Marcus Abernathy

Sangha's Founder and Executive Director Marcus Abernathy has a Master's Degree in Psychology, is in recovery from heroin addiction, and has lived in and managed sober living environments since entering recovery. His education, experience, and passion for helping others led him to being founder of Tulsa's newest concept in Sober Living - Sangha.  

"I have seen what works and what doesn't, and I wanted to create an environment that gives our residents the best chance of re-integrating back into the Tulsa community. I am constantly looking for opportunities and partnerships that will benefit our residents. I love this town, and this is my way of giving back to it in the best way I know how." - Marcus Abernathy

Andrew Cassell

As of May 1, 2021, Sangha has a new full-time Director of Programming, and I am excited to introduce you to Andrew Cassell!  Andrew is a graduate of Bishop Kelley High School and Northeastern Oklahoma College in Miami, OK. He has a large family which includes his wife Candace, 4 kids and 4 step kids, who he loves spending time with. Andrew loves to work out and, in fact, spent the whole year of 2019 training in Strong Man Competitions - lifting weights in upwards of 800lbs.

Andrew helps oversee the day-to-day life at Sangha, and works closely with our residents, assisting them on their recovery journey and helping them become successful members of the community.

“I love Sangha’s vision and what it stands for - which is community. I really like the impact that Sangha has already made and will continue to make in helping these men become the best versions of themselves. I am fortunate that I get to be a part of it.” -Andrew Cassell

With the recent growth, we have added a new staff member.  We are excited to introduce you to Geoff Patterson:

“Born and raised in Tulsa, I have spent the last 8 years in Arizona and am thrilled to be returning to my hometown. I have 2 boys,12 and 2 years old. I have over 3 years sober and have spent the last 2 years working in Business Development for one of the nation’s oldest men’s treatment programs, the Prescott House. I have over 18 years of management and sales experience and have been recognized as a top manager and sales rep multiple times in my past roles. Looking forward to bringing that experience and my passion for life and recovery to Sangha. Honored to be on the team!” - Geoffrey Charles Patterson
