Our Therapists

At One Heart Counseling Center, you are working with therapists who work on themselves.  That means you are being guided by someone who is willing to be in the trenches and do the things they are asking you to do.  You are working with therapists who know about the Human Emotional System. They can help you decode the information that wants to come forward and teach you about how to manage the discomfort that can sometimes come with experiencing your feelings.

Nikki Eby, M. A., MFT [LIC 85426], ATR-BC | Pronouns: she/her

Nikki is a Licensed Marriage and Family Therapist as well as Board Certified Art Therapist.  Nikki has over 10 years of experience working with children, adolescents, adults and couples in various settings working with trauma, grief, depression, anxiety, eating disorders, personality disorders and addiction recovery.  While her therapeutic style lands mostly on a humanistic and compassionate approach, she is extensively trained in evidenced based practices such as Dialectical Behavioral Therapy (DBT), Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT).  In addition, Nikki uses mentalization techniques with her clients, focusing on building the ability to reflect on or understand one’s own or others’ mental states that underlie patterns and ways of functioning.  Building skills like this result in an increased level of emotional regulation and, in turn, sense of well-being. Though Nikki works with a range of people from childhood to adulthood, she finds a great deal of success and richness in working with adolescents and young adults transitioning into adulthood.  Find out more about how Nikki works by reading her post: Why Do the Same Patterns Keep Repeating? Here’s One Explanation.
