Anesthesiology Associates

What Anesthesiology Associates does

Anesthesiology Associates, Inc. is a physician-owned anesthesiology group practice founded in 1966 and headquartered in Sioux Falls, South Dakota. The practice delivers comprehensive perioperative anesthesia care—including preoperative evaluation, intraoperative anesthesia administration, and postoperative pain management—across five hospitals and surgery centers in the Sioux Falls metro area: Sioux Falls Specialty Hospital and four Avera Health system facilities (Avera McKennan, Avera Heart Hospital, Avera Specialty Hospital, and Avera Behavioral Health Hospital). Care is delivered via an Anesthesia Care Team model in which board-certified anesthesiologists establish the anesthetic plan in a preoperative interview and supervise Certified Registered Nurse Anesthetists (CRNAs) during surgery.

The practice's clinical capabilities span local, conscious sedation, regional, and general anesthesia, supported by sophisticated intraoperative monitoring. The workforce consists of 25+ anesthesiologists, all Board Certified or Board Eligible through the American Board of Anesthesiologists, with many holding fellowships in critical care, obstetric, pediatric, cardiac, neuro anesthesia, or pain medicine. Patient-facing digital services are limited and operational: an online bill payment portal through SimplePay, a Financial Hardship Program (≤200% of Federal Poverty Level), Good Faith Estimate deliverables under the No Surprises Act, and a patient education website covering anesthesia types, safety, and the preoperative interview.

The business model is fee-for-service professional services billing for anesthesiologist fees, which are invoiced separately from hospital charges. Patients are acquired through referrals from affiliated surgical facilities rather than through direct marketing. The practice is exclusively regional (South Dakota), has no disclosed parent company, is not PE- or VC-backed, and shows no evidence of capital events, M&A, or leadership changes in the source material.

Scale indicators3 records

Recent moves3 records

Broad incumbents

• HCA Healthcare: Large national hospital and surgery center operator that contracts with anesthesia groups for perioperative coverage. Indirectly comparable as the counterparty that drives demand for the practice's services, and a potential consolidator/competitor if it expands in the region.
• Envision Healthcare: Major national physician services company with an anesthesiology footprint serving hospitals and ASCs. Similar exclusive-contract model with hospital systems, though Envision operates broadly across emergency, hospitalist, and anesthesia services and has undergone recent restructuring.
• Sound Physicians: National physician services and practice management company. Comparable in operating exclusive contracts with hospital systems for specialty physician coverage, though its primary focus is hospital medicine rather than anesthesia specifically.
• TeamHealth: Large, diversified healthcare staffing and services company that historically operated an anesthesia division serving hospitals nationally. Comparable in anesthesia service delivery, but operates across many service lines and is far larger and more geographically distributed.

Direct peers

• NorthStar Anesthesia: Multi-state anesthesiology management and staffing company serving hospitals and surgery centers. Closely comparable model: exclusive facility contracts, physician + CRNA care teams, and regional density strategy — though it spans multiple states rather than a single metro.
• US Anesthesia Partners: National, PE-backed anesthesiology group practice that partners with hospitals and ASCs to deliver anesthesia services. Directly comparable business model (physician group + CRNA care team + exclusive hospital contracts), but operates at national scale with roll-up M&A strategy.

Others

• Surgery Partners: Owner and operator of ambulatory surgery centers (ASCs) that contract with anesthesia groups like the subject company. Comparable ecosystem participant and potential customer/partner as ASC surgical volumes migrate out of hospitals.
• Avera Health: Regional health system and the practice's largest customer (four of five affiliated facilities). Material counterparty relationship: Avera's strategic decisions on anesthesia sourcing directly determine the practice's revenue trajectory.

Regional players

• Anesthesia Service Medical Group: Long-established physician-owned anesthesiology group serving multiple hospitals and surgery centers in Southern California. Closely comparable in being a physician-only group with multi-facility exclusive contracts, but serves a different and larger metropolitan market.
