Steve Hendrickson, treasurer

Steve first visited Tanzania in 2009 with the Museum of Science, and was delighted to return with a group of family and friends in 2014.

Seeing the animals in their natural habitats and meeting some of the Maasai people made Deborah’s 2015 visit to Tanzania her “best vacation ever!”  She remembers learning about 17 students sharing one book and funds for lunches running out at the end of the school year.  After reading about FoTZC’s important projects, Deborah joined the board in 2016 to help improve conditions for these radiant people.  Following marketing positions at Levi Strauss, Wells Fargo and Charles Schwab, Deborah was an independent management consultant for 23 years.  She has served on ten nonprofit boards, including officer positions for Hunters Point Family, Ohio State Critical Difference for Women Foundation and San Francisco Maritime National Park Association.


Katherine is the deputy director of Behavioral Health Integration and Accountable Care at the Massachusetts Health Policy Commission where she oversees efforts to integrate capacity to address mild mental illness and substance use disorders into primary and acute care settings, and primary care capacities in to community mental health centers (via investment and certification initiatives).

Prior to that, Katherine worked on public health law reform, firearms control, and global preparation for pre-exposure prophylaxis to prevent the transmission of HIV (PrEP) at the O’Neill Institute for National & Global Health Law at Georgetown University.

Bob Treitman spent a year in Tanzania, working as a volunteer at The School of St. Jude, a school for very poor, but bright and motivated children from the Arusha area. When he and his family returned to the US in 2006, he brought his knowledge and experience to FoTZC, where he serves as the chair of its Programs and Policies committee. He’s twice returned to Tanzania (in 2008 and 2014) with other board members to listen to community representatives, evaluate existing FoTZC-supported projects, and consider new proposals. Bob, who spent two years of his childhood in Nigeria, now lives in the Boston area with his wife (who volunteered as a nurse with Flying Medical Services in Arusha). A graduate of Brown University and Harvard School of Public Health, he recently retired from Adobe Systems but not-so-secretly longs for an excuse to return to Tanzania.
