Dr. Jonathan Chin, the founder of Excelsior Pain Management, grew up in Austin, TX, and even though his medical expertise has taken him around the country, he has always identified as a proud Austinite. Dr. Chin graduated with high honors from the University of Texas at Austin and later graduated from medical school at the University of Texas Southwestern Medical Center at Dallas.
Following medical school, Dr. Chin moved to Houston and completed his residency in Anesthesiology at Baylor College of Medicine, which is consistently ranked as one of the best Anesthesiology programs in the country. Desiring further subspecialty training, Dr. Chin was selected among thousands of applicants to complete a Pain Fellowship at the prestigious Harvard Medical School’s Brigham and Women’s Hospital, a program that is ranked the #1 Pain Fellowship program in the country by both the American Pain Society and the American Academy of Pain Medicine.
While at Harvard, Dr. Chin cultivated a passion for treating chronic pain patients – training under some of the pre-eminent pioneers and thought-leaders in the field of Pain Medicine. During this time, driven by a desire to innovate and improve pain outcomes for patients, Dr. Chin also worked on an FDA-approved multi-center clinical research trial to develop and test a novel, non-opioid pain medication.
After graduation, Dr. Chin returned to the Austin area of Texas to serve as an Assistant Professor in the Department of Anesthesiology and Pain Medicine at Texas A&M medical school through a local hospital, where he spear-headed studies to improve pain outcomes in patients with Painful Diabetic Peripheral Neuropathy, and to improve pain outcomes as well as sensory and motor deficits in patients with Spinal Cord Injuries.
Due to his passion for excellence in delivering pain treatments, Dr. Chin founded Excelsior Pain Management. He knew that starting his own clinic would be the only way to ensure his patients received the highest level of personalized care. It is his goal that the training he received from the top institutions in the world, coupled with his passion and care, will help him treat his patients’ wide spectrum of pain conditions – no matter how chronic or debilitating they may be. His mission is to ensure that every patient is treated with kindness, dignity, and the most cutting-edge therapies for chronic pain.
Dr. Chin’s current clinical interests include the use of Neuromodulation, Spinal Cord Stimulation, and Dorsal Root Ganglion Stimulation to treat various otherwise treatment-refractory pain conditions. Dr. Chin also has a provisionally patented medical device, and with the support of Harvard and MIT faculty, plans to finish development of the device to change the field of pain management for the better.
Outside his clinic, you can find Dr. Chin with his wife and family enjoying all Austin has to offer. As a prior NCAA athlete and member of the Texas Crew at the University of Texas (Go Longhorns!), he still enjoys rowing and sports. He loves serving his church community and is an active church member in the Diocese of Austin.
