Justin Murphy, currently the city's public works director, has been promoted to deputy city manager.
Sean Reinhart has been named permanent library services director, following a stint in the interim position.
Theresa DellaSanta has been named human resources manager. She currently works as Atherton's deputy city manager and city clerk, and is expected to begin her new position on May 20.
Both Murphy and Reinhart began work at their new positions on April 29.
"In a competitive labor market, our ability to retain and attract talented professionals is a credit to the organizational culture created by the current and past city councils," Jerome-Robinson said in a statement. "Menlo Park is a great place to work. Our city is financially stable, we invest in our employees through training and career growth opportunities and we have exciting projects in every department."
According to Jerome-Robinson, the only remaining vacancy at the management level is the assistant community development director for building position.
Murphy lives in Menlo Park and started working with the city as an associate planner in 1996. He moved up through the ranks and was named public works director in 2016. He will continue to oversee the Public Works Department and manage more city matters.
He has a master's degree in public administration from the Kennedy School of Government at Harvard University and a bachelor's degree from Stanford University.
Jerome-Robinson said that Murphy's "intellectual rigor and deep knowledge of the Menlo Park community are true assets to the city."
Reinhart took on the position of interim library services director in October 2018, after the former director, Susan Holmer, retired. He previously helped in the process to build a new library in the city of Hayward as library director in that city from 2009 to 2018.
He has also worked in the Redwood City and Santa Clara University libraries, and holds a master's degree in library and information science from San Jose State University.
Jerome-Robinson said Reinhart "brings with him a wealth of management experience that will serve our community well."
DellaSanta will take on the position of human resources manager, which has been vacant since August 2018, when the prior manager, Lenka Diaz, was promoted to administrative services director.
DellaSanta has worked in Atherton since 2009 in a series of positions, including human resources manager, city clerk and interim city manager, prior to her work as deputy city manager. Before coming to Atherton, she was deputy board secretary for the San Mateo County Harbor District.
She has a master's degree in public administration from Golden Gate University.
Jerome-Robinson said that DellaSanta's "broad experience in local government management provides her with the background necessary to continue the good work of our human resources team."
