OrthoConnecticut may not be a familiar name in the local medical arena, but it is the result of the merger of four very familiar practices.

Danbury Orthopedics, Coastal Orthopaedics, New Milford Orthopedics and Connecticut Pain Care have merged into one business to create a “musculoskeletal center of excellence,” said OrthoConnecticut officials.

The practice boasts 31 board-certified orthopedic and pain-management specialists in nine offices, including a new 43,000-square-foot central hub in Berkshire Corporate Park in Danbury. Other locations are in Westport, Norwalk, Darien, New Canaan, Ridgefield, New Milford and Sharon. A Southbury location is scheduled to open soon. It serves patients from Greenwich north to the Massachusetts border.

Dr. Michael Brand, co-president of OrthoConnecticut, said the practice has retained the local specialists that patients are familiar with and the individual practices will use the former name as sub-branding — such as OrthoConnecticut/Coastal Orthopaedics — until people become more familiar with the new name.

“We needed a name that unites the practice,” Brand said. “I think people will get comfortable with the name. We don’t want anyone to think we’re a new national company.”

Danbury Orthopedics was founded in 1954 and Coastal Orthopaedics in 1963. Dr. David Kloth founded Connecticut Pain Care in 1995.

In addition to orthopedic, spinal and sports medicine care, OrthoConnecticut has expanded in the areas of pain management, hand therapy and physical therapy. OrthoCare Express, a walk-in urgent-care service for orthopedic injuries such as fractures and sports injuries, is available at the practice’s offices in Danbury, Darien, Norwalk and Westport.

“This new alliance allows us to provide the most advanced care in a more individualized and efficient fashion, offering a broad array of services and locations,” Dr. Michael Lynch, co-president of OrthoConnecticut, said. “Our name has changed, but our patients can expect the same type of high-quality individualized service that they have received for years.”

Coastal Orthopaedics, Danbury Orthopedics and New Milford Orthopedics quietly merged in 2015 under the name Western Connecticut Orthopedic Specialists. This year, the practice brought in Connecticut Pain Care and rebranded as OrthoConnecticut. Connecticut Pain Care will move from its location on Mill Plain Road in Danbury to the new hub at 2 Riverview Drive in Berkshire Corporate Park.

In 2014, Coastal Orthopaedics and its hand therapy practice moved from a

medical building at 40 Cross St. in Norwalk to iPark, the former Perkin-Elmer site that straddles the Norwalk/Wilton border.

Next month, OrthoConnecticut will move its Westport location from the Willows Medical Center to a state-of-the-art, 5,000-square-foot facility at 323 Riverside Ave. Coastal Orthopaedics has been in Westport since 1994.

The new Danbury facility, built by Maplewood Healthcare, opened this spring and consolidated former locations in Danbury, Brookfield and Newtown. Office positions have shifted to the new facility from its White Street surgical center, which remains open as an expanded surgical center.

Danbury Orthopedics added the surgical center in 2014 as part of a $5 million upgrade of the White Street location.

The central billing office will move to Mill Plain Road, the current site of Connecticut Pain Care.

OrthoConnecticut’s pain management services will be expanded to four specialists to treat and control chronic pain. The pain management team uses advanced interventional pain therapies and regenerative medicine techniques to repair injuries and restore function. Connecticut Pain Care will move to the first floor of the new Danbury facility next month.

The building at 2 Riverview Drive is home to Specialty Imaging Associates, the only tenant not affiliated with OrthoConnecticut.

Brand said the timing was right for the merger and expansion of the orthopedic practice with the growing popularity of youth sports and baby boomers remaining active into their 70 and 80s.

“We’re seeing injuries in 75-year-old athletes. They want to stay active,” Brand said. “With the aging of the baby boomers, we are preparing for the future.”
