About Dr. Hernandez

Philosophy of care

Injuries to the upper extremity (hand, wrist and elbow) are of societal concern because they affect individuals’ ability to function at work or play. Restoration of function is my primary goal, and I make sure to tailor the treatment to your individual needs. My training has provided me great perspective on the various treatment options and when to apply them. For 18 years I have had the honor of providing patients orthopedic care of the upper extremity, including trauma, reconstruction and microvascular repair.

Why I entered medicine

I entered medicine because of sports. Spending time in the training rooms as a teenager and young adult recuperating from sports injuries introduced me to musculoskeletal anatomy, which I found fascinating. I deepen my understanding of musculoskeletal anatomy, injuries and treatments through my professional practice experience as well as organizations such as the American Society for Surgery of the Hand. Patient education is central to an optimal outcome, whether the issue is carpal tunnel surgery or more complex reconstructive procedures.

Personal interests

Family and community are of great importance to me. In addition to my work, friends and family, I enjoy all the outdoor activities the Lehigh Valley has to offer, including golf and snowboarding. I have a passion for woodworking, especially using locally reclaimed materials to build furniture, doors, stairs etc.

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.
