Steve Zamarripa, MBA

Chairman of the Board
Steve’s Story: Born and raised in Southern California, Steve earned his BA from USC and his MBA from Columbia University. Steve had launched, grown and sold several highly successful businesses over the years and began to realize what he thought was the American dream – independence and abundance amidst an early retirement. Once that dream materialized Steve became increasingly aware of a profound emptiness and felt something essential in his life was missing. He craved a life of more substance, where he could give back and make a difference, and so began his journey inward in search of meaning and connection.

During his self-reflection, Steve began to gain insight into the profound impact his family of origin experiences had had on his development and, in turn, his ability to have meaningful connections with others. The lives of his father, grandfather and uncles were fraught with alcoholism and addiction and his mother had suffered an eating disorder which contributed to her early death. With his primary caregivers living in the grips of addiction and an eating disorder, Steve was left to fend for himself in a household full of fear and dysfunction. As an adult, despite his best efforts to change the intergenerational patterns of dysfunction that he experienced, Steve saw his own familial relationships continue to suffer. In 2007 Steve had a spiritual awakening when he realized he had been living only as a survivor. This realization in conjunction with inspiration from his personal experiences manifested a desire to create a place to help, a peaceful place for people to heal. La Ventana Treatment Programs became that place: a home for professionals deeply invested in the recovery process, and a place for those suffering from substance abuse and mental health issues to find help and long-term recovery. La Ventana is held up by a stellar staff that carries the same passion for recovery and service that Steve does. With the birth of La Ventana Treatment Programs, Steve has found a way to give back to the world, fulfilling his passion to help others live long and prosperous lives.

Chief Executive Officer (CEO)

Diahann’s Story: Diahann grew up in New York, the daughter of a union president and high school math and chemistry teachers, within a household that respected academic achievement and social and political activism. Working hard to live up to what she interpreted as the highest of her familial and societal standards, she catapulted forward daily in a relentless pursuit of perfectionism and accomplishment. Diahann graduated cum laude with a B.A. in Political Science and Music from Middlebury College in Vermont, and she studied at the University of Wisconsin at Madison and the London School of Economics and Political Science. She went on to pursue careers in politics, real estate, and entertainment in NYC and Los Angeles. She found financial success and her life on paper appeared to be one of abundance. Simultaneously, she was desperately attempting to navigate a progressively debilitating eating disorder with secrecy and shame. She was using anything she could consume in an attempt to fill a void for which there would never be enough. Eventually she ended up in treatment, catapulted into a journey inward. Her ensuing life in recovery led her to get an MA in Psychology from Antioch University and to become a licensed Marriage and Family Therapist. Thereafter, she became immersed in the substance abuse and mental health treatment worlds.

Diahann offers a unique combination of extensive clinical and executive experience along with a personal connection to recovery in all aspects of her leadership.

Her plans for La Ventana’s growth and expansion have been in alignment with her profound understanding of the complexities of addiction and mental health, supporting her commitment to comprehensive care and further advancement of ethical practices and professional standards.

She is an active member of International Association of Eating Disorder Professionals (iaedp), and is immediate Past President of the Los Angeles Chapter.
