We all have things in our lives that we wish hadn’t happened. Challenges happen all the time, and they’re part of what make us human. Those challenges can change how you view the world, and how you view yourself–sometimes in a way that makes it hard to respond the way you want to when new challenges arise. But you don’t have to continue living under the weight of these difficulties. You have the capacity to adapt to new information, and to gain new insights that help you to view your past and present differently. I believe that through the work and healing done in therapy, a better future can be created.
I work with adults to provide individualized treatment designed to increase your current capacity to regulate your emotions, and to get at the root cause of your current struggles. I specialize in eye movement desensitization and reprocessing (EMDR), as well as systemic trauma models designed to find and create supports and safety in your environment.
I received my Masters in Social Work from the University of Denver in 2013, with a certificate in Interpersonal Trauma Studies. I practiced in a community mental health setting for seven years, and I have been in private practice for the last four years. I became an approved EMDR consultant in October 2022, which I provide to clients each week in addition to providing consultation for other clinicians working towards EMDR certification.
