Shana Anderson, LPC

Shana Anderson, LPC

Licensed Professional Counselor

I believe that our experiences help to inform us about the life that we want to create for ourselves. In doing this work, I believe that all people have a purpose and that we should demonstrate compassion towards ourselves and others as we work toward discovering it.

As your counselor, my approach is to be a kind and compassionate presence, while also using humor as a healing tool to help you discover your purpose, rediscover who you are, or assist you in defining a new you in an empathetic and curious way.

We co-create an environment of exploration by finding ways to encourage authenticity in our healing space while exploring root causes of learned behaviors. During our process, we can also do work to untether you from patterns and thinking that no longer serve you while working toward a redefined future. We do this work by gently challenging these patterns, and by providing direct feedback in moments in which we can alter these thought processes. I strongly believe in the practice of empowerment, solution-focused strategies, and trauma-informed mindfulness as we go through this journey of aligning our mind, body, and spirit.

I have experience working with people from all walks of life, and I really enjoy doing work with people who are first-time clients, college students, or those who have concerns with Anxiety, Depression, Trauma, Relationships, Divorce, Non-Traditional Relationships, Spirituality/Religion, Self Esteem/Self Compassion work, Identity Development, and Adjustment Issues. 

I received my formal education in Clinical Mental Health Counseling , as well as Adult and Higher Education from Northern Illinois University. Go Huskies!

In addition to my clinical care career exploration, I have worked in Colleges and Universities for over a decade supporting advocacy efforts geared toward intimate partner violence, holistic need care through case management services, mental health crisis care, university administrative efforts, and classroom teaching.

Outside of the therapeutic space, I enjoy spending time with my loving Husband and our furry baby Ella. I love all things Wizard of oz, finding excuses to go to Target, laughing, cooking, and serving in Ministry.

It is my greatest honor to support you on this wellness journey, and I am looking forward to seeing you in session soon!
