What is a Doctor of Osteopathy (DO)?

A DO is a Doctor of Osteopathy. Osteopathic Physicians are fully licensed physicians encompassing all specialties in all 50 states. The DO degree is conferred upon physicians in the same manner as allopathic physicians, MD, after completing 4 years of Medical School and residency training. Osteopathic physicians have additional training performing manipulative therapy for spinal ailments.

What is a PA and NP and what can they do in comparison to a doctor?

PA stands for Physician Assistant. A PA has several years of postgraduate training in clinical medicine after a college degree. Our PAs are board certified and take continuing medical education courses every year just like our physicians do.

NP stands for Nurse Practitioner, and they first obtain a Bachelor’s Degree in Nursing and then attend postgraduate training and graduate with a Master’s Degree in Nursing. NPs are also board certified and take continuing medical education courses yearly.

Both disciplines treat patients from the age of 6 years and up for “sick” visits. They also perform Women’s Well Exams, PAP-smears, and Sports Physicals. In addition, the PA performs Adult Well Exams in our office up to the age of 60 years. Both PA’s and NP’s also treat patients in our office for Depression/Anxiety.
