Leadership

Sierra Burton

MA, LMFT #50154

Clinical Supervisor · Founder and Chief Visionary Officer

  • I am passionate about therapy because therapy saved me, changed me, challenged me, grew me and helped me become who I am today. In college I worked towards a law degree, then vet medicine, but something continued to draw me back to psychology and helping people. In my opinion and personal experience, therapy works. I have seen couples, families and individuals come through some amazing journeys. My approach is very interactive while providing a non-judgmental place for free expression of thoughts and feelings. ​


    I am currently owner and director for Sierra Therapy Center in beautiful Nevada County. I also serve on CAMFT Legislative Committee and I LOVE to supervise new associates and graduate students! Prior to this, I was the Clinical Director for a residential children's program. I left this position knowing that my true purpose was to work every day with my clients. We are a growing therapy center aimed at improving personal lives and family dynamics.


    I was born and raised in Grass Valley (graduate of our local Nevada Union), I completed my undergraduate degree in psychology at California State University of Sacramento and earned my Masters in Marriage and Family Therapy (MFT) from Chapman University. 

    When I'm not working with my clients, I enjoy spending time with my family of 5 - cooking, gardening, ballet, meditation, and best of all - being a wife and mom.

  • I consider therapy to be a place to find and explore your truth. Therapy is a place to grow your inner strength, build new skills, learn to set boundaries, and to find and assert your voice to move through the challenge’s life has presented. This is a journey we take together.  I will provide guidance through a client-centered and strength-based approach to meet you where you are on your path. I will utilize a cognitive behavior approach and evidence-based practices to increase insight and build mastery to empower you to independently implement your skills and develop natural support systems


    I'm a Licensed Marriage and Family Therapist, completing my degree at Brandman University in 2015. For the past 9 years I've provided support to youth and their families who are in residential care with an intensive therapeutic environment.  This has provided an opportunity to support their personal growth to manage symptoms related to trauma, struggle with Anger Management, Depression, Anxiety, Bipolar, ADHD, DMDD, ODD, and Parent-Child Relationship Problems.  I enjoy working with married or divorced parents to assist then in learning to communicate with each other in order to parent a child with healthy boundaries and consistency. I understand how to assist in functioning within the home, school, and community environment. I have familiarity and insight into working with systems of care related to CPS, Probation, IEP's, and Managed Care. 


    I look forward to taking this journey with you, triumphing through the valleys and celebrating at the peaks.
