See what our patients are saying about Nicole Harker

I am beyond grateful for the support and care I received from Nikki. From the very beginning, Nikki created a space that felt safe, welcoming, and free of judgment. With all honesty, I have never enjoyed going to group therapy’s, not until experiencing Nikki’s group. She always led our group with compassion, patience, and genuine empathy, always encouraging growth while honoring where each person was emotionally. After her sessions I always felt empowered to continue putting in the work for myself. Thank you Nikki for helping me in my healing journey. You’re the best!
