BOULDER - Boulder Community Hospital's new Anderson Medical Center is filling up, as new medical practices are opening their doors in the recently completed 46,000-square-foot building.

The center, at 4743 Arapahoe Ave. in Boulder, is part of the hospital's $130 million expansion of its Foothills campus, located at 4747 Arapahoe Ave., between Foothills Parkway and 48th Street.

Two practices - Boulder Neurological and Spine Associates and Boulder Heart, a cardiologist practice - have opened in the new center in the past month.

Boulder Heart is a newly formed practice with 10 doctors, at Suite 201. It was formed after doctors from the Colorado Cardiovascular Center joined Rocky Mountain Cardiology, and it is affiliated with BCH.

Boulder Neurological and Spine Associates is next door, at Suite 202. According to Boulder County property records, the neurology office occupies a suite recently purchased for $2.23 million by Foothills Office LLC, which was formed by Alan Villavicencio, a doctor with the practice.

Alpine Surgical and Alpine Urology will open soon at the center, according to BCH's website.

Work continues on the 100,000-square-foot expansion of the hospital's main building, which will increase its bed count from 60 to 135 as the building becomes the hospital's main acute-care center.

The hospital also is buying property across 48th Street from the campus. It recently paid $1.2 million for the 4,780-square-foot office building at 4880 Riverbend Road.  The seller was Whitfield J. Collins, according to property records.

The acquisition is in line with the hospital's long-term plan to acquire the buildings in the Riverbend office park, which is to the east of the Foothills camps across 48th Street. The hospital already owns seven of the 12 small office buildings in the development around Riverbend Road.
