WASHINGTON — With deepest regret and in great sorrow, America’s Physician Groups announces that Jennifer L. Jackman, APG’s chief operating officer, died tragically in a scuba diving accident while on vacation in the South Pacific earlier this week. She was 67.
Jennifer joined APG in 2019 after a long and distinguished career as a health care executive in California. She previously served as the chief executive officer of Edinger Medical Group in Fountain Valley, CA, as well as of Bright Health Physicians of Presbyterian Intercommunity Hospital (PIH) in Whittier, CA. Other key positions that she held included chief operating officer of MemorialCare Medical Foundation and senior vice president of medical group operations at then-named Optum/Monarch Healthcare in Irvine, CA. While in many of these positions, she also served on APG’s Board of Directors.
Jennifer joined APG full-time to lead business development and was promoted to chief operating officer in 2023. “She was my right-hand person in running APG, with her superb business skills and nearly irreplaceable knowledge of the California health care marketplace,” said Susan Dentzer, APG’s President and Chief Executive Officer. “She leaves an inestimable void for all of us, on both professional and personal levels. We are deeply saddened and send our most heartfelt condolences to her family and our other colleagues in health care, who have lost a trusted adviser, wise mentor, and a dear friend.”
Jennifer leaves behind multiple family members, including her daughter, Devon Prophet, and son-in-law Mason Prophet; her granddaughter, Emmerson Prophet; her mother, Carole Harter; and her sister, Jessica Jackman Uy, brother-in-law Allan Uy, and niece Juliette Uy.
An avid amateur scuba diver, Jennifer had previously taken multiple dives worldwide. Her family, friends, and colleagues will long remember her undying commitment to the success of the Los Angeles Dodgers and her longstanding support for the Center Theatre Group, a Los Angeles-based not-for-profit, along with her devotion to APG.
A memorial service and contributions to a gift in Jennifer’s honor and memory will be planned for a later date.
