Who We Are
Health by Design is a privately held organization committed to transforming how healthcare is delivered. We work alongside employers, individuals, and families to deliver healthcare they way it should work.
Today, we partner with more than 200 employers and support thousands of individuals and families across the country – and our commitment continues to grow:
Led by Love
Health by Design began with a simple belief: healthcare should feel personal. After returning from military service, founder David Player envisioned a different kind of care — one guided by faith, driven by purpose, and rooted in passion for people.
What started in San Antonio with a focus on obesity and diabetes care became the foundation for Health by Design in 1985. Over the next four decades, that vision grew into a network of care that has served nearly one million patients. As the vision evolved, David Player entrusted Clint Phillips to carry the mission forward for the next generation.
Today, we continue to build on that foundation by redefining what is possible in healthcare through executive, onsite, and virtual care. Led by love, we are setting a new standard for how care is delivered and experienced.

Our Mission
To be the leading provider of lasting wellness through faith-driven care.
Our Vision
To glorify God by transforming healthcare across the nation.
Our Values
Great care begins with great people.
