Jayme Ambrose DNP RN CCM – Chief Executive Officer

Jayme Ambrose, DNP, RN, CCM, is the visionary Founder and Chief Executive Officer of Adobe Population Health, an Arizona-based company offering an innovative, first-of-its-kind solution to the issue of health equity. Founded in 2018, Adobe employs a technology-driven model for interventional care management and takes a holistic approach to population health by closing care gaps, reducing costs, and caring for the whole person.

Armed with a Master of Science-Nursing from Arizona State University, Jayme was accepted into the Doctoral program for Nursing Science & Leadership at Case Western University. It was there that she developed an integrated case management model as part of her doctoral studies, with the objective of addressing the social determinants of health that often contribute to poor health outcomes for at-risk populations. After completing her doctorate in 2013, Beech Medical Group agreed to support piloting her model if Jayme agreed to accept a position as VP of Clinical Services. In 2016, she signed her first insurance company contract and initiated a holistic approach to case management for Medicare members.

Her model integrates data analysis and risk assessment with a human touch to deliver proactive and preventative care that improves health outcomes, decreases hospital and ER visits, and reduces overall healthcare costs. In 2018, Beech Medical Group sold the company, but not before giving Jayme the opportunity to purchase her division. On that day, Adobe was born with one mission: To positively impact the lives we touch.

As part of an innovative technology platform, Adobe utilizes proprietary risk stratification tools to identify the issues of those at greatest risk, including food insecurities, financial hardships, transportation issues and even loneliness. And then through a proprietary and groundbreaking application called MASLOW™, members are invited to answer questions related to social determinants of health and are then are connected to for-profit, non-profit, and governmental resources based on geolocation. To ensure impact, a qualified team member, through a hybrid care model, reaches out to offer assistance, closing the care loop. It is this human touch that sets Adobe apart from other case management organizations. Today, Adobe employs over 300 employees in clinical healthcare services, data analysis, software development, and administrative roles, serving more than 400,000 across the lifespan and in eight states.

Jayme is a member of the Arizona Nursing Association and has served on several boards, including The Arizona Homecare Association, The American Association of Occupational Health Nurses, and the Case Management Society of America where she is currently a member of the Rural Special Interest Group Advisory Panel. Jayme also serves on the Women’s Executive Leadership Team of the American Heart Association.
