Vivek Mahendru, MD

CEO & Medical Director

Dr. Mahendru started the first national Residents Section at the American Society for Regional Anesthesia (ASRA) and become a member of the American Society of Anesthesiology Committee on Pain Medicine while he was the Chief Fellow at Brigham and Women’s Harvard teaching institution. After this, he was appointed to lead and chair the CPT advisory committee of the American Academy of Pain Medicine Committee on Pain Medicine and represent the pain management physician community at the American Medical Association Board of Directors meetings.

Dr. Mahendru is an accomplished author and lecturer and speaks, teaches, and volunteers his time in underdeveloped nations in his specialty. He is also a former consultant to the Texas Medical Board.

Given his 25-year history of being a successful Pain Medicine physician, Dr. Mahendru has notable accolades that he is proud of:

  1. He audits, supervises, and manages his providers to provide best-in-class, high-quality care in a cost-effective setting.
  2. He meets with his staff and providers once a month to review quality improvement strategies.
  3. His patients do NOT utilize the ER for after-hours care or for pain management services.
  4. He minimizes and creates an opioid-free environment for his patients.
  5. He does NOT utilize spine fusions as a cure for his patients, therefore, minimizing post-fusion failures in treatments which can be costly to the carriers and patients.

Dr. Mahendru believes advanced technology in a compassionate setting with patient outreach provides good outcomes and results. This is a highly cost-effective approach to achieving best-in-class care with outstanding results. Outcomes are tracked on a quarterly basis to demonstrate this.
