About Us

The PDA Capital Area Chapter has its origins dating back to the fall of 1992. It all started with a phone to PDA President Edmund Fry from Rande Leibowitz, who had just moved to Maryland from New England, where he was active in the New England Chapter. When he was informed that no local PDA chapter existed, he asked the simple question, "why not?" Soon Rande found himself with a list of local PDA members and a mission: form the chapter.

Rande got together with a core group of dedicated volunteers and started work on the chapter's first activity: a questionnaire to gauge local interest. Soon we organized our first meeting. In the spring of 1994, Rande Leibowitz was elected first Chapter President, along with Bill Stoedter, Kelly Langan and Sylvia Issacson as President-Elect, Secretary and Treasurer, respectively.

We have been holding three to four meetings a year, consisting of both conventional dinner meetings and site tours of local facilities. We have heard excellent presentations by various speakers including our very first meeting in 1993, where Mike Beatrice (then at FDA) spoke about multi-use facilities and changes in FDA.

There are many people and companies to thank for the success of the Capital Area Chapter. Without them, we wouldn't be able to serve the Washington, D.C. Metro area PDA members with fine local programs and events. Thanks to all and keep up your support!
