Practice Philosophy

The role of the Lankenau Heart Group physician is one of both educator and healer, with the focus to treat each individual patient to improve longevity and quality of life. Not every patient needs to be treated in the same way, and our physicians take the patient’s preference into account when tailoring a personalized course of treatment for them. We believe it is key to listen to our patient and their family members to make sure they have a complete understanding of their cardiac illness as well as their treatment options. For the best possible outcome, it is valuable for both the patient and their family to have a voice in the patient’s care and be invested in their treatment plan.

This doctor is employed by Main Line HealthCare, the multispecialty physician network of Main Line Health, including more than 350 community and hospital-based physicians.
