This week, we’re proud to spotlight one of our most dedicated physicians, Dr. Thomas Allen.
Dr. Allen is a board-certified emergency medicine physician with more than 20 years of experience in high-acuity emergency and trauma care. He completed medical school at Oregon Health & Science University (OHSU), before returning to Texas to complete his emergency medicine residency at UT-Hermann Hospital.
Throughout his career, Dr. Allen has worked extensively in major trauma centers and has held leadership roles as Medical Director for both a Level II Trauma Center and an air ambulance service. At Advance ER, he also brings a strong focus on longevity medicine and proactive health strategies.
This month, Dr. Allen was honored as our Community Partners of Dallas donor physician, supporting Advance ER’s backpack initiative for children who have experienced abuse and neglect — a cause that reflects his deep commitment to caring for both patients and the community beyond our ER walls.
Dr. Allen has lived in McKinney, Texas for the past 16 years and maintains a ranch in Howe, Texas, where he enjoys driving a tractor, raising animals, and hopes to start an organic garden. He has been married to his wife, Alisha, for 23 years has a daughter, Cameryn, who is preparing to head off to college. Outside of medicine, Dr. Allen enjoys basketball, scuba diving, hiking, fishing, and spending quality time with family.
Thank you, Dr. Allen, for your many years of service. Your leadership, compassion, and unwavering dedication to our patients and staff truly make a difference every day.
When your medical emergencies can't wait until morning and the emergency room wait is hours long, visit Advance ER for emergency medical care in Dallas.
