Our Story & Our Team
Steve and Diahann understand that they are only as good as their team and that there is no substitute for experience. In turn, they have worked hard to acquire the most talented, seasoned and passionate treatment professionals in the field. They are immensely proud of the La Ventana multi-disciplinary treatment team which consists of some of the most dedicated, compassionate and highly trained treatment professionals, perfectly poised to treat those struggling with mental health, chemical dependency and co-occurring issues. The client-to-staff ratio is low so as to be able to offer depth of personal connection, individualized support, and accountability at every step. The staff are a close knit team in constant communication, hypervigilant about each client’s unique needs upon admission, throughout their stay, and after they launch back into life. The staff understand the clinical interventions and overall care required for a successful treatment experience as well as the aftercare planning necessary to be able to sustain long-term recovery. Once a client admits, they genuinely become part of the La Ventana family and staff will do everything in their power to not let their family member fall.
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.
Diahann Klein, MA, LMFT
Chief Executive Officer
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. At the helm of the La Ventana team, she is the face of the company externally, and internally inspires and empowers staff at all locations, while coordinating effective and client-focused care.
Diahann says, “Witnessing and facilitating the healing process is what drives, inspires, and sustains (her) in every aspect of (her) day-to-day work.”
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.
Diahann also serves the greater addiction and mental health communities at large in various advocacy, advisory, and Board positions. She is an active member of International Association of Eating Disorder Professionals (iaedp), and is immediate Past President of the Los Angeles Chapter. She held a board position on the Women’s Association of Addiction Treatment (WAAT), San Fernando Valley Chapter, and is also a member of the California Association of Marriage & Family Therapists (CAMFT) and the Academy of Eating Disorders (AED). In her various Board positions, she has developed addiction and mental health educational workshops, intervention and awareness campaigns, and high-level professional training for practitioners.
“There is hope. There is help. This is the message I want clients to hear. Our team has a profound understanding of the recovery experience which allows them to deeply hold space between themselves and the client. It is in this very space where clients gain trust and change manifests.”–Diahann Klein, CEO
Director of Clinical Outreach
Other than the people I love and my precious pups (Chips and Oz), there is nothing more important to me than recovery, my recovery and the recovery of those in need. As a teenager, before I had even reached the legal drinking age I became a resident at the newly opened Betty Ford treatment program in Rancho Mirage. This experience changed my life forever. My newly found life in sobriety brought a smile to my face and gave me a twinkle in my eye. It gave me love in my heart and I found myself repeatedly discovering that all things were possible. However, while my life was full and I was in the throes of a successful career, it was in 2009 when I realized something was missing. I wanted and needed a more meaningful career path, one that filled my heart and soul; however, I had no idea what that looked like. It seemed that it was time to do a little soul searching. After months of prayer and meditation, I attended a Memorial Day party at a friend’s house and spent the better part of the afternoon talking to her 20-year-old daughter about treatment and sobriety. As I walked away from that discussion, I had an epiphany. The thing I am most passionate about is helping people who are struggling with addiction to find and get the help they need. Again, I didn’t know how that translated into a career; I just knew there was something there. A couple of weeks later, I came across an admissions position at a young adult treatment center. That was 5 years ago. I have been in the field of recovery ever since. My heart has never been so full. Nothing is more fulfilling to me than connecting families and those fraught with addiction with the resources they need. My position at La Ventana not only allows me to introduce our program to families and those seeking help for themselves, but it also gives me the ability to present our services to countless professionals, facilities and institutions who have direct contact with so many who are in need. La Ventana has given me the platform to reach more people than I ever imagined.
Prior to joining La Ventana, I was employed at Sober College, a young adult rehabilitation program. During this time, I had the opportunity to collaborate with La Ventana on many occasions. Since we shared many clients I saw firsthand the treatment and level of care La Ventana’s team provided our clients. Through these experiences, La Ventana earned my deepest respect and trust. Over the course of the last 5 years, I fell in love with the entire LV leadership and clinical teams and they became my extended family. When Sober College opted to close their doors, my LV extended family reached out to let me know that I had a home at LV if I wanted it. How could I say no? Not only do I work with people I adore, but I am also blessed with doing that which brings me tremendous joy!
With over 20 years of experience in sales and marketing, Buffy is excited to be a part of the La Ventana family! Buffy’s career has always been about connecting with people – getting to the true human layer that connects us all. She began her career in outplacement consulting, working with folks who were transitioning between careers and needed a lot of extra TLC and encouragement. She then landed in pharmaceutical sales where she got to bring her love of helping others into the medical arena. By way of educating physicians, nurses and their medical staff about the pharmaceutical regimens she had the honor of representing, she was able to make an impact in patients’ lives.
After almost a decade, she then continued her career in medical sales on a much smaller scale, working on various projects in different arenas: audiology, Durable Medical Equipment, and mental health programs. Once again, she was able to use her real love of people and the differences we all have to connect and make a difference for patients.
Most recently, Buffy went through her own personal journey and change and discovered the magic of bikram yoga and meditation. She saw how powerful it could be to be present, turn inward, and face her own issues and manage them head-on instead of turning away from them. This awareness combined with her genuine love for people and connection is what makes Buffy an integral part of our team.

My deep passion for fitness led me to begin practicing yoga over 10 years ago. I quickly learn that there are significantly more important gains from practicing yoga than just the physical ones. My classes are carefully planned as observing students’ bodies and adjusting their poses with the help of props such as pillows, straps, and blocks as needed is part of my teaching routine. Yoga gives people the opportunity to be alive, loved, and free. I am grateful to share something that I am passionate about with other people.
