She has been my primary doctor for about 30 years
8/20/2026
Dr. Naemi is always caring and listens. She is thorough and has always made sure that my health issues are carefully monitored and will not hesitate to follow up with an email, or even a phone call. I know physicians and medical professionals are overworked and stressed, but she and her staff strike the perfect balance of managing time with me and other patients. I never feel like anyone is in a hurry. I truly feel heard and cared for. That is why she is still my doctor after many years, and despite the staff under her changing throughout the many years, the staff still remains caring and professional. It truly is amazing. I am so thankful for each staff person that surrounds Dr. Naemi and am so thankful that Dr. Naemi is still caring for me as my doctor.

Dr. Naemi is a very caring and personable doctor and I have been seeing her for years. Have introduced my whole family to her and they are all seeing her now. She has time to talk to you if you have a problem and is never rushing to the next patient.
