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.
