“We are very pleased that eleven very talented local physicians have chosen to be more closely aligned with John Muir Health to serve patients in our community,” said Cal Knight, president and CEO of John Muir Health. “We are committed to a mixed-model physician network where independent physicians continue to be welcome and those who prefer being part of an integrated medical group have a local, community-based option.”

“We have a long history in the community and with John Muir Health and are excited to become part of the medical foundation affiliated with the health system,” said Dr. Voelkel. “We look forward to continuing to provide our patients with the excellent care they expect for many years to come.”

Arrhythmia Specialists, Inc. is based in Concord. Susan Eisenberg, M.D. and Carleton Nibley, M.D. are board certified in cardiac electrophysiology and have been providing cardiac ablation and device-based rhythm management to the community since 1995.

“John Muir Health has established itself as a regional leader in electrophysiology, ” said Dr. Eisenberg. “We're incredibly excited to strengthen our relationship within the health system and partner with them in the continued growth of the Cardiac Rhythm Center.”

Walter Savage. M.D., practices in Brentwood and has been serving East Contra Costa County since 1989. He is board certified in cardiology. “John Muir Health is a regional leader in cardiovascular services,” said Dr. Savage. “I look forward to continuing to serve patients in East Contra Costa County and providing them with access to the outstanding care and service provided at John Muir Health.”

John Muir Health offers a full spectrum of cardiovascular services that span both its Walnut Creek and Concord campuses, with physicians located throughout Contra Costa and Solano counties. The health system’s cardiovascular programs and expert medical staff have earned numerous awards, including the highest level of accreditation from the Society of Chest Pain Centers and recognition from the American Heart Association and designation as STEMI Receiving Centers for severe heart attack patients.
