THOMAS G. AHN, MD REVIEWS

Dr Ahn is the best doctor I have ever been to. I live in Santa Clarita and I happily drive to Century City to see Dr Ahn. I’ve been seeing doctor Ahn for 8 years. He’s professional in every way and more importantly, he’s incredibly thorough. Dr Ahn is never rushed. He will sit with you and review your medical history, asking all pertinent questions. He runs his office the way doctors used to run their practices before insurance companies turned it into a factory.

Dr. THOMAS Ahn has been my Doctor since I was 24 and I’m now 53. I struck GOLD when a friend referred him to me. Dr. Ahn has saved my life more than once and my husbands as well. He’s so professional, hard working, so smart, and gets back to you immediately .i’m so grateful to have him as my doctor and recommend him to everyone I know. He takes you in his office first and goes over your history in great detail and listens to everything you have to say. I really can’t say enough about him and his staff. Thank you Dr. Ahn and all your staff for taking such great care of me all my life.

Dr. Ahn is an absolute incredible doctor. I’ve known him for many years. He’s diligent and a real professional. I highly recommend him.

SUSAN PEKAROVICS, M.D REVIEWS

Dr Pekarovics is exacting and precise. She will find the problem & treat it with the least invasive method. Her staff is professional , smart and kind and is always willing to help. Plus the office runs on time. Wearing 4 hats with internist , endocrinologist , fibromyalgia and anti-aging Dr Pekarovics is one of a kind.

DR. SUSAN PEKAROVICS thank you so much for your professional.I appreciate her call backs regarding lab results and radiology results.She is an amazing physician.I went to DR.PEKAROVICS with several chronic issues and she tray to provide the best services.Dr. is the very best and her staff is amazing!

I felt very comfortable and in perfect hands with doctor Susan Pekarovics. The most professional and best medical experience I have had, lovely and compassionate doctor. The energy in that office is so warm and welcoming, her stuff was accommodating and I never had to wait more than 5 minutes, the stuff is wonderful. Dr. Pekarovics is simple one of the best doctors you can find!

THEODORE C. FRIEDMAN, MD, PH.D REVIEWS

Dr Friedman is the most knowledgeable & compassionate Dr. I had a long journey with Cushings diseases trying to get diagnosed and getting dismissed by so many other drs, but Dr Friedman listened to me and knew exactly what to do. He has gotten me so far and I am now 12 days post op from pituitary acth Cushings disease, I traveled to MD Anderson to his neurosurgeon he recommended & got both pituitary tumors removed. He kept fighting and testing because he knew, if you need a Dr to listen and a Dr that knows what they are doing I would 100% recommended Dr Friedman. He saved my life, as a 24 year old I can’t even express how grateful I am to him. If you need an endocrinologist especially for Cushings disease I would not even think twice about booking an appointment with him!

I just had my 3 month follow up phone appt with Dr Friedman. Thank you, Thank you, Thank you Dr Friedman for always listening to my symptoms and not just treating me according to the lab values. Helping to fine tune my every hormone level and then some! We have been doing this for over a decade now and there is always hope with you! We are so blessed that you have made our chronic endocrine illnesses your life's work. If you are an endocrine patient complicated or not and you know in your heart that you can feel better or you just dream to get your life back from chronic hormone issues, then RUN don't walk - find a way to make an appt with Dr Friedman. When other drs have said this is the best they can do for you. Please don't give up on yourself. You can start by looking at the website, watching you tube or joining the Facebook group. I'm just one patient but if you really want to feel better than I encourage you to get on your computer and see that I am not the "only one " who has had their quality of life changed by his care, empathy, compassion and all without judgement. All the reviews are why we affectionately call him " The Wiz"! Dr Friedman treats your whole body,mind, so

I tried local endos who did not take the time to address my daughter’s abnormal test results. We saw Dr Friedman via telehealth and he is pushing forward for her. He has already helped so much.
