About Dr. Stock Keister

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. In medicine, I found the perfect union of science, human contact and teaching, as I work to help each person better understand their bodies and improve their overall feelings of health and well-being.

Community involvement

I am a religious education instructor with the Unitarian Universalist Church of the Lehigh Valley.

Personal interests

I enjoy gardening, reading and going to as many outdoor festivals and carnivals as possible during the summer.

Ratings and Reviews

About Our Ratings and Reviews

About our Survey

Our physicians and advanced practice clinicians (CRNPs and PA-Cs) are among the nation's best. That's why we show you patient satisfaction ratings and comments so you can read about and get to know our providers through the eyes of their patients.

To ensure our ratings and comments come only from verified patients, we work with NRC Health, a third-party organization. NRC Health sends patient satisfaction surveys on LVPG's behalf following an office visit or procedure. They ask patients about their impression of the health care provider and the doctor's or advanced practice clinician's communication skills.

What is included in the star rating?

Star ratings are based on a scale of 1-5 stars, 5 being the best. The rating includes responses to these provider-related questions:

  1. Physician Communication Questions
    1. Did this provider give you enough information about your health and treatment?
    2. Did this provider give you easy to understand information about your health questions and concerns?
    3. Did this provider listen carefully to you?
    4. Did this provider seem to know your medical history?
    5. Did you trust this provider with your care?
  2. Overall Provider Rating Question
    1. Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?

Why don't all doctors or advanced practice clinicians have a rating?

In order to have enough data to measure and compare, a health care provider must have at least 30 completed patient satisfaction surveys. Surveys are included for a period of 12 months from submission.
