Also, if you haven’t done so already, I encourage you to become a registered user on so that you can access care while remaining in the safety of your home (  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.

I chose to practice at the Mid-Atlantic Permanente Medical Group because I believe in its philosophy that embodies total health and wellness for patients and the staff who treat them.

I am passionate about patient safety. My area of expertise is pediatric anesthesiology, but I also enjoy OB anesthesia and adult patients.

Caring for body, mind, and soul is the way I practice. Since many patients are anxious before procedures, being a reassuring presence goes a long way in allaying their fears. As Francis Peabody said in 1925 "...the secret of the care of the patient is in caring for the patient." I strive to live by this principle every day.
