VirtualAbout Me
I am a Licensed Clinical Social Worker with experience working with children, families, from infants to and elderly individuals. I enjoy working with all populations including LGBTQ, Military, Youth, Elderly and those struggling with anxiety and depression. I believe that we are our own best advocates and often have the solutions to our life's struggles, and at times just need a listening ear and some kind guidance. I look forward to working with you.
LCSW — Licensed Clinical Social Worker. An LCSW is a master's-level clinician licensed to provide psychotherapy and diagnose mental-health conditions. Social-work training brings a person-in-environment lens — examining how relationships, community, and access shape mental health alongside individual factors. Licensure requires supervised post-graduate clinical hours and a state board exam.
Our First Conversation
Our first session is a conversation, not an intake form. I'll ask what brought you in, what you've already tried, and what you're hoping changes. We'll figure out together whether we're a fit; if I think someone else on the team would serve you better, I'll say so.
From there, weekly 50-minute sessions are typical for the first few months. We'll check in periodically on what's working and recalibrate if something isn't. I send no homework you didn't agree to, and I don't grade you on between-session work — but I'll often suggest small experiments that move things forward faster than talk alone.
What You Can Count On From Me
The clients who've stayed longest tell me three things stand out. I track the throughline across sessions and bring it back into the room so a pattern you couldn't quite name becomes hard to miss. I push back when I think you're circling something rather than landing on it. And I treat fit as my problem to solve, not yours — if I think someone else on our team would serve you better, I'll say so before you've invested weeks finding out.
Who I’m Here For
My strongest fit is with adults in their 20s through 40s who look like they're handling life from the outside but feel persistently anxious, depleted, or disconnected underneath. That includes professionals running hot from burnout, partners working through the long aftermath of a rupture, and people processing grief or family-of-origin patterns showing up uninvited in adult relationships.
My Therapeutic Approach
I draw primarily on Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT). With CBT, I'm less interested in worksheets and more interested in helping you notice the thoughts that drive the loop you're stuck in — and then experimenting with what changes when you respond differently. ACT adds the piece CBT alone can miss: defining what actually matters to you, and using that as the anchor when life pulls in other directions.
For clients carrying trauma, I'm trained in EMDR and integrate it when it fits, with full transparency about what we're doing and why.

About
Hello, My name is Ashley Stacy and I am an LMFT, and a CODA- child of deaf adult. I am fluent in American Sign Language, and it is one of the reasons I became a therapist to be able to provide direct services to those who identify as deaf/ and hard of hearing. I specialize in working with those who have experienced trauma, such as secondary trauma, intimate partner violence, and family violence. I work with those who have anxiety/depression, and are experiencing certain life transitions such as a new career, becoming a parent, or caregiver for ailing parents.
