My name is Ashley Beech-Mavrantzas, and I've been in mental health practice for 10 years. I specialize in Mood disorders, Bipolar disorder, and Borderline personality disorder. I also have experience in grief therapy. Furthermore, I use many modalities to treat these disorders such as DBT, CBT and EMDR. Additionally, I use different eclectic modalities based on the client's needs. The best method is client-focused to ensure that I am treating you accurately.

Get to know me

In our first session together, here's what you can expect

In our first appointment, I will ascertain what your needs are and identify topics that need to be addressed. I hope to establish a strong rapport between us and understand what you need from a therapist. Then we will begin to explore how I can assist you in your mental health journey. We will work as a team to address and accomplish your goals.

The biggest strengths that I bring into our sessions

I offer clients 12 years experience, and I am an open and non-judgmental therapist. I believe that mental health is as important as physical health.

The clients I'm best positioned to serve

I work best with clients who suffer from depressive and personality disorders. My clients are usually in need of emotional regulation and distress tolerance. They are also in need of coping skills to manage their behavior.
