Insurance

Yes — we take your insurance.

Patient stories

Real names. Real outcomes.

Real reviews from Dr. Hashemi's patients.

Second to none
“Dr. Hashemi is an exceptional physician who genuinely cares about her patients. Her knowledge and expertise are second to none, and she takes the time to explain everything in a way that’s easy to understand. She listens attentively and makes you feel like you’re her only patient. Highly recommend Dr. Hashemi to anyone seeking top-notch care!”
Sam SimaniPatient
Caring to the end
“Dr. Hashemi took great care with my 99-year-old mother for the last several years of her life. She was there for her, checking in every time my mother was in the hospital, right till my mother’s last breath — and I just love her. She made sure my mother understood her, and that we did too. I also loved her staff, who were always kind.”

Amazing treatments
“Great doctor, amazing treatments.”

Optional upgrade

Want more than a great doctor?

Concierge membership is an optional layer on top of your insurance-based care — same-day access, unhurried visits, and direct messaging with Dr. Hashemi. You never need it to be seen here.
