GenTox Wellness Clinic is here for you and your health.
Our mission is to empower each patient with knowledge to effectively make educated choices in their own healthcare, plus encourage each patient to communicate with our providers and expect in return the best quality of care for their body, mind, and spirit.
About the Clinic
GenTox Wellness Clinic was founded by Mindy Middleton Bittner to meet a growing need she recognized through her work at GenTox. What began as a commitment to support clients through drug testing has grown into a comprehensive Addiction and Mental Health Clinic dedicated to helping individuals on their journey to recovery and wellness.
At GenTox, we believe in treating the whole person—not just the symptoms. Every patient is valued as an individual, not a number or statistic. Our team of trained professionals is committed to providing compassionate, evidence-based care that empowers you to heal, grow, and thrive.

Madison Giles, LMHC
Therapist
Hi, I’m Madison, or “Maddie”, Giles—a Licensed Mental Health Counselor based in Evansville, IN with a passion for helping people heal, grow, and feel understood. I work with individuals ages 8 and up, offering support through life’s toughest moments—whether it’s trauma, anxiety, mood changes, substance use, or behavioral challenges.
I specialize in trauma-informed care and use a mix of evidence-based approaches including CBT, CBT-TF, DBT, ACT, Solution-Focused Therapy, Motivational Interviewing, Mindfulness, and Person-Centered techniques. I’m also an LGBTQIA+ ally and create a safe, affirming space for all persons and identities.
With experience in both inpatient and outpatient settings, I’ve had the privilege of working with diverse individuals in underserved communities. I earned my BA from Franklin College and my MA in Mental Health Counseling from Indiana University–Columbus, and I’m committed to ongoing growth—as a therapist and as a human.
Outside the therapy room, I’m an Indianapolis native who finds peace in nature, joy in camping trips, and unconditional love from my two pets: Luigi the cat and Millie the dog. On Sunday afternoons, you’ll probably find me watching football as it counts as self-care (because it totally does).
Whether you’re navigating a new challenge or unpacking old wounds, I’m here to walk with you—at your pace, in your way.
