Resident Physicians

Thomas Frauenhofer

Thomas F. Frauenhofer Jr., D.O.

As a graduate of the Alabama College of Osteopathic Medicine, Thomas chose to specialize in Emergency Medicine as this specialty allows physicians to care for virtually anyone, anytime, anywhere. During residency, Thomas developed an interest in Pain Medicine given his first-hand experience with the opioid overdose epidemic. He believes emergency physicians are uniquely positioned to lead the decrease in utilization of opioids for a more multi-modal pain management approach. He is pursuing a Pain Medicine fellowship to further understand how emergency physicians’ care of acute pain can have an important and lasting impact on patient outcomes.


Amblessed Oneyma, MD

Amblessed is a first year Emergency Medicine resident, originally from Atlanta, GA. She attended the Morehouse School of Medicine in Atlanta and chose to specialize in emergency medicine because she loves being able to make a tangible difference in her patients’ lives, intervening to turn things around at critical times. Pain management is often one of the most difficult aspects of patient care and she is a great proponent of the multimodal approaches advocated by the PAMI program.
