Dr. Thomas Grace, Clinic Director

tg1Thomas Grace received a Doctor of Chiropractic degree from the University of Western States (UWS)(2015), a BA in Sociology from Gordon College in Wenham, MA (1993) and a BS in Geology from State University of New York and the University of Wyoming (2001).

During his Chiropractic training, Thomas’ love for treating under-served communities led him to clinic rotations with Volunteers of America and a UWS mission trip with Clinica de Mariposa to Costa Rica in 2015, where he treated hundreds of local patients in the San Jose area. Upon his return to the States, he joined Dr. Popovicks at Orofino Wellness Center in Idaho for a final clinic rotation.

Thomas is passionate about non operative spinal decompression and restoring function with the least invasive means possible. Dr. Grace believes that many patients with severe pain and decreased function could avoid surgery and epidural injections with a non-invasive spinal decompression program.

Thomas’ interest in cranial work began twenty years ago by listening to Dr. James Jealous DO lecture on CSF and cranial sacral therapies and has evolved through study and many hours of practice. He has recently completed his certification in SOT (sacral occipital therapy) and enjoys integrating this work into the treatment of his patients at Natural Pain Solutions.

As a clinician, Dr. Grace has a strong interest in functional evaluation and individualized treatment plans. His treatment approach uses a combination of Diversified Adjusting, Activator technique, IASTM, muscle energy techniques, nutritional and cranial sacral therapies.

Thomas’ health care philosophy was shaped by a childhood of simplicity. He was raised without electricity in a log cabin in upstate New York with a work ethic formed by daily wood chores and homework done by candlelight. As an adult, Thomas travelled to Colorado, where he became enamored with mountaineering and eventually became a rock and mountain climbing guide. Ten years of this work took Thomas to every corner of the country as well as up the Nose of El Capitan. He has held teaching certifications in both New York and California, which allowed him to bring his love for learning into the classroom. In more recent years, family became Thomas’ primary focus and that has provided him with unprecedented fulfillment.

Dr. Grace has many hours of postgraduate education in orthopedics, neurology, biomechanics, cranial – sacral, physical medicine and therapeutics and clinical nutrition; as well as diagnostic imaging MRI and CT scan.
