thorough and un-rushed check up, then back's up his advice by looking up evidence on his computer, talks through photos, and gives suggestions for health. He's a total pro and I highly recommend him!
This was the best doctor's visit I've ever had. Though this was the first time I met with Dr. Derhartunian, his bedside manner and overall demeanor immediately put me at ease. Like a lot of people, I'm not particularly fond of going to the doctor, but a visit with Dr. Derhartunian diffused a lot of my concerns and nerves. He really took his time, and ensured that all of my questions were answered. Though I went in for an annual physical, he wanted to make sure that any concerns I had were addressed that day. We'll see how follow-up visits go, but I'm confident that Dr. Derhartunian will continue to be my primary care physician for the time being. (additional note: I had some blood work done, and Dr. Derhartunian called me himself to discuss the results. I felt very cared for and attended to.)
Dr. Dehartunian is a wonderful doctor. His staff is also very personable and the office is very well run.
He is the best ever. You will not find better, more personalized care anywhere.
Very quick and easy! Clinic was nice and clean!
Dr. Derhartunian is amazing! Professionalism and knowledge makes this doctor standem out!!! Thanks again Doc, -Robert-
I've not met many Drs that I felt totally comfortable with talk about my ailments and body so this was a first for me. He was knowledgable, personable and gave practical recommendations. His staff was fast, friendly and efficient. The appointment was on time too.
Best doctor hands down!
My visit went really well. He listened to what I had to say, checked me out and diagnosed my ailment and gave me what I needed to get over my ailment. Very good doctor.
Dr. Derhartunian is very professional. His office is very clean and welcoming. I booked him since I needed a next day appointment, but will be going back to him for any further medical needs.
Dr. Derhartunian really took his time to address my symptoms and was happy to do a deep dive and run all tests necessary to rule out other possible causes of my illness. All the while he had a great sense of humor, was kind and very reassuring. Happy to say I am on the mend and now have a great PCP in Los Angeles!
Dr. Derhartunian is great! Very personable, friendly staff and a clean and comfortable office. Highly recommend!
Great doc. Think I found my new PC physician.
Very considerate, nice, and open to any questions you might have.
Very thorough physician who really takes his time to listen and address all your concerns. I found him on zocdoc because none of the PCP's in my area had same day availability, but now I can confidently say I won't be staying in my area in the future. Will be going back to see him !
One of the best experiences I've had with a doctor. He took his time with me and was thorough with his explanations and it didn't feel like he was just treating my direct symptoms because he took a more holistic approach to the questions he asked about my lifestyle. Highly, highly recommend him!
Dr. Dehartunian is a great doctor. He addressed all of my health concerns accurately and efficiently. His office is bright and clean and the office staff friendly and helpful. I would recommend him without reservation.
Offices were very new and clean, I only had to wait a few minutes to see the doctor. Dr. Derhartunian took the time to ask me questions and was very friendly. The staff were great too, very friendly as well, they were a nice way to start the appointment.
He was very thorough. He doesn't leave until every question has been asked and he fully explains everything. The nurses are great and the office is very clean.
Great appointment. Spent a good amount of time talking to me about my issues and discussing options for moving forward.
Best doctor experience I've had in years! Highly recommended!
I was a practicing doctor for 38 years and it doesn't get better than this!
Best doctor visit experience I've had.
Dr. Derhartunian was great. Visit was quick, the doctor explained the reason for doing everything he did, and is conscientious about long-term health and quality of life, not just of yourself, but of others as well.
Very easy to speak to. He listens well and explains everything he's doing and why he's doing it. I've made him my primary care physician because of his politeness and professionalism. With other doctors I was just another patient they had to deal with, but not with this doctor.
