Leading the way

Meet the team that’s pioneering a new model of concierge medicine. After witnessing firsthand what didn’t work within the conventional system, our team set out to develop a smarter, more rewarding, and effective way to deliver healthcare. It’s a model that works better not only for physicians, but also for the patients who receive their care.

Matthew A. Jacobson

Chief Executive Officer / Founder

Matt Jacobson founded SignatureMD in 2006 with a deep commitment to placing the physician and patient back into the center of the healthcare equation. Starting from the ground up, he built SignatureMD into one of the largest personalized care membership programs in the nation with a rapidly growing network of over 200 affiliated physicians across 35 states. Matt plays an integral role in all facets of the business, while continually striving to maintain the family-business culture SignatureMD is known for.

Since the beginning, Matt and his team have been committed to delivering concierge-level service to the company’s concierge physicians, priding themselves on being available on their personal cell phones anytime, day or night, even as the network of physicians continues to grow. Matt’s personalized and straightforward approach, combined with the unique segmented concierge model he pioneered, has led to the successful long-term relationships he enjoys with affiliated physicians.

Prior to founding SignatureMD, Matt was senior vice president of medical management at Zenith Insurance Company (NYSE: ZNT), where he was responsible for turning around a $160M division with 200 employees that conducted business in 40 jurisdictions. During this time, Matt became passionate about improving the healthcare experience for patients and physicians. He found that an upfront investment in sending injured patients to talented, top-tier physicians meant that they often required fewer medical interventions, which resulted in a faster return to everyday life. The lessons from Matt’s time at Zenith laid the foundation for SignatureMD. In building SignatureMD, he set out to develop a care model in which patients could make an upfront investment in their healthcare in order to secure the time, attention, and consideration of a trusted primary care physician.

Matt is a serial entrepreneur, having established his first company at the age of 21, and rounded out his early career with operational management roles of increasing responsibility. In addition to his professional experience, Matt holds an MBA from the Anderson School of Management at UCLA and an AB from Cornell University. Over the years, he has taken on various leadership roles in the Young Presidents’ Organization, including chapter chair.
