               CHIEF FINANCIAL OFFICER, RONALD EZERSKI, TO RETIRE

           Hires Seasoned Executive with Extensive Business Experience

MINNEAPOLIS, July 1, 1999 -- Patterson Dental Company (Nasdaq: PDCO) today
announced the early retirement of Ronald Ezerski, executive vice president and
chief financial officer, effective July 31, 1999. R. Stephen Armstrong, formerly
with Ernst & Young LLP, has been named as Ezerski's replacement.

Ezerski, 53, was a member of the original management group that acquired
Patterson in 1985. He began his career with the company in 1982 as vice
president of finance and as president of its subsidiary, Dental Capital
Corporation. That subsidiary was merged into the company in 1988. In 1997
Ezerski became executive vice president of the company. He was named a director
of Patterson in 1983, and will continue to serve on the company's board.

"Over the past 17 years, Ron has made outstanding contributions in every area to
the development and success of Patterson," said Peter Frechette, chairman and
chief executive officer. "Through his leadership and dedication, he has helped
set the standards for Patterson, playing a key role in building a successful
national company recognized as an industry leader. We are very pleased that he
will continue to contribute his experience and advice as a director of the
company."

"While we are sorry to see Ron relinquish his day-to-day role with the company,
we are very pleased to have a leader of Steve's caliber joining us," added
Frechette. "He brings more than 26 years of management and business skills to
Patterson, and has an established track record for success. As we continue to
expand, Steve's expertise will greatly reinforce our efforts."

Armstrong, 48, spent 26 years at Ernst & Young LLP, an international services
firm, most recently as a senior assurance partner, and served as an advisor to
Patterson for five years during his tenure there. At Ernst & Young, he served
publicly held national and multi-national clients in the consumer products,
manufacturing and service industries, with extensive experience in Securities
and Exchange Commission requirements and reporting, inventory accounting
techniques, acquisition due diligence and reporting, corporate income tax, and
stock compensation programs. He also participated in the firm's quality
assurance program, counseling and development of its professional staff,

Armstrong holds a Bachelors of Science degree from St. John's University,
Collegeville, Minnesota. He is a member of the American Institute of Certified
Public Accountants and the Minnesota Society of Certified Public Accountants.
