Jennifer Lombardi 

Jennifer Lombardi
Director of Development

“What I really enjoy is the relationship-building inherent in fundraising. I like to find what uniquely and specifically speaks to each donor in order to help meet the financial goals of the school. To do this surrounded by devoted faculty and staff, caring parents and of course, the students, is  joyous and rewarding work.”

A graduate of Brandeis University with a law degree from Hofstra University, Jennifer began her career practicing law in Brooklyn. Jennifer and her husband eventually moved to California, where they raised their three sons, all of whom attended the Bentley School. Over 15 years Jennifer devoted significant volunteer efforts to non-profit fundraising and board development at Bentley, eventually transitioning into a career as a development professional for a number of non-profit schools in the East Bay. Outside of fundraising, she has spent several years as an appointed city council committee member in Berkeley, California. Jennifer and her husband live in Berkeley with their rescue dog, Leddy. When not raising money for great causes, Jennifer enjoys playing competitive mah-jongg.

Tamara Leider 

Tamara Leider
Operations Director

“I believe that all children are trying to tell us something, either through what they say or through their behavior, and that it’s up to us to slow down enough to listen, so that we can truly hear and see them.”

Tamara has her M.S. from the Columbia School of Journalism and an English degree from the University of California, Santa Barbara. She was a newspaper reporter before choosing to stay home with her three sons when they were young (all OHDS alumni, now in high school). She joined the front office team in 2014.

Blakemore, Jill

Jill Blakemore
Office Associate

“I am a firm believer in project-based learning. For concepts to be truly understood, not just memorized, they must be put into practice. That is when true understanding occurs and can be evaluated.”

She holds her bachelor of arts in history and religious studies from the University of California, Santa Barbara.
