Ashten Carrin Trimble

Licensed Professional Counselor, CCTP

I love helping people work on different relational conflicts within their family system. I deal a great amount with co-parenting in being able to help parents productively communicate after separation or divorce. My passion is working with parents and children affected by Parental Alienation. I work with kids that experience a divorce in their family and help them learn new coping skills in order to appropriately handle these new transitions in their life. I also help parents work through reunification counseling with their children with a goal of having a healthy sustainable relationship with their children at the end of the path.


As a Marital and Family Therapist, I specialize in couples/marital/premarital therapy. I am also a Certified Clinical Trauma Professional trained in providing effective treatment to clients that have struggled with trauma of any kind. Most importantly, though, is my passion to help these individuals express their trauma narrative from their own perspective!


I have had clients that range from age 3 to 80+ and I truly believe that counseling and building a therapeutic relationship with the right therapist can benefit anyone! It has personally helped benefit me when I was younger and I would love to pay it forward and give back by helping others a well!
