About Dr. Yozviak

Philosophy of care

I view my role as a physician as that of a coach. I educate and advise my patients to empower them to become active in managing their own healthcare. I work as a member of a team of physicians, nurses, behavioral health specialists, case managers and many others to better meet our patients' medical, behavioral and social needs.

Why I entered medicine

I have devoted my career to providing the highest quality primary and specialized care to patients with HIV/AIDS, hepatitis C, and/or hepatitis B regardless of their ability to pay. Caring for people living with HIV/AIDS and/or viral hepatitis has allowed me to develop relationships with patients who have wonderful stories and to advocate for them on a daily basis. This field allows me to blend my passions for patient care, clinical research and medical education.

Community involvement

I serve as faculty and a professional development coach for our medical students in the LVHN-USF SELECT MD program. I hope to be able to help guide our next generation of physician leaders to look beyond the requirements of their traditional medical training and develop the skills that will allow them to succeed in a rapidly changing field. I also oversee the Hepatitis Care Center's hepatitis C testing program. We offer free, rapid hepatitis C tests (results in 20 minutes) with a finger-stick sample to anyone in the community who has had a risk for hepatitis C infection at any point in their life.

Personal interests

I enjoy spending time with my wife and children. I have been a passionate Philadelphia Eagles fan for as long as I can remember. I’m lucky to be able to bleed green a few days a year during home games at Lincoln Financial Field.

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.
