Dr. James Freidenstein

Dr. James Freidenstein

Dr. Freidenstein grew up in Memphis, Tennessee. He obtained his medical degree from the University of Tennessee, where he graduated with highest honors and was a member of the Alpha Omega Alpha honor society. During his medical training, he completed research programs at St. Jude Children’s Hospital, as well as with the American Society of Hematology. He went on to complete his residency in anesthesiology at the Mayo Clinic.

A heavy emphasis on acute post-surgical pain, regional anesthesia, and nerve blocks prompted Freidenstein to develop a keen interest in pain management. He found that being able to help ease the burden of chronic pain for his patients was extremely rewarding. Because of this, he decided to pursue a career in fighting the underlying sources of refractory pain.

He later completed his fellowship in interventional pain management at the University of Alabama at Birmingham. He studied under the leading researcher in the field of arachnoiditis. During his fellowship, he published research about perineural cysts and their treatment. Following his fellowship, he stayed on staff at the UAB anesthesia department and helped to manage acute inpatient pain.

Dr. Freidenstein is board-certified in both anesthesia and pain management and is involved with national and local interventional pain societies. His particular interest is in post-surgical spinal pain and alternative modalities for fibromyalgia-mediated pain.

He enjoys most outdoor activities and spending time with his 6-year-old twins.

Dr. Adam Cartwright

Dr. Adam Cartwright

Dr. Cartwright is an anesthesiologist and fellowship-trained interventional pain physician. He received his medical degree from the University of Tennessee Medical School, where he was inducted into the Phi Chi medical fraternity and received the Dorothy Snider Scholarship. He went on to complete a residency in anesthesiology at the Mayo Clinic in Jacksonville, Florida, where he served as the chief resident.

He went on to complete an interventional pain fellowship at the Mayo Clinic in Rochester, Minnesota, and transferred to the Mayo Clinic in Jacksonville to serve as a staff physician.

Dr. Cartwright has presented at several national meetings and has been actively involved in several research projects. His primary passion, however, continues to be patient care and education of the medical community, focusing on options in pain management. His particular interest center around objective evidence-based medicine as it relates to spinal interventions.
