Cathy Knezevich, M.Ed., PCC

Ms.Knezevich’s goal as a Licensed Professional Clinical Counselor is to help people live a more fulfilled life, whether they are managing emotional issues or life challenges. She works with older teens, adults and seniors; individually, as couples and families. She also runs a Dialectical Behavioral Therapy (DBT) intensive outpatient program (IOP) for adults with more difficult emotional, behavioral or life challenges. Ms.Knezevich’s style is to balance acceptance with change to help people explore feelings and behavior patterns and make significant changes in a supportive environment. Some specialties are EMDR (with a professional referral), a powerful therapeutic technique originally designed for trauma survivors; mindfulness and meditation, cognitive behavior therapy (CBT), DBT, art therapy, and solution focused therapy.

Ms.Knezevich obtained her Master’s Degree from Cleveland State University, in community and agency counseling. She has worked in private practice since 1994 and has established 2 DBT IOP therapy programs as well as co-facilitated a dual diagnosis IOP. Ms.Knezevich has advanced training in critical incident stress debriefing and has volunteered as the assistant clinical director of the Lake-Geauga Critical Incident Management Team for 18 years. She has worked as a social worker and case manager at Laurelwood Hospital, a therapist in the outpatient Victims Resource Program, and started her career as a volunteer for the program.
