Lisa M. Marandas

Deputy Director

Lisa Marandas brings extensive training and experience in several areas critical to the mission of Harbor of Hope. She has worked in business development for two major hospital systems, both in an administrative capacity and more recently on the patient care side. While with Legacy Health System, Lisa provided direct care for clients in mental health crisis, focusing on treatment and crisis management.

Lisa also worked in community-based, acute, crisis and residential long-term recovery programs while with Telecare programs based in Alameda, Calif. Her focus was in areas of milieu management, crisis intervention and treatment planning.

Outside of the realm of healthcare, Lisa led the development and execution of marketing, training and public relation strategies for start-up and larger corporate organizations.

Lisa believes that relationships drive success. She has demonstrated her ability to sell an idea, but feels her greatest wins occur when she can build a bridge with someone needing a hand.  She is driven by her passion for helping others. and feels her work for OHOH is the culmination of all efforts along the way.
