Robin Byrne, LCSW, Clinical Director, Cofounder

JP Grako, CFO, Cofounder
JP arrived in this field through personal and family experience, and a strong desire to lead others to achieve what he has, long-lasting sobriety. JP opened Alliance Sober Living in the fall of 2016, when he saw a gap in the availability of aftercare in the Scottsdale area. After opening his third house in 2018, he partnered with Gabe and Robin to create Purpose Healing Center. Purpose was created as a family business to help others achieve their ultimate goals and dreams, and to overcome the gripping effects of addiction. JP holds a bachelors in business from Grand Canyon University.
Gabriel Tomaeno, CEO, Cofounder
Gabriel’s own recovery led him to seek a career in this field. When he was battling addiction, he sought both Inpatient and Intensive Outpatient programs to guide him into recovery. With the support of the treatment programs, community support and his family he has been able to achieve sobriety. Eager to get involved in the recovery field, crediting his own treatment with saving his life, he enrolled in college with Addiction Treatment as his major. Gabriel’s role within the company is to ensure ethical and appropriate approaches to businesses growth including referrals, client care, operations, community outreach and much more. Being the CEO of Purpose Healing Center is much more than a title for Gabriel he takes pride in the company’s mission and holds it close to his heart “Help bring Treatment to as many people as possible”. Gabriel says the most joyous part about this field is talking to a new client and watching their hope rise when they feel the blessings of sobriety.
