Personal Interests

I have been happily married for 32 years and have 2 children. My wife and I were both leaders in the Boy and Girl Scouts of America for 20 years. We were involved in backpacking trips including Philmont Scout Ranch. We were also very active in the schools as both are children participated in marching band among other things. In my youthful more vigorous days, my medical school roommate got me into jogging and we did complete the Boston Marathon but don’t ask me what my time was.


Dr. Robert Allen received his Bachelor of Science degree at the University of Notre Dame and proceeded to Jefferson Medical College in Philadelphia for his M.D. His residency in Internal Medicine was completed at Wilmington Medical Center (which has become Christiana Hospital). While in medical school, Dr. Allen was on a Public Health scholarship for 3 of the 4 years, so he ended up joining a practice in Pocomoke City, Maryland – which was an underserved area. The following year we added an office in nearby Salisbury. This was done for the purpose of keeping admitting privileges at Peninsula Regional Medical Center since one of the physicians had to always be within 30 miles of the hospital to cover emergencies.

After fulfilling his Public Health obligations, Dr. Allen continued working at both offices for many years. When HMO’s hit the scene and hospitals were starting their own primary care offices, his practice was concerned that they would be unable to compete on their own. He and his physicians eventually sold their practice to Genesis Health Services. At that time Genesis Health Services had a similar idea to develop a big medical group to try to get the whole package to make their own deals with the insurance companies. Unfortunately, like the hospitals, Genesis Health Services was losing money and eventually Dr. Allen’s practice was let go.

For the last 10 years, Dr. Allen has been back in a private group practice in Salisbury. Also, after 25 years working in the hospital, Dr. Allen gave up his admitting privileges.
