The American Podiatric Medical Association, a national organization of nearly 9,000 doctors, will move to its new headquarters at 9312 Old Georgetown Rd. in Bethesda later this week.

"We were jammed here and really had a Rube Goldberg sort of exercise going with the shoehorning of cars into the few existing parking spaces," said Dean M. Wakefield, director of public affairs for the APMA. "We also needed the additional room for our expanded computer-based services."

The APMA's headquarters has been at 20 Chevy Chase Circle, a building that it owned and occupied since 1968. That building was sold in what Wakefield describes as "roughly a wash" with the purchase of the new building.

More than a year ago, overcrowding at its Chevy Chase Circle office prompted the group to look for a new location. Its staff had grown from 15 to 41 since moving into the building.

The new site was purchased in January 1986 from The American Red Cross for just under $2 million. The building, which previously housed laboratories, is 24,000 square feet -- more than double that of the previous location. The 2.5 acres included with the building also allows for future expansion.

MR&A Architects oversaw the $1.5 million renovation of the building. Features include a neoclassical facade, a two-story glass entrance pavillion and a Pladium-style entrance. The building also has a library, a printing plant, an audio-visual center and a dining room.

"With this move, we're closer to NIH {National Institutes of Health} and the growing concentration of other medical associations nearby," said Wakefield.

The new site will be more technologically sophisticated than the previous location. It will house the APMA's expanded computerized-billing and desktop publishing operations.
