We are pleased to have with us Ms. Diane Williams, PA-C who has been working with me and my staff since February 2004.

Below, you will find general information on Physician Assistants and their role in the dermatology office, as well as specific details of Ms. Williams' background and training.
David F. Jaffe, M.D.

A certified physician assistant (PA-C) is a medical provider who is formally trained in primary care medicine, having graduated from an accredited academic training program in the United States. Ms. Diane Williams, PA-C graduated from the Physician Assistant Program at Essex Community College in Baltimore, Maryland in 1998 and then went on to earn a Master of Physician Assistant Studies (MPAS) in 2002 from the University of Nebraska Medical Center.

Physician assistant training is modeled after medical school training and involves 12 months of full-time classroom learning, followed by 12 full months of on-sight supervised clinical training in a variety of medical disciplines, including dermatology.

Prior to entering the medical field, Ms. Williams earned a B.A. degree from Georgetown University and a Master of Divinity degree from the Washington Theological Union. While working in the area of adult religious education, she began to explore her interest in medicine by volunteering at community health centers and clinics for the homeless.

Ms. Williams' medical education did not stop with graduation. In order to remain nationally certified, shel completes 100 hours of Continuing Medical Education (CME) every two years, and is required to pass a national re-certification exam every six years.

While approximately half of all physician assistants nationwide work in primary care, the remainder practice in many other medical and surgical specialties, including dermatology.

Physician assistants have been practicing with dermatologists for over twenty years, providing a wide variety of services including physical exams, diagnosis, prescription writing, ordering and interpreting lab tests, performing biopsies, cryosurgery, suturing, and medically or surgically treating a wide variety of clinical conditions. As with all physician assistants, dermatology PAs are legally and ethically bound to practice only under the supervision of their employing physician.

Ms. Williams spent the first six years after PA school working as a family medicine physician assistant in a federally-funded community health center in Lancaster, Pennsylvania. Upon returning to her home state of Maryland, Ms. Williams began working with David F. Jaffe, MD, a board-certified dermatologist in Havre de Grace, Maryland.

In addition to her physician assistant training, Ms. Williams has been trained in dermatology under the direct supervision of Dr. Jaffe. She has furthered her education through professional lectures and seminars, attendance at American Academy of Dermatology educational meetings, and Society of Dermatology Physician Assistant conferences. Additonally, she remains up-to-date on the latest dermatologic advances through journal reading and internet-based professional self-study programs.

Along with Dr. Jaffe, Ms. Williams treats a wide range of dermatology conditions in our office. She is thoroughly trained in performing biopsies and treatment of most common skin disorders. She is well-versed in pre-cancer and skin cancer detection and management. Additionally, Ms. Williams has special training in the treatment of acne, rosacea, warts, and laser treatment of psoriasis.

Ms. Williams is a member of the following professional organizations:

Society of Dermatology Physician Assistants
American Academy of Physician Assistants
Maryland Academy of Physician Assistants

More information about Physician Assistants can be found from the American Academy of Physician Assistants (www.aapa.org), and information about PAs in dermatology can be obtained from the Society of Dermatology Physician Assistants (www.dermpa.org).

You may rest assured that your care continues to be managed by me and that Ms. Williams and I work closely as a team to take care of all of your dermatologic concerns.
