NOTE:  The health and safety of our members is always our top priority. To focus our resources during the pandemic,  we have temporarily changed available services at certain medical centers. Go to kp.org/coronavirus for the latest.

Also, if you haven’t done so already, I encourage you to become a registered user on kp.org so that you can access care while remaining in the safety of your home (kp.org/register).  Whether it is getting mail order prescriptions, having virtual visits, or sending secure messages, our mobile app helps us remain connected at all times, but especially during this critical period.


After completion of my urology residency, I joined West Virginia University Healthcare in Martinsburg, West Virginia as a general urologist and also worked as an assistant professor in the school of medicine. While there, I became proficient in the management of kidney stones given the heavy amount of stone disease in the area. However, I also provided a diverse array of other urologic surgery including minimally invasive and endoscopic procedures.  

I was blessed to have the opportunity to teach medical students and residents in the office and operating room during my three plus years in West Virginia. I was also involved in community education giving several lectures about different aspects of urology.

I also taught high school chemistry at the Hotchkiss School in Lakeville, Connecticut and completed a master's degree in pharmacology and toxicology where I engaged in research in nicotine dependence before pursuing my career in medicine. I have used my years of experience in teaching as a foundation to educate my patients about different disease processes.

I am excited to return to the Washington, D.C. metropolitan area as part of the Mid-Atlantic Permanente Medical Group to continue providing urologic care.
