Lisa K Montes

Chief Executive Officer

Learn More

Born in Chicago and raised in Long Beach, California, Lisa Montes joined the Del Amo staff in May 1997. She has over 30 years of administrative experience in the healthcare arena, primarily focused in mental health. Montes earned a BSW from Whittier College and an MSW from San Diego State University. Involved in a number of volunteer endeavors as a pre-teen, she found herself drawn to working with individuals struggling with medical and emotional challenges. This led her to focus on social work as a career path. The administrative or operations role was a natural fit.

Montes is passionate about her work because, “as a hospital, a team, we are more powerful and have greater opportunity to affect people’s lives and make an impact on our community,” she says. She adds that she’s grateful to work alongside such a dedicated, compassionate staff and medical staff.

When not working, she is a dedicated fan of pro baseball and basketball and she loves the outdoors. Montes is also passionate about music, theatre and the arts. The board president for a children’s charity for over 15 years, she also has wonderful adult children, a lovely group of friends and a great support system in her extended family, friends and coworkers.

Medical Director

A member of the Del Amo staff since the beginning of his career in 1981, Dr. Peter Hirsch is certified by the American Board of Psychiatry and Neurology. Born and raised in Los Angeles, he completed medical school and his psychiatric residency at UCLA.

Dr. Hirsch says that working at the hospital has allowed him to help patients and their families at times of crisis when an opportunity for recovery and change is most acute. “Not only is there great satisfaction in helping people during these times, but doing so as part of the hospital’s interdisciplinary team allows me to feel that the work we are doing is inclusive of all aspects of a patient’s life,” he adds.

His dedication to this work and to Del Amo is clearly matched by the dedication of the hospital’s staff, which creates a professional and caring environment.
