Brett Tambakis

Director of Utilization Management

Brett Tambakis is the Director of Utilization Management for Sierra by the Sea and Sunrise Ranch and has over 7 years of helping patients in early recovery. Specializing in medical necessity criteria, Brett uses that experience to acquire authorizations from insurance providers which allow patients to gain effective lengths of stay so that they may focus on the treatment plan laid out by clinical team.

By focusing on proving medical necessity criteria, Brett has been able to put his experience to good use, helping hundreds of patients over the years. Brett’s attention to detail at Sierra by the Sea and Sunrise Ranch has garnered some recognition for his ability to overturn adverse decisions by insurance providers thus allowing patients to maximize their treatment. Brett may spend his days behind a computer, but it’s knowing he plays an integral role in patient’s recovery that gets him up in the morning.

When they’re not at Sierra by the Sea and Sunrise Ranch, Brett is an avid rock climber and loves spending time with his wife Shelby and his Australian Shepard, Maple.
