Our Team Includes Four People Who Can See You on Short Notice

What are we talking about?

Shorter wait times, high quality dermatology care, a compassionate provider, and accurate diagnosis and treatment are some of the reasons our patients often choose to see a physician assistant (PA) or nurse practitioner (NP). When you have a problem, you want to get it treated quickly. You also want someone who knows your skin and how to get you better. Dr. Moore recognizes this and found a way to help you.

He has hand-picked four individuals as advanced practice providers for his office. Each has gone through highly intensive educational training at DermacenterMD, above and beyond becoming certified PAs and NPs. A typical week would include one hour of educational lecture from Dr. Moore, educational and reading time and proficiency examinations.In addition, they have daily access to Dr. Moore to ask any questions. The training program here is designed to get you rapid access to high quality dermatology care. We also respect those who want to see only Dr. Moore, and if this is you, simply let our scheduling staff know. It does often take a few weeks longer to get in to see Dr. Moore.


What is a Physician Assistant?

 "A Physician Assistant (PA) works in concert with physicians, complementing the physician’s ability to deliver a comprehensive range of medical services. PAs often obtain a bachelor’s degree and must be accepted into a highly competitive 26 month PA training program where they earn a master’s degree in Physician Assistant Studies upon completion. In total, PAs have finished a total of six years of schooling. After completing their training, PA’s work jointly with their supervising physician to hone their skills in their specific field. PAs’ rigorous education, versatility and commitment to individualized treatment help physicians function more efficiently and enhance continuity of health care."

What is a Nurse Practitioner?

"Nurse Practitioners are medical clinicians that hold a master's degree or doctoral degree, and have advanced clinical training beyond their initial professional registered nurse preparation. Didactic and clinical courses prepare nurses with specialized knowledge and clinical competency to practice in primary care, acute care and long-term health care settings. NPs are quickly becoming the health partner of choice for millions of Americans. As clinicians that blend clinical expertise in diagnosing and treating health conditions with an added emphasis on disease prevention and health management, NPs bring a comprehensive perspective to health care. Americans make over 916 million visits to NPs every year."
