Gwendolyn Casella

Director of Detoxification and Chemical Dependency Programs, Thousand Oaks

“If I can make a difference in one person’s life, restore hope to an addict’s heart, my job is done. One person can make a profound difference.”

After Gwendolyn got clean and sober in 1997, she worked at Cri-Help, Inc. for over a decade in a variety of direct care and administrative roles while attending Drug and Alcohol Studies at Pierce and Mission Colleges. Since 2002, Gwen has been tied to the recovery community through her considerable experience as a sober coach and by conducting “extreme interventions” (defined as “recovery by any means necessary”). She has her own business, Recovery Services Unlimited LLC and, notably, was featured on A&E’s “Relapse, the Sober Coach Chronicles.”

Identifying integrity as the underpinning of her approach, Gwen considers herself very lucky to be trained by some amazing mentors for whom she has always had a tremendous respect.

Having worked at several treatment facilities, Gwen now passionately devotes all of her professional efforts to her role as Detox Program Coordinator at La Ventana. She believes she was meant to do this work and loves doing it. When Gwen is not working, she enjoys spending time with her family and singing her heart out.

Michelle Kunzelmann

Biofeedback Specialist
Michelle believes that neuroscience is at the center of healing. While training to become certified she experienced her own transformation and at that time she knew she had found her life’s passion. Because of her own struggle with Depression, Trauma, and complicated reactions to medications she prefers a natural approach to healing. Michelle’s favorite quote is “every brain deserves this chance”. She begins each day eager to help others, and with gratitude for the healing in her own life. Michelle has worked with trauma survivors and with adults who suffer chronic emotion dysregulation, as well as co-occurring eating and substance use disorders. The most common issue clients struggle with is anxiety, which is substantially reduced in the first session or two. Her focus is in helping those new to Neurofeedback to understand the process, benefits, and ensuring that they feel safe as they begin their journey. She also emphasizes the importance of educating clients about brain health as they continue with treatment.
