Drew Welch, RN

Registered Nurse, Program Director, Family Therapist

“He’s the best nurse I ever worked with. We worked together for 6 years at WestBridge and I am really lucky he agreed to work with me at Psych Garden. He’s thorough, conscientious, caring, humble, courageous, honest and wicked smart.”

Drew Welch is a licensed registered nurse & therapist with over 20 years of experience working with individuals with co-occurring disorders as well as their families. He has extensive training in evidence-based practices including motivational interviewing, cognitive behavioral therapies, family therapy, vocational rehabilitation and integrated dual disorders treatment and has supervised and taught others these skills.

Drew was at WestBridge Community Services for 7 years as their nurse care manager, team leader and national wellness coordinator. Prior to that he was the Nurse Manager for the Co-occurring Disorders Unit at Bournewood Hospital.

Drew has more than 20 years of sobriety. He understands how impossible recovery can seem and that no single path works for all. He knows the importance of education, support and hope. These days he uses all his training, experience and passion to help others feel freer, prouder and more connected. Sometimes 12 step approaches help, sometimes CBT, sometimes a focus on exercise and diet (Drew recently completed his first triathlon).
