National Leadership Team

Steve Taylor LobbySTEVEN TAYLOR

President & Chief Executive Officer

A mission-first leader in the voluntary health space, Steve has over three decades of experience devoted to making life better for patients with life-altering diseases.

Since joining the Arthritis Foundation in 2021, Steve has established the organization’s multi-year strategic mission plan, which outlines the Foundation’s clear pathways to finding a cure and improving quality of life for the nearly 60 million Americans diagnosed with arthritis.

Steve is passionate about aligning the Arthritis Foundation’s advocacy agenda and science strategy with the organization’s priorities, which are shaped by patient voices. Steve’s leadership is guided by the Foundation’s strong community of patients and volunteers — who are critical in driving the organization’s progress in boldly attacking arthritis and its effects.

Prior to being named president and CEO in 2022, Steve served as the Arthritis Foundation’s executive vice president for mission and strategic initiatives for the prior year. Previously, he served as president and CEO of the Sjögren’s Foundation for 18 years, from 2003 to 2021. While there, Steve worked to make Sjögren’s a household name, increasing awareness among the general public and health care professionals. He also notably led the development of the first-ever Clinical Practices Guidelines for Sjögren’s, a resource to help physicians treat, manage and monitor their patients.

Since childhood, Steve has been devoted to worthy causes, including the Muscular Dystrophy Association’s telethon and the American Heart Association’s Jump Rope Heart program. He has also served in staff leadership positions at the American Heart Association and the American Cancer Society and, in 2012 and again in 2019, served as volunteer chair of the National Health Council board of directors.

Steve holds a bachelor’s degree in political science from Boston University and an executive MBA from Auburn University. He is the proud father of three sons.

“It is my greatest honor and joy to work alongside our volunteers and patients, who serve as my biggest inspiration,” says Steve. “That’s what is so powerful about being part of a mission like ours. Their stories are what fuel us as we champion the fight against arthritis together.”
