Tria Orthopaedic Center, one of the metro area's largest specialty clinics for treating bone and joint problems, is hiring a new chief executive.

Dr. Edward Craig, an orthopedic surgeon in New York City, will lead the Bloomington-based center starting June 1.

Current CEO Dr. Marc Swiontkowski is stepping down to edit a medical journal while continuing to treat patients at Tria.

Orthopedic centers are investing in new facilities.

Last year, Tria announced plans for a new center in Maple Grove as part of a $48 million specialty center being built by parent company HealthPartners, which is based in Bloomington.

"We're constantly looking at where our development and growth opportunities are, but no plans at this point to bring forward," said Steve Housh, a HealthPartners vice president. "We're really focused right now on Maple Grove."

In December, Golden Valley-based Twin Cities Orthopedics announced plans for a new sports medicine clinic in Eden Prairie. The group also announced plans to move into larger clinic spaces in Maple Grove and Plymouth.

Rochester-based Mayo Clinic opened last fall a new sports medicine clinic in downtown Minneapolis, while a large physician group in the east metro called Summit Orthopedics opened a new center last year in Vadnais Heights.
