Meet Michael Hennessy

Dr. Michael Hennessy is a native Texan through and through. He is privileged to be able to call himself a member of the Sons of the Republic of Texas, and he is proud to call Dallas, Texas his home.

Dr. Hennessy was born in Dallas to a family with three other siblings. He stayed in Dallas for his undergraduate education at Southern Methodist University. He majored in mathematics and graduated summa cum laude and valedictorian of his class. Dr. Hennessy then went on to Georgetown University School of Medicine in Washington D.C. to obtain his medical degree. He graduated cum laude and then was drawn back to Texas when he matched an Orthopaedic surgery residency here locally at The University of Texas Southwestern. It was during his time at UTSW that he met his wife and eventual mother of their three children, Fallon.

After completing the rigorous training program at UTSW and Parkland Hospital, Dr. Hennessy decided to get a little bit more sunshine by completing his spine surgery fellowship under the guidance of Dr. Behrooz Akbarnia in San Diego, California. He knew he wanted to practice medicine back in Texas so he accepted his first position after training at a very well-known Orthopaedic surgery clinic in San Antonio, called The San Antonio Orthopaedic Group. After spending three years in San Antonio, Dr. Hennessy and his wife made the decision to return to his hometown of Dallas and he has been practicing at Texas Spine Consultants ever since. He is very honored to have the opportunity to practice medicine and serve the very community where he was raised.

Dr. Hennessy is a highly accomplished spine surgeon with expertise in treating a wide range of spinal conditions. He serves as a consultant for several companies focused on advancing spine care and has a strong interest in minimally invasive techniques. These include the iFuse Implant System® by SI-BONE® for sacroiliac (SI) joint dysfunction and the Centinel Spine prodisc C Vivo for cervical disc replacement. His dedication to patient care has earned him recognition as a Texas Monthly Super Doctor every year since 2017, as well as being named one of D Magazine’s “D Best” doctors in 2020 and 2024.

Dr. Hennessy is an American Board of Orthopaedic Surgery certified orthopedic surgeon and spinal surgeon and is presently a diplomate of the board. He is a fellow of the American Academy of Orthopaedic Surgery. He also is a member of the North American Spine Society, the Dallas County Medical Society, and the Texas Medical Association.

Dr. Hennessy wants nothing more than to take the utmost care of every single one of his patients in the most conservative and minimally invasive manner.
