Chelsey Pierce, LMSW

Willow House Residential Program Director in Olean, NY

Continuing to learn and grow in my education and treatment of substance abuse has become a passion of mine.  I most recently graduated from Edinboro University with my master’s in social work.  I received my CASAC 2 (Credentialed Alcoholism and Substance Abuse Counselor – Advanced) in 2020 and I am a Licensed Master Social Worker (LMSW).  I enjoy reading, hiking, playing with my dog, Ellie and most importantly spending time with my baby boy, Finnley.

Sean is a graduate of Army Ranger School and retired with over 20 years of service completed. Since retirement, he has become a Certified Recovery Peer Advocate (CRPA) and attained a degree in Addiction Counseling, was the Co-Founder of ROCovery Fitness and has launched AIR – Adventures in Recovery at CASA-Trinity. Being active and connecting with people is what he loves to do. With his dog, Neya, by his side, they have been able to expand the AIR program across multiple counties in New York State. Getting people out into the woods, on the water, and together to gain connection, support and learn a healthier lifestyle in recovery is Sean’s passion.
