About Dr. John

Philosophy of care

My philosophy of care is to give all patients the same quality of treatment that I would want for a loved one. I strive to treat all patients with respect and provide the best medical treatment possible with modern medicine.

Why I entered medicine

I was inspired to enter medicine because at an early age I recognized I enjoyed science more than any other field. I was particularly interested in neuroscience and wanted to be in a field where I could apply this knowledge to making patients healthier. Neurology was an easy choice because I could have an intellectually stimulating and personally gratifying career.

Community involvement

I support Penn State childhood cancer fundraising, as well as participate in local church philanthropy and service efforts.

Personal interests

When I am away from work, I enjoy Philadelphia sports, traveling, and spending time with family.

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.
