Melanie Creger

Melanie Creger is a licensed professional counselor, clinical substance abuse counselor and certified social worker. She has worked in the counseling and psychological services field since 1990.

“I believe everyone has strengths and can heal and thrive. Therapy does not have to add to trauma. I add a good dose of humor to help you feel successful on your journey. Therapy is most effective when it is collaborative and tailored specifically to each individual. I encourage everyone to build a strong and positive support system.

“I am grateful for the opportunity to work with people to reach their goals and improve their lives. I help people heal from the past and take charge of their lives in a different way. I primarily use cognitive behavioral therapy to help clients make changes, knowing they are doing the best they can. I provide remote virtual counseling and EAP services. All are welcome!”
