  • Board Certified in Sleep Medicine
  • Board Certified in Pulmonary Medicine

Born in San Francisco, I have been practicing medicine in Stockton since 1986. I practiced Pulmonary and Critical Care medicine for many years and   started practicing sleep medicine in 2001 and became board certified in 2003 and recertified in 2011.   I enjoy helping my patients to achieve a good quality of sleep. There is an ever growing appreciation of the harmful effects of sleep apnea on common diseases such as hypertension, diabetes, strokes and memory loss.  My satisfaction comes from seeing the appreciation of my patients as they are so happy to be feeling good and able to enjoy their lives to the fullest.

  • Board certified in Internal Medicine
  • Board certified in Sleep Medicine

I grew up in Southern California and moved to the Central Valley in 2012. I worked as a hospitalist for many years and transitioned to Sleep Medicine a few years back. I completed my Sleep Medicine training at Stanford University. One of my greatest joys is helping patients achieve good quality sleep, an important, but often neglected part of one's health. One of my mentors from fellowship said, "Your life is a reflection of how you sleep, and how you sleep is a reflection of your life." My goal is to help my patients achieve the most restful, rejuvenating sleep so that they can live their best lives. I look forward to seeing you in the clinic!

  • Board Certified in Sleep Medicine
  • Board Certified in Internal Medicine

As a Central Valley native, I spent my childhood in Stockton, CA. I completed medical school at Touro University College of Osteopathic Medicine in Vallejo, CA. After graduating, I completed my residency in Internal Medicine at the University of Miami, where I then stayed to complete my fellowship training in Sleep Medicine in 2023. During fellowship, I was fortunate to have amazing mentors who helped me gain a deeper understanding of sleep and its impact on one’s overall health. I am passionate about communicating that knowledge to all of my patients so they can understand the impact that healthy sleep can have on their quality of life and feel empowered to truly optimize their sleep.
