Meet SteppingStone's Management Team


At each of our four ADHC Centers, SteppingStone's caring and compassionate staff are led by our diverse and highly skilled team of Program Directors. In addition to overseeing program activities and supervising staff, Program Directors are instrumental in helping our interdisciplinary care team develop each participant's individualized care plan, and ensuring his or her success in our program.


Executive Director—Daniel Gallagher

The Board of Directors of SteppingStone Adult Day Health is pleased to announce the appointment of Dan Gallagher as our new Executive Director effective November 19, 2018. 

Dan has had decades of experience providing service and support for several of the Bay Area's most disadvantaged and marginalized groups. A native of San Francisco, he spent twenty-five years with Catholic Charities, primarily helping troubled youth. His passionate advocacy of the most vulnerable will certainly expand to SteppingStone's frail elderly and disabled adults. John Tinloy, who served as Interim Executive Director, will support Dan during the transition as he gets familiar with SteppingStone.

John served as the first Program Director at Mabini, Presentation and Mission Creek Centers.
