Led by anesthesiologists Dr. Andrew Messiha and Dr. Joshua Barnhill, the practice focuses on helping people manage pain, improve mobility, and return to daily activities. Its patient-centered approach emphasizes timely access to care, with same-day or same-week appointments often available and many procedures performed at its on-site facility.

The practice also offers care for cancer pain, joint pain, and arthritis, as well as Botox injections for dystonia, ketamine and lidocaine infusions, stellate ganglion blocks, and the MILD procedure. Dr. Messiha has an interest in multimodal pain management and psychological therapies.
