SANTA ROSA – Annadel Medical Group, part of St. Joseph Heritage Healthcare, announced another influx of six physicians, in addition to assuming the practice of recently retired Healdsburg pediatrician Dr. Damian Mardsen.

The new physicians increase to 70 the number of doctors who are part of Annadel Medical Group, which partners with  Santa Rosa Memorial and Petaluma Valley hospitals, according to St. Joseph Heath.

Dr. Marsden’s patients will continue to be seen at his longstanding office location at 445 March Ave., Suite A in Healdsburg, which will be staffed by Annadel pediatricians.

With the latest addition of physicians, Annadel has added neurology to its roster of specialties, while also expanding access to care from newly recruited physicians who practice obstetrics/gynecology, gastroenterology, family medicine and critical care.

“Annadel Medical Group is pleased to continue the expansion of services and specialties offered in Sonoma County,” said David Smith, president of Annadel. “Not only are we honored to offer quality pediatric care to the Healdsburg community with the same compassion that Dr. Marsden did for the past 33 years, but we are pleased to welcome this diverse group of primary care doctors and specialists to our local medical community.”
