"Philosophy of care | My philosophy of care is patient-centered. I believe in a strong doctor and patient relationship that involves mutual respect, honesty, compassion and personal responsibility. I believe an essential part of ""doctoring"" is providing quality medical care in a caring atmosphere where every patient is heard and treated as a unique individual. | Why I entered medicine | Ever since I could remember I had always wanted to go into medicine. I am one of seven children. My mother was a nurse and she always encouraged me to enter the medical profession. She entered nursing school when I was 8 years old. I was brought up watching her study, listening to stories about patients and the hospital. My enthusiasm for medicine continued in high school and college; I loved the sciences. When it was time to fill out my application, I knew being a doctor would enable me to make a positive and meaningful difference in the lives of people when they need it most, and there are not many professions that give us that privilege. | Community involvement | I remain active in the community supporting my church, childrens schools and sports teams. I am also active in the American Heart Association's Lehigh Valley chapter. | Personal interests | As a mother of three beautiful children, wife of a wonderful cardiologist and a solo medical practitioner in internal medicine, personal interests are hard to fit in. My father purchased a home on the Jersey Shore in 1994, which allows me to enjoy the beach and precious time with my family. I also love to ski. I started skiing in medical school and make a yearly trek out West with my family and friends.

Philosophy of care | I’m a primary care physician, so I treat the patient as a whole and address all needs, whether physical, mental or social. Specialists such as cardiologists may specifically treat the heart, or pulmonologists may treat the lungs. Primary care physicians treat the whole body from top to bottom. We identify the nature of the problem and address it or, if called for, are able to refer a patient for more specialized care. I enjoy what I do because I like to help patients and prevent diseases before they start. | Why I entered medicine | I wanted to help people and I like to interact face-to-face, so I always had a passion for medicine. It’s rewarding to help someone directly with my skills, mind and know-how, so to speak. And I like the long-term relationships that come with primary care. I treat people from ages 16 to 90 or even 100, and I get to know their families and kids. It’s very rewarding to take care of entire families. | Community involvement | I sing in a church choir and am involved in church life. I like to sing and enjoy music in general. | Personal interests | I enjoy skiing in winter and playing soccer in summer. I belong to a recreational soccer league of people above 40. We’ve been playing together for more than 12 years, mostly on weekends. For skiing, I like to go out West to the Rockies.
