Dr. Justin Porter
Board-Certified Pain Management Specialist

Justin Porter was raised in Norman, OK. His achievements in the classroom and on the soccer field earned him a full scholarship to Davidson College in North Carolina. He continued to excel in both arenas: graduating with honors and leading the soccer team as a captain, four-year starter, All-Conference selection, and winning a conference championship his senior season. He was awarded a graduate scholarship through the NCAA’s Southern Conference to attend medical school back home at the University of Oklahoma.
He is passionate in caring for his patients and continuing to build OPM into the best version of itself. He is, however, quick to highlight that the strength of this practice comes from the hard work, dedication, and compassion from its incredible staff members. He enjoys life to the fullest, working hard and playing hard at every opportunity. He is most proud of his home team: his lovely wife Peyton and children Brooks and Caroline.

Dr. Garrett Wright
Board-Certified Pain Management Specialist

Dr. Wright was born and raised in Shawnee where he was a standout baseball player attending college on a full ride athletic scholarship. He had aspirations of playing in the major league before turning his attention to academics and was then able to be accepted to medical school before ever receiving a bachelors degree.
He completed his training in 2016 and joined Oklahoma Pain Management and shortly thereafter became the youngest physician in the country to be trained and certified to offer DRG stimulation; an advanced method of delivering electrical stimulation to nerve roots to alleviate pain.
