DOROTHEA E. SPAMBALG, MD REVIEWS

My life changed when I met Dr. Spambalg. She taught me how to take my thyroid medication to make it more effective. She treated a growth in my thyroid and has helped me with changing my physical health. She is one of the smartest people I know and I highly recommend her. She is a "tough love" physician, and that can be difficult, but it's worth it for me and my health.

Is no nonsense (but is nice and considerate about it), follows up like no ones business, has an amazing front desk staff who are ON TOP OF IT. Does it hurt my pocketbook that she is Out of Network Yes a bit, but I also do the work on my end to get that handled with my insurance afterwards. It is worth it, because i feel very much that I am in good hands. Now that I have a kid on the way, oh man, you best believe I am only going to work with a medical team I feel to be in good hands with.

My husband and I both see Dr. Spambalg. I have thyroid issues and he has type 1 diabetes. She is absolutely the best doctor we’ve ever had. She’s caring (sometimes in a tough love way, which is a good thing). My husband’s management of his diabetes is the best it’s ever been thanks to Dr. Spambalg. She’s punctual, but you never feel rushed. She makes us feel like she really cares and is invested in our health. Even though she doesn’t take insurance, she’s worth it. She doesn’t take advantage of that, and it allows her to make decisions based on what’s best for her patients rather than what the insurance company thinks is best. We highly recommend!! And her staff is great too.

MAHTAB SOHREVARDI, MD REVIEWS

I would like to express my deepest appreciation for Dr. Mahtab Sohrevardi and the exceptional care and support she has always given me. She is not only an outstanding endocrinologist, but also one of the most compassionate, caring, and dedicated doctors I have ever met. Dr. Sohrevardi treats her patients with genuine kindness and supports them as if they were members of her own family. She always takes the time to listen carefully, understand every concern, and explain everything with patience and clarity. I have never felt rushed during my appointments. She makes sure that I feel comfortable, informed, and confident about my health and treatment. Her knowledge and professionalism are truly impressive, but what makes her especially wonderful is the personal care and emotional support she provides. She genuinely cares about her patients’ well-being and always goes above and beyond to help them. Knowing that I have a doctor who truly listens, understands, and supports me has made such a meaningful difference in my life. I feel incredibly fortunate and grateful to be under her care. Thank you, Dr. Mahtab Sohrevardi, for always treating me with so much compassion, respect, and kindness. I highly recommend her to anyone looking for a knowledgeable, trustworthy, and genuinely caring endocrinologist.

as a physician, i can't say enough about dr. sohravardi. I share multiple patients w/ her and I'm consistently impressed with her diligence, attention to detail and commitment to continuity of care--maintaining communication to ensure we're all on the same page.

She is a compassionate caring and highly knowledgeable doctor. I am lucky she is my endocrinologist.

JHANNA ALEXANDRA NARIYANTS, DO REVIEWS

I was referred to Dr. JHanna Nariyants by my primary doctor because of issues with my thyroid. I was impressed right away by her! She explained to me everything that I needed to have done, and she was so thorough and pleasant and made me feel so at ease.

Dr. Nariyants was very thorough in her explanations and seemed genuinely interested in my situation. She has an excellent bedside manner. I felt very at ease with her. I would recommend her to anyone needing an endocrinologist.

I would also like to thank Brenda, her medical assistant. She was so thorough and pleasant. Way to go Dr. Nariyants and Brenda.
