DR. STEPHEN RITTERBUSH
In December 2016, Dr. Ritterbush retired as the Managing Partner of Fairfax Partners, a Washington, D.C. based equity firm, which he founded in 1989. During his career Dr. Ritterbush had been responsible for approximately 40 private equity investments that were a combination of both leveraged buyout/acquisition-oriented transactions and more traditional early-stage venture capital opportunities. Over the last 18 years, Dr. Ritterbush has also founded or co-founded more than 25 companies.
From 1989 to 1991, Dr. Ritterbush was President and CEO of Greater Washington Investors, a $38 million Small Business Investment Corporation (SBIC), where he repositioned a stagnant, underperforming portfolio, ultimately resulting in an eleven-fold increase in the share price.
In 1986, Dr. Ritterbush, with five partners, successfully acquired Kaiser Engineers, of Oakland, California. Kaiser Engineers was then merged with ICF, a northern Virginia company of which he was a partner. In the newly merged companies, he served as a director and senior corporate officer of ICF Kaiser International, Inc., and President of its subsidiary, American Venture Investments, Inc. During this period, ICF’s revenues grew from $18 million to more than $500 million, as the company became one of the largest environmental engineering and remediation firms in the United States. In 1989, the company was taken public by Alex Brown.
From 1981-1986, Dr. Ritterbush served as President and Chief Executive Officer of Arthur D. Little Far East, Inc., located in Singapore. While in the Far East and later in Washington, DC he worked with Advent International of Boston, MA to establish and develop venture capital funds in Singapore, Hong Kong, and Malaysia.
Dr. Ritterbush received a BS in civil engineering and a BA in political science from Union College. He subsequently earned an MS in oceanography from the University of Hawaii as well as an MA in international affairs and a PhD in international economics from the Fletcher School of Law and Diplomacy of Tufts University. He was concurrently awarded a Rockefeller Foundation Fellowship to support further study at the Belfer Center for Science and International Affairs, John F. Kennedy School of Government, Harvard University.
Dr. Ritterbush served on the Board of Trustees of Union College and as Chairman of the Finance Committee for eleven years from 2005-2016. Until 2019 he served as Chairman of the Board of Advanced Software Systems (Assyst) of Sterling, Virginia. He is currently the founder and equity owner of two early-stage companies: xMD Diagnostics, which develops medical equipment for the emerging field of genomics, and Cordex Systems, Inc., a medical device company that is developing a new non-invasive way to examine inflammation in a patient’s arteries.
