Hi all, my name is Bryanna and I was raised right here in Sunnyvale! I had the pleasure of joining the Lew Crew in 2016 and have really enjoyed the family environment between our awesome staff and all our amazing patients. Outside of the office you can typically find me hanging out with my friends, family and dog/cat or on an outside adventure.

Hi, I’m Frank – When you enter the office, you might see a guy in a “Quickbooks overload” trance….that would be me. But I love working in an office which feels like an extended family and we hope that you all feel that warmth as well. By the way, GO NINERS, GO DUBS, GO GIANTS, GO SHARKS!!!

Michelle - Meet Our Team


Hello, my name is Michelle! I’m so lucky to have recently joined this wonderful office in 2021. I was born and raised just off the coast in Monterey County. Some of my favorite things to do are travel and read. I love to do both as much as I can, but the best is when I can read while I travel.
