Meet Our Team


Diedra Wells, LMFT

Hello, I am Deidra Kostelac, LMFT. I am a Licensed Marriage and Family Therapist practicing in Rancho Cucamonga, California. I received my Bachelor’s degree in Business Management and my Master’s degree in Counseling with an emphasis in Marriage and Family Therapy from the University of Phoenix.

I have been in the field for 8 years in various therapy settings. My specialties include addiction counseling with treatment of underlying mental health disorders or life challenges, such as co-dependency, depression, trauma, childhood issues, abuse or anxiety. I also assist with crisis interventions and improving self-motivation and self-esteem issues. 

My therapeutic style is eclectic. I utilize cognitive-behavioral therapy, solution-focused interventions, evidence-based practices, and experiential therapy. My goal as a Therapist is to provide a supportive environment and assist individuals, couples, and/or families to address their concerns by working together to process life’s obstacles. I strongly believe in empowering, educating, challenging, and supporting clients in their recovery and healing.
