Family MedicineLanguages:
EnglishI am a board-certified family medicine physician who provides comprehensive, patient-centered primary care to individuals of all ages. As a former industrial engineer who worked in the aerospace industry, I like to understand the details of how complex systems work, and then develop solutions using the latest evidence and research. I carry this approach into my medical practice by understanding the unique complexities of each patient and then creating a personalized evidence-based treatment plan. I help my patients navigate the healthcare system by coordinating their care among various medical specialties and following them closely through any hospitalizations, surgeries or illnesses. I am proactive in providing health screenings and lifestyle coaching to prevent illnesses and to help each of my patients live their healthiest life. Some of the more common conditions that I treat include hypertension, obesity, diabetes, depression and sports-related injuries.
Prior to joining St Luke’s Quakertown Primary Care, I completed my residency training in family medicine at St Luke’s Warren Hospital. I completed my undergraduate degree at Cornell University, where I studied industrial engineering and played on the squash team. I then worked in the aerospace industry and earned my MBA from Seattle University. I transitioned my career to medicine and attended the University of Pennsylvania for my premedical studies, followed by medical school at Drexel University.
In my free time, I enjoy tennis, squash, skiing, traveling and playing the piano. I live in Philadelphia with my wife, where we enjoy walking in the local parks.
