What Associated Anesthesiologists does

Associated Anesthesiologists, Inc. (AAI) is a physician-owned professional corporation founded in 1960 and headquartered in Tulsa, Oklahoma. The company self-describes as the largest anesthesia group in the state and provides a full range of anesthesia services, including general anesthesia, IV sedation (minimal, moderate, and deep), local anesthesia, and obstetric anesthesia covering epidurals, combined spinal-epidurals, spinal anesthesia, and C-section coverage. Service delivery is anchored by a Pre-Anesthesia Testing Clinic staffed by physician assistants that performs preoperative evaluation, clinical testing, and physical examinations to optimize patients prior to surgery. Clinically, AAI operates a team-based anesthesia care model with physician supervision, drawing on 30+ board-certified anesthesiologists with subspecialties in pediatrics, cardiothoracic, pain management, obstetric, and regional anesthesia, supported by 70+ Certified Registered Nurse Anesthetists and Anesthesiologist Assistants, plus 11 administrative staff. The practice administers anesthesia in more than 70,000 procedures per year.

AAI delivers services through embedded contracted teams at five healthcare facilities in the Tulsa area: Saint Francis Hospital, Saint Francis Hospital South, Natalie Ambulatory Surgery Center, Oklahoma Surgical Hospital, and Plastic Surgery Associates. Referrals are generated through its hospital and surgical center partnerships, and the practice bills patients separately for anesthesia services based on procedure length, type, patient health, and any special monitoring requirements. Patients can pay through online portals or pre-pay by phone. There is no disclosed proprietary technology platform; the technology footprint is limited to a practice website with educational content, patient forms, and third-party payment integrations.

Commercially, AAI is a private professional corporation under Oklahoma law, led by President Jeff Lindsay, MD, with an administrator (Janell Crowl, MBA), office manager (Michelle Tolbert), billing manager (Kellye Torres), and HR manager (Marian Russell). The company is physician-owned with no disclosed private equity, venture capital, or parent company involvement, and operates exclusively within Oklahoma. Its competitive position rests on scale (largest anesthesia group in Oklahoma), clinical breadth (no procedural or patient limitations), long-tenured facility contracts, and 60+ years of brand presence in the Tulsa market.

• U.S. Anesthesia Partners (USAP): Largest physician-owned anesthesia group practice in the U.S., founded by anesthesiologists and PE-backed, providing hospital-based anesthesia services nationwide.

• Compass Anesthesia: Regional anesthesiology group practice providing hospital-based anesthesia services. Comparable as a physician-led anesthesia services group pursuing hospital contracts in a defined market.
