Premier, personalized, convenient healthcare and medical concierge services

Our Practice

Truly Personalized Healthcare

Executive Healthcare Services (EHS) was founded in 2004 by co-founders Mark Vasiliadis, M.D. and Kevin Kelleher, M.D. EHS was created as an alternative to impersonalized, inconvenient and fragmented healthcare. Today, our total care management approach is centered on convenience, providing each client with a tailored health plan combined with 24/7 access via phone and email to an EHS physician.

Our practice, is the Greater Washington D.C. area’s leading concierge medical practice offering first-class healthcare services to CEOs, cabinet leaders, celebrities and other VIPs and their families. Whether you need a comprehensive annual physical, immediate treatment for the flu, access to a top specialist or medical coordination around the globe, an EHS membership gives you the peace of mind you deserve.


What Makes Our Practice Different?


Care focused on you — your needs, your lifestyle and all delivered at your convenience. Medicine may be complicated but exceptional healthcare shouldn’t be.


Our ratio is always less than 350 clients per doctor which is 1/10th of traditional offices. This gives us the time to get to know each client, their medical history and provide personalized, proactive care.


Regardless of where you are in the world, our award-winning physicians are just a phone call or email away. Our members enjoy unrestricted virtual and on-site access wherever and whenever they need it.


We go above and beyond in our care delivery and coordination. Whether coordinating a routine appointment to meet your tight schedule, finding the closest pharmacy to the Ritz in London where you are staying for a business meeting, or evaluating travel vaccines and prevention needs for an upcoming Africa trip, our concierge team and doctors deliver. Your care comes first — anytime, anywhere!
