The Role of the Physician Assistant/Associate in Our Practice.

Lisa Van Horn MMSc PA-C

Lisa Van Horn, MMSc, PA-C

We are very excited to welcome Ms. Lisa Van Horn to our practice. Ms. Van Horn comes to us directly from Yale University's Physician Associate Program. Though a recent grad,  she is no newcomer to the discipline of dermatology.  She brings with her an extraordinary seven years of preparation in the specialty as a former editor of dermatology texts and the administrator of a Mohs surgery fellowship program.  This unique backgrounding in theory and diagnostics coupled with the fact that she holds an additional master's degree in Clinical Counseling Psychology signaled to us the makings of an unusually gifted provider.  Her experience and training in psychological counseling also means that she views patients from an holistic perspective and is extraordinarily sensitive to the mental, emotional and physical well-being of her patients.   She's warm and down to earth -- a real breath of fresh air, and we are very happy to have the pleasure of working with her.  Ms. Van Horn has completed her fellowship in dermatology with Dr. Saruk and is now accepting patients.
