We are not accepting new patients at this time

Thank you for your interest in Vein Specialists of Northern California

To My Valued Patients:

It has been an honor and privilege to serve my patients as the Bay Area "Vein Doc" for the past 28 years. As of the end of January 2019, however, I plan to retire and spend time pursuing a long list of interests that have been put on hold during my professional career.

Thank you for the opportunity to be your doctor over the years. I will very much miss you, my staff and my home-away-from-home in the Atrium Building.

Happy Holidays from all of us at Vein Specialists of Northern California!
