IRVING, Texas -- December 4, 2013

USMD Holdings, Inc. (NASDAQ: USMD), a physician-led integrated healthcare
system, announced today that Emily Isaacs, M.D., a USMD rheumatologist, has
been appointed to serve a three-year term on the American College of
Rheumatology Board of Directors. Dr. Isaacs’ term as director commenced at the
American College of Rheumatology annual meeting in October.

The need for rheumatologists is increasing across the country. According to
the Centers for Disease Control and Prevention, nearly 50 million U.S. adults,
or 22 percent of the adult population, suffer from arthritis; 1.3 million of
those suffer from rheumatoid arthritis. By the year 2030, it is estimated that
67 million adults, or 25 percent of the population, will be diagnosed with
arthritis.

“As the need for rheumatologists and the treatment of rheumatic disease
expands, having representation on the American College of Rheumatology Board
of Directors is a great honor for Dr. Isaacs and USMD,” said John House, M.D.,
chairman and chief executive officer of USMD Holdings. “We’re proud of Dr.
Isaacs and this achievement.”

The American College of Rheumatology represents more than 10,000
rheumatologists and rheumatology health professionals around the world with
the goal of advancing the field of rheumatology, studying and researching
rheumatic diseases and treatments, and educating physicians on the field of
rheumatology so they know when to refer patients for treatment. The American
College of Rheumatology offers its members the support they need to ensure
that they are able to continue their innovative work by offering support for
education, research, advocacy, and practice.

“This is an exciting time for rheumatology and it’s an honor for me to be
appointed to the American College of Rheumatology Board of Directors,” said
Dr. Isaacs. “The need for rheumatologists is increasing as our population
ages. I am excited to join the Board and be given the opportunity to advance
the field of rheumatology, promote educational opportunities for our members,
expose more medical students to the field, and serve as an advocate to help
ensure that patients have access to affordable, quality care and treatments.”

Prior to serving on the American College of Rheumatology Board of Directors,
Dr. Isaacs spent six years on the organization’s Rheumatology Research
Foundation Board of Directors. She served three of those years as chair of the
Development Advisory Committee, where she helped raise more than $43 million
dollars to fund research and training for future rheumatology scientists and
practitioners.
