Ronald Kass, M.D. Inc., MPH, D'ABSM


  • 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.
