San Francisco, CA and New York, NY -

Gryphon Investors (“Gryphon”), a San Francisco-based private equity firm, and Ares Management, L.P. (“Ares”) (NYSE: ARES) today announced that Gryphon will acquire Ob Hospitalist Group (“OBHG” or “the Company”) from a fund affiliated with Ares. OBHG is the nation’s leading provider of obstetric hospitalist services.

Ares’ fund, along with OBHG founders Dr. Chris Swain and David Swain, will retain a minority ownership position in the Company. Terms of the transaction, which is expected to close in late July, were not disclosed.

Founded in 2006 and based in Mauldin, SC, OBHG is the largest OB/GYN hospitalist provider in the U.S., with a national network of over 550 OB hospitalists serving in more than 120 partner hospitals across 28 states. Through its obstetric hospitalist programs, most commonly providing onsite coverage 24 hours a day, 365 days a year by board certified physicians and featuring an obstetric emergency department (OBED), the company improves the standard of care at partner hospitals for expectant mothers by ensuring consistent and unconditional access to medical care. In addition, as the nation’s largest provider, OBHG is uniquely capable of partnering both with hospitals and the provider community to improve clinical quality, reduce medical risk, and increase the efficiency of the care delivery model.

Ob Hospitalist Group CEO Leonard Castiglione stated, “Our partnership with Ares allowed us to focus on patient outcomes, clinical quality, and operational excellence, which enabled OBHG to expand our customer base and deliver unsurpassed value to our existing customers. We are excited about our new relationship with the Gryphon team and will benefit from their significant resources and expertise to support our clinical mission and growth strategy and further differentiate our value with existing customers.”

Nick Orum, Gryphon’s President and Head of the firm’s Healthcare Group, said, “Gryphon’s investment is the result of a proactive effort over many months to identify market leading companies in hospital-based medicine services. With the support of experienced executive advisors Kevin Blank and Dr. Adam Singer, we quickly recognized the value that OB hospitalist programs provide through more timely, coordinated, and safer patient care, as well as an improved quality of life for physicians. OBHG is a best-in-class company within this growing field.”

Mr. Blank, a member of Gryphon’s Operations Resources Group, will join the board of directors of OBHG’s parent company as Executive Chairman. He has more than 30 years of healthcare operations experience, including in the women’s health area. Dr. Singer, the founder and former CEO of IPC Healthcare, also advised Gryphon and will join the board.

Bennett Rosenthal, Co-Founder and Partner of Ares and Co-Head of the Ares Private Equity Group, said, “We are grateful for the opportunity we had as the financial sponsor of OBHG to partner with the Company’s outstanding management team, visionary founders David and Chris Swain, and Ascension Ventures. We are excited to partner with Gryphon and to continue assisting with the Company’s growth as it pursues its mission of improving women’s health outcomes and saving lives.”
