 AMERICAN DENTAL PARTNERS NAMES KEVIN TREXLER AS NEW CEO  –

GREGORY SERRAO TO BECOME EXECUTIVE CHAIRMAN

 WAKEFIELD, MASSACHUSETTS – July 27, 2015 – American Dental Partners, Inc. today announced that its Board of Directors has appointed Kevin Trexler as Chief Executive Officer of the Company, effective July 27, 2015.  Mr. Trexler was also elected to the Company’s Board of Directors.  Mr. Trexler succeeds Gregory Serrao, the founder of American Dental Partners.  In connection with the CEO transition, Mr. Serrao will also cease to serve as President of the Company, but will continue as a member of the Company’s Board of Directors and assume the role of Executive Chairman, effective July 27, 2015.

 “Kevin Trexler brings strong leadership to the Company.  I am excited to see where someone with his extensive patient-centric healthcare experience and fresh perspective will take American Dental Partners in the years to come,” said Mr. Serrao.  “My intention when I founded the Company 20 years ago was to build an enduring organization that would not only survive, but thrive, long after I had moved on.   When I made the decision to transition to a new role within American Dental Partners, we sought out a healthcare executive with experience in a patient-centric model to lead the Company.  Perhaps more importantly though, we also looked for someone with the humility and passion necessary to commit to and flourish within that enduring organization model.  Kevin has impressive healthcare credentials and solid business acumen, but his character is what truly stands out about him.  I anticipate and look forward to great things for the Company under his leadership.”

Mr. Trexler joins the Company from DaVita Healthcare Partners, Inc.  Mr. Trexler had been employed by DaVita in various roles since 2006, most recently as Senior Vice President of Operations, in which capacity he had oversight of and responsibility for more than 700 dialysis clinics.  Prior to DaVita, Mr. Trexler served as a Lieutenant in the U.S. Navy.  He holds a B.S. in Mechanical Engineering from the Massachusetts Institute of Technology, an M.A. in Political Science from the University of Virginia, and an M.B.A. from Harvard Business School.

“American Dental Partners is a tremendous organization with a rich, vibrant culture and a commitment to patient-centric dental care,” said Mr. Trexler.  “The Great Recession brought about a ‘new normal’ in the dental industry.  Where others may see challenges though, I see opportunities.  I believe that our patient-centric, multi-disciplinary approach to dental care positions us well to solidify and grow our leadership position within the marketplace for dental services.  I also believe that our choice of dental group partners gives us a distinct advantage in the marketplace.  These are exceptional dental professionals who understand that only by placing the needs of the patient first can our collective organization achieve it strategic goals.  Together with our partners, we have a bright future ahead of us.  I appreciate the trust that has been placed in me as Greg’s successor.  He truly has created an enduring organization that has both advanced and transformed group practice within the dental industry, and I hope to continue and build upon his legacy as steward of that organization.”

In his new role as Executive Chairman, Mr. Serrao will seek to ensure the successful transition of the CEO  role to Mr. Trexler.  He will provide mentorship and guidance to Mr. Trexler based on the experience and knowledge he has gained serving as the Company’s CEO and President for the past two decades.  Additionally, Mr. Serrao will chair the Company’s Board of Directors and work on strategic initiatives for the Company, such as acquisitions, public policy and regulatory affairs.
