Clinical Team
Jenni Busse MS, LPCC is the Clinical Director at Gratitude Lodge. Jenni oversees the clinical program and the clinical team at Gratitude Lodge as a whole. Jenni has worked in treatment for 14 years. Her background as a licensed therapist and her passion for helping others intersected with addiction recovery when she started working primarily in detox residential treatment. She always knew she would make a career out of helping people. The thing she enjoys most about working at Gratitude Lodge is seeing clients come back to life and make positive changes for themselves.
