Internal Medicine

John Allen, MD is returning to the Internal Medicine department after serving four years as a Hospitalist at St. Charles seeing Summit Medical Group and HLHC patients. He played an important role in establishing the current Hospitalist program of Summit Medical Group and looks forward to returning to the clinic setting where he can build a more continuous relationship with patients, and help direct their healthcare needs.

Dr. Allen graduated with honors in Biochemistry from Texas A&M University and attended medical school at University of Texas Health Sciences Center San Antonio. He completed his residency in Internal Medicine at the UTHSCSA and board certified in Internal Medicine.

Dr. Allen enjoys all aspects of Internal Medicine and believes good primary care and accessibility can reduce illness and hospitalizations. He sees himself as a patient’s guide in the medical process, be it dialogue, consultations, testing, and/or treatment.

“Helping patients get on the correct diagnostic track and achieve successful results can be very rewarding!”

Outside the office Dr. Allen enjoys his family time along with outdoor sports.
