AMSURG History

1986: It all started on a napkin as co-founders David Manning and Rodney Lunn planned the launch of Practice Development Associates (PDA) and consulted on the development of more than 75 ambulatory surgery centers.


1992: AMSURG Corp was created through a capital investment by American Healthcorp and private equity investors from Nashville. AMSURG Corp’s focus shifted from ASC consulting to the development of a single-specialty, equity-partnership model.

1997: AMSURG became a public company listed on the NASDAQ exchange on December 3, 1997, and as detailed in the company’s first Annual Report, “strengthened its position as the undisputed leader in the physician practice-based ambulatory surgery center business.”

1999-2000: AMSURG revenues topped $100 million for the first time, and AMSURG became a leader in ophthalmology surgery centers with its intent to purchase majority ownership of 11 eye surgery centers affiliated with Physicians Resource Group, Inc. (PRG).

100 centers

2002: AMSURG reached a milestone of 100 ambulatory surgery centers.


2007: Chris Holden named AMSURG President and CEO.

2008: AMSURG centers reached one million surgical procedures during a single year, pushing company revenues to more than $600 million.

2011: AMSURG acquired National Surgical Care (NSC), based in Dallas, TX, adding 16 centers to AMSURG’s portfolio. As a result, a separate multispecialty division was established to facilitate growth.

2012: AMSURG added health system development to its portfolio. The development strategy explores and assesses the suitability of partnering with a hospital or health system in a strategic and synergistic approach beneficial to physician partners, the health system and AMSURG.


2014: AMSURG joined forces with Sheridan Healthcare, a leading national provider of multispecialty outsourced physician services to hospitals, ambulatory surgery centers (ASCs) and other healthcare facilities. This acquisition further diversified and differentiated AMSURG by establishing leadership in outsourced physician services while maintaining leadership in the freestanding ambulatory surgery center space.

2016: Envision Healthcare and AMSURG merged, bringing together two leading, complementary healthcare companies to form one of the nation’s largest provider organizations, well positioned to help shape the future of healthcare delivery. Envision Healthcare manages a highly differentiated suite of clinical solutions to support health systems, communities and payors and offers a broader continuum of patient care.

2018: Private equity investment firm KKR acquired Envision Healthcare, adding it to KKR’s portfolio of other healthcare organizations. This transaction made AMSURG a private company for the first time since going public in 1997.
