Zac Spowart, LAADC, MBA, Chairman

On his way to becoming Chief Executive Officer/Co-founder of Silver Lining, Zac sought to strengthen his educational background and did so by obtaining degrees in different areas and specialties. His fascination with the human body along with physical, emotional, and behavioral development was founded in his undergraduate Kinesiology degree with a pre-medical course focus. From there, Zac proceeded to enhance his education by attending the highly acclaimed and internationally recognized Hazelden-Betty Ford master’s program which focused on addiction counseling and co-occurring disorder treatments. His experience at Hazelden not only solidified his passion for the field, but it provided elite and industry-leading fundamentals for addiction recovery and the supporting research. His clinical practicum allowed him the opportunity for on-site rotations that ranged from treating males and females of all ages, and various levels of care. This included adult and adolescent residential and detoxification, day treatment, intensive outpatient programming, and standard outpatient. These diverse levels of care provided well-rounded exposure and clinical aptitude for a wide range of behavioral, mood, and personality disorders that often accompany addictions and the subsequent best evidence-based practices for their treatment. Zac has since applied these foundational components to treat hundreds of clients and families who suffer from the disease of addiction. As he remained in the field, his passion to help others grew and he eventually sought his MBA from Pepperdine University. It is his core belief that this blend of clinical experience and business insight will lead to the greatest levels of success for all staff and clients who participate in Silver Lining programming. Aside from his professional and educational experience, Zac also brings his own personal experience in recovery to Silver Lining. Zac battled addiction at a young age, and consequently received treatment and became sober at the age of 21. His personal and professional ties to addiction have helped steer him towards seeking to assist others in any manner possible who struggle with the disease of addiction and other disorders. Zac has worked in various roles from Counselor/Case Manager, Program Developer, Group Facilitator, Director of Quality/Compliance, and Director of Operations at multiple mental health rehabilitation facilities across the United States. He is excited about his role at Silver Lining and looks forward to using his skills and experience to help others struggling with all forms of addictions and any disorder that causes a client discomfort or pain. Engaging with the clients he encounters on a regular basis is what he loves most about his job. He enjoys learning about each client and helping bring out their best personality traits and qualities while on their journey to sobriety. In addition to establishing and growing relationships with individuals seeking treatment, he is also passionate about the development of other counselors and staff. He strives to create a professional environment that people are drawn towards and enjoy. After becoming sober, Zac obtained his helicopter pilot license, became scuba certified, and traveled to all the 50 states and Europe. In his free time, Zac participates in triathlons and marathons and trains for them regularly. He attributes these opportunities to his gift of sobriety and seeks to encourage others to have all they can dream of and more as they too recover.



Barmak Hefazi, Founder

Barmak attended CSUF Miyahlo School of Business and studied accounting and started a career working in tax accounting and the financial sector. After working in that industry for 10 years, he decided he needed a change. Barmak went back to school to study to become a therapist. He began working in rehabilitation facilities (from small facilities to large centers) and enjoyed the work.

Barmak soon discovered he had a knack for filling in those missing pieces and establishing a seamless administrative process for clients. At Silver Lining, Barmak wants clients to know their health and recovery is the focal point of the treatment they will receive. He has created an administrative system that will allow clinicians to focus solely on client care, rather than spending countless hours on the administrative side like filling forms and other office tasks. He has invested in up-to-date, innovative technology that will allow clinicians to do what they do best: providing high-quality care for their clients. In his free time, Barmak spends time with his wife and 2-year-old son as a family man. Also, he likes to keep active by playing soccer regularly and maintaining his skills as an amateur MMA fighter.
