TODD KAYE, MD REVIEWS

He is the most incredible doctor I have ever had. He listens, encourages, cares, and pursues solutions. He has never not gone above and beyond, and is always approachable. I can’t say enough great things about him. He has saved my life, and I am so grateful to be in his care. He is the absolute best person and doctor I have had the pleasure to work with.

Dr Kaye is by far the best endocrinologist I have worked with. He has a warm manner and a quick smile. He will give the relevant information in terms as simple or as technical as the patient requests. He worked with me instead of ordering me. Based on the data I gave him between visits he adjusted my medications so I could make faster progress. My numbers are at target and I have sustained them thanks to his problem solving and encouragement.

Dr. Kaye goes above and beyond with regard to his care for his patients. He is responsive and caring and will always answer your questions/concerns in a timely manner. Highly recommend.

ANNE PORZIG, MD REVIEWS

She has an excellent bedside manner and all the fine needle biopsies that she did on me or not painful at all which is very surprising. She's kind and thorough.

Dr. Porzig and her team are absolutely amazing! My mom had an abnormal ultrasound result for her thyroid and was scheduled to see Dr. Porzig today. Her medical assistant team was incredibly caring, personable, and just all-around wonderful. Dr. Porzig herself is an exceptional doctor who is extremely knowledgeable, enthusiastic, and so compassionate. My mom said she made her feel so comfortable and had such a great presence that it immediately put her at ease. Dr. Porzig performed a biopsy with her medical assistant, and my mom said it was actually a pleasant and easy experience. We both left feeling very positive about the outcome, and my mom was in great spirits. Dr. Porzig is one-of-a-kind, and we are very grateful to have her expertise and support during what would normally be a stressful and scary time.

Dr. Porzig is knowledgeable, kind and helpful. She is the best! She is clearly on top of the most up-to-date medical research. She is also very friendly and kind. She made me feel a LOT better about my diagnosis. She is great at staying in touch with her patients. She replies quickly to emails. PAMF is truly a magical place.

JULIA J. CHANG, MD REVIEWS

Dr. Chang was thorough in her review of my bloodwork results and provided me numerous opportunities to share or ask questions. She proposed different means that might increase my energy level and we discussed them before allowing me to make the final decision on whether or not to act on her recommendations. Dr. Chang provides excellent care and always demonstrates concern for my health. I trust her judgement and professional insights.

My top doctor. She explains both sides to any changes and very easy to talk with. Hope she remains my doctor for years to come.

Incredibly friendly and very interested in the lives of her patients to make them better. She is very accesable, pleasant and helpful. I am glad we connected.
