Founder and Chief Executive Officer
Aric Burke
Aric has more than eighteen years of ASC consulting, development, and operations experience. He is responsible for the overall vision and company operations, driving profitability, and the organizational structure and strategy of Atlas.
Prior to founding Atlas, Aric served as the West Market President for United Surgical Partners International (USPI), the largest ASC management company in the industry. As Market President, Aric was responsible for the development and operations of USPI markets throughout the Western US. During his five years at USPI, Aric grew the West Market to over 30 ASCs and three surgical hospitals performing over 150,000 cases annually generating over $450M in net revenue and $90M in EBITDA with more than 2,500 employees. He also worked closely with large not-for-profit health system partners to develop their ASC networks including Dignity Health in Phoenix and Las Vegas, Centura Health in Denver, and Carondelet Health in Tucson.
Prior to joining USPI, Aric served as Vice President of Consulting and Development at Health Inventures, a physician and health system consulting firm that specialized in developing and managing ASCs. While at Health Inventures, Aric worked with some of the largest and most successful health systems throughout the US to acquire and form ASC partnerships in their markets as well as projects to develop ASC and ambulatory facilities in the UK and Middle East.
Aric began his career as a Certified Public Accountant with Deloitte after earning an MS in Business Administration with a focus on accounting, and a BS in Business Administration with a focus on Finance, both from the University of Colorado.

General Counsel
Robert (Bob) Cohen, JD
Bob joined Atlas in May of 2021 after serving as national chair of the health care practice of a large law firm for close to 40 years. He was heavily involved in the founding of Atlas and served as Atlas’ lead outside counsel prior to assuming the role as its General Counsel. As General Counsel, he oversees all legal aspects for both Atlas and the ASCs which Atlas manages. He also handles all ASC acquisitions and syndications.
In private practice, Bob was outside counsel for decades to some of the largest nonprofit health systems in the US. His work on behalf of these systems included handling major acquisitions and affiliations as well as overseeing clinical joint venture arrangements and other physician strategies in multiple areas. For several of his clients, Bob was integrally involved in the planning and execution of physician joint ventures strategies to develop market-wide networks of ASC and other ambulatory services similar to what Atlas now does. Under Bob’s leadership, Atlas approaches its health system partnerships and work on behalf of its nonprofit partners from the perspective of what is best for the health system and what he would negotiate for as health system counsel. This approach begins with partnership documents that assure the controls and protections (e.g., tax exempt status) critical to health systems are a given (and not something to be negotiated for as is typically the case with other ASC companies). Bob works closely on a continuous basis with the General Counsel and in-house counsel staff of our health system partners to assure that the underlying ASC joint ventures are structured in compliance with terms and conditions agreed to with the health system and that the ASCs are managed in a legally compliant manner.
Bob’s decades of transaction experience also allows Atlas to handle ASC acquisitions and syndications on behalf of its health system partnerships in a highly efficient and cost effective manner particularly as to outside counsel expense. Bob is a graduate of The University of Chicago law school.
