Professional History
Since 2015, Dr. Max Diamond has served as the Senior Medical Director at Regal Medical Group, one of the largest physician-led medical groups in the country, encompassing over 3,000 primary care physicians and 10,000 specialists. In this dynamic, multi-specialty organization, he and his team oversee hospital inpatient care, skilled nursing care, and utilization management, delivering high-quality medical services to more than one million senior, commercial, and Medi-Cal members. Regal Medical Group is renowned for its comprehensive wellness programs that promote healthy living within the community.
Before joining Regal Medical Group, Dr. Diamond held the position of Chief Medical Officer at North American Health Care. Under his leadership, the organization operated 35 healthcare facilities across four western states, achieving an extraordinary milestone where 100% of its facilities maintained a CMS 5-Star Rating for exceptional service and medical care. This achievement stands out, especially given that no other organization of similar size reached more than 25% of its facilities at that rating during the same period.
At the beginning of his career, Dr. Diamond played a pivotal role in founding the hospitalist medicine movement, which is now recognized as a standard board-certified medical specialty. He initiated three pilot programs for FHP, Kaiser Permanente, and Humana to validate the hospitalist concept. Following this, under the mentorship of Dr. Norman Jacobson in San Antonio, Texas, he established one of the first on-site inpatient hospital care programs in Florida for Humana Healthcare, personally recruiting, training, mentoring, and supervising a team of 65 full-time hospital physicians. Today, as the Senior Medical Director at Regal, Dr. Diamond supervises numerous hospitalist physicians, ensuring comprehensive care transitions from hospital to home.
Dr. Diamond is board-certified in Internal Medicine and fellowship-trained in Health Care Quality and Management, boasting over 20 years of both practical and managerial experience in healthcare. His dedication to hospice and end-of-life care has significantly transformed hospital culture, enhancing patient advocacy, reducing costs, and improving overall patient satisfaction. With extensive expertise in hospice/palliative care and medical-legal issues, he has served as a medical defense expert in over 40 cases.
Recognized as one of "America's Top Physicians" by the Consumer Research Council for more than a decade, Dr. Diamond has also received multiple honors, including the "Patient's Choice Award" and "The Compassionate Physician Award" from Vitals.com. He earned his undergraduate degree and medical degree from the University of California, Irvine, and completed his residency training at USC Santa Barbara (Cottage Hospital).
In addition to his clinical roles, Dr. Diamond served as a military contractor with the 554th Medical Group Emergency Physician at Vandenberg AFB, CA, and Nellis AFB, NV, where he held a high-level security clearance. He participated in numerous Operation Red Flag exercises, leading medical teams through high-intensity simulated combat scenarios in support of elite fighter pilots and crews from various nations. Furthermore, under a grant from President Ronald Reagan’s Strategic Defense Initiative (SDI), he conducted groundbreaking research on military lasers at the Beckman Laser Institute, resulting in publications in *Applied Optics* for his pioneering work with 408-nanometer Excimer Lasers.
An early overachiever, Dr. Diamond began programming in junior high school and mastered four different computer languages (Fortran, Fortran IV, Pascal, and C). As a high school freshman, he managed the computer sciences lab and appeared as a news anchor on local school district television, producing a five-part documentary on the development of South Coast Plaza titled "The Segerstrom Report." He graduated high school a year early while simultaneously completing a year of college-level math and science courses.
Dr. Diamond is also a nationally renowned trainer and lecturer for physicians and nurses, sharing his extensive knowledge and experience across the healthcare field.
