I believe it is important to work together with you to create a plan of care that's right for you. I will try to be your advocate and help coordinate all of your care needs as your primary care physician. I also have a special interest in geriatrics and long-term care medicine. It is my goal to provide older adults and nursing home residents the highest-quality, compassionate care for optimum health, function, and quality of life. | Why I entered medicine | I became a doctor because I want to make each and every day meaningful, and make a positive impact on your health. I chose internal medicine because it allows me to establish long-term relationships with my patients. I truly enjoy the follow-up care and ongoing relationships I have with my patients, welcoming back the same patients again and again. It is my goal to help manage all of your health care needs - promoting healthy lifestyles, managing chronic conditions, treating illness and coordinating the transition between specialists, hospitals, and other caregivers.

Philosophy of care | I believe that most health troubles can be decreased or solved with a few interventions. Health is optimized when people eat well, are physically active on most days, sleep well, and engage in a community of friends and loved ones. When health is optimized, people can still get sick, injured and die, but they will be better supported through human processes. A good family doctor helps patients optimize their health and is there with them through life and health changes, working to change what we can and accept what we cannot change with dignity. | Why I entered medicine | I always thought I would grow up to be a scientist or some kind of teacher. I tried working in a lab in college, and I found that it lacked human contact.

Philosophy of care | I like to gab with my patients. Good medicine takes time. Each individual is extraordinarily complex. You have a spirit, a personality, societal pressures - all these different factors play a role in a person's health. I try to account for all of it. I think there's an extraordinary untapped potential in the therapeutic value of the patient-physician relationship. I look to release the power of that relationship. In casual conversation, you can learn a lot about someone and share something about yourself. A better relationship means better care for the patient. I'm interested in preventive care – diet, sleep, alcohol, smoking and cancer prevention. For a person to change his or her personal way of life is one of the most difficult things. I ask my patients if they're ready, and then I go as far as I can with them and give them the resources they need. | Why I entered medicine | I was a professional musician – a guitarist. But I soon discovered I was not so musical! I was only able to go so far. Medicine is a DeHoff family tradition.

It's a very important role to play in people's lives. It's more mainstream and more stable than my music career. It also has more opportunities to help people. | Community involvement | I sometimes perform jazz guitar in the Lehigh Valley. | Personal interests | I like a simple life and enjoying the moments of every day.

Philosophy of care | I want to help people live their best life. | Why I entered medicine | My family comes from a combination of cultures.
