AND LAURIE RIEBEL MANAGING DIRECTOR OF INSTITUTIONAL BUSINESS

	Columbus, Ohio - December 27, 2011 - Diamond Hill Investment Group, Inc.
(NASDAQ:DHIL) today announced two organizational changes.  Chris Bingaman, CFA

strategy and as CEO of Diamond Hill.  Mr. Bingaman joined Diamond Hill in 2001
and has 21 years of related industry experience.  His primary focus will
continue to be on his role as a portfolio manager.

"As with the addition of Chris Welch as Co-CIO in June 2010, there will be no
change in our shared investment philosophy and process," said Mr. Dillon.
"The CIO role is focused primarily on the external communication of Diamond
Hill's investment philosophy and process, including client-related investment
team efforts and communications.  As always, the portfolio managers are
ultimately responsible for decision making regarding their respective investment
strategy, asset allocation, portfolio construction, and security selection."

Laurie Riebel, CFA was named Managing Director - Institutional Business.  In
this role, she will be responsible for institutional business development,
client portfolio management, and client relations.  Ms. Riebel joined Diamond
Hill in 2007 as a client portfolio manager.  Previously, she worked at
Nationwide Insurance where she served in a variety of roles within the Office
of Investments, including fixed income analyst and portfolio manager.

"Our organizational structure continues to evolve with the growth in our
institutional business as institutions and consultants find value in our
long-term, intrinsic value investment philosophy and process.  Providing a high
level of client service and building lasting relationships has always been part
of our vision at Diamond Hill, and Laurie has proven to be a capable leader in
servicing our institutional clients," said Mr. Dillon.

This evolution in organizational structure will benefit Diamond Hill's clients
by establishing depth within the organization and taking advantage of the
unique talents of each individual through expanded responsibilities.
