Personal Notes:

Chief Medical Officer, Robert W. Brenner, MD, MMM, oversees and implements strategic growth and continuous improvement of care for individuals and populations, while ensuring the appropriate cost of care at Summit Medical Group ― the largest for-profit, physician-owned multispecialty practice that manages approximately 170,000 patients in New Jersey.

An innovator in health care, Dr. Brenner has developed a unique hospitalist program that has dramatically reduced the average length of hospital stay and hospital readmission rate for Summit Medical Group patients. In addition, he has developed extensivist programs in geriatrics and rehabilitation medicine, which deliver continuous care to many Summit Medical Group patients. He also has developed a Transitions-in-Care Working Group that addresses the immediate and transitional needs of high-risk and other appropriate patients. Most recently, Dr. Brenner created a Practice Transformation Department that ensures all Summit Medical Group primary care providers collaborate and practice as a team to ensure the best possible outcomes for patients.

To enhance care for patients with certain disease states and ensure growth of the Group’s clinical programs, Dr. Brenner has developed a nationally recognized Breast Care Center, Behavioral Health and Cognitive Therapy Center, Evening Primary Care practice, Preventive Medicine practice, Diabetes Live Well Program, Executive Health service, Occupational Health service, and Medical Research division. To his credit, Dr. Brenner developed the first formal group practice affiliation with Memorial Sloan-Kettering Cancer Center. He manages more than 340 practitioners.

A spokesperson on the topic of health care reform and what it means for patients and physicians, Dr. Brenner has been an invited guest on Fox Business News and In Full View. He has delivered local, regional, and national presentations on value in health care, patient satisfaction, preventive medicine, effective health care systems, multispecialty group practices, practice management, and the meaningful use of health information technologies.

Before joining Summit Medical Group as Medical Director in 2006, Dr. Brenner was a lead hospital administrator, Executive Team member, and Chairman of Family Medicine at Atlantic Health/Mountainside Hospital. As a member of the Executive Team, Dr. Brenner implemented strategies to build new programs and contain costs that helped bring the hospital from operating at a loss to breaking even. In addition, the Mountainside Hospital Family Practice Residency Program became one of the most competitive residency programs in New Jersey under his direction. He has been Director of the Outpatient Ambulatory Center and Associate Residency Director at Somerset Medical Center in Somerset, New Jersey, and he has practiced privately in Westfield, New Jersey.

A US Air Force Health Professions Scholar, Dr. Brenner earned a US Air Force Commendation and Meritorious Service Medal. During his residency training, he earned medical teaching awards. He is the recipient of the Joseph E. Enright Kingfisher Award for his outstanding contribution and dedication to the health education mission of the Joseph E. Enright Foundation. In addition, he has earned the Dorland Health National People Award. Dr. Brenner has been featured in New Jersey Family "New Jersey's Favorite Kids' Docs" listings.

Dr. Brenner is an invited member of the New Jersey State Department of Health (DOH) Quality Health Care Advisory Committee. He is a fellow of the American Academy of Family Physicians and a member of the Group Practice Information Network, American College of Medical Quality, Medical Society of New Jersey, American College of Physician Executives, New Jersey Health Care Quality Institute Provider Council, American Medical Group Association (AMGA) Chief Medical Officers Leadership Council, and AMGA Foundation Board of Directors. Dr. Brenner is Past President of the New Jersey Association of Family Practice Residency Directors and Past Vice President of the Somerset Independent Physician Association. He was recently designated Innovation Exchange Leader for the Brookings Institution Engelberg Center for Health Care Reform Accountable Care Organization (ACO) Learning Network. Dr. Brenner has participated in the new York University Stern School of Business Strategic Leadership Executive Program. 

Dr. Brenner notes, "Medicine has fascinated me since I was very young. I have found many rewards in practicing medicine and helping people manage or get better from an illness." Dr. Brenner's philosophy of care includes wellness as a partnership between the caregiver and patient. He believes that patients benefit from information about preventive care and health maintenance. He adds, "Educating patients helps them make proactive decisions to protect their health."

When he is not with his patients or overseeing improvements at Summit Medical Group, Dr. Brenner enjoys cycling, skiing, wilderness backpacking, and vacationing with his family in the Berkshire Mountains of Massachusetts.
