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.
