About Quarry Premier Medicine

At Quarry Premier Medicine, I believe healthcare is most effective when it is personalized, proactive, and built on strong physician-patient relationships. As your internal medicine physician, I take the time to understand your medical history, lifestyle, health goals, and risk factors so we can create a plan that supports your long-term wellness. By combining traditional preventive care with comprehensive testing and deeper health insights available through the MDVIP Wellness Program, we can work together to develop personalized strategies focused on nutrition, fitness, sleep, stress management, and overall health optimization.

My years practicing hospital medicine reinforced an important lesson — many serious health conditions can often be reduced or prevented through early intervention and proactive care. This experience continues to shape my approach to medicine today, with a strong emphasis on preventive healthcare, cardiometabolic health, hormone optimization, weight management, and helping patients stay healthier throughout every stage of life.

As an MDVIP-affiliated practice, Quarry Premier Medicine offers a more personalized care experience with conveniences designed around patient needs. Patients benefit from same-day or next-day appointments whenever possible, minimal waiting, longer visits when needed, and enhanced communication outside of traditional office hours. Whether you have an urgent concern, medication question, or need support while traveling, our practice is designed to provide greater access and continuity of care.

Quarry Premier Medicine proudly serves patients throughout the greater Baltimore area, including Hunt Valley, Lutherville, Cockeysville, Timonium, Monkton, and surrounding communities.
