I’m really glad you’re here.

​

You found your way here, so there’s a good chance something isn’t working the way it used to, or things just feel harder and heavier than you can manage on your own right now.

​

You might be feeling overwhelmed, stuck, misunderstood, or struggling to keep up, whether you appear to have it together or feel like you’re barely holding on.

​

I work with teens, adults, families, first responders and veterans who want to better understand themselves, build emotional awareness, and live in more grounded, intentional ways.

​

I’ve done this work myself, rebuilding my life from scattered pieces, one step at a time. I still show up for it daily.

​

Change doesn’t happen all at once. It happens through small, consistent steps, and here, you don’t have to do it alone.

​

​Solid Ground Trauma Counseling & Addiction is my developing professional brand; it is not an independent private practice.

Hey there, thanks for stopping by! I'm a trauma-informed, recovery-oriented therapist who works at the intersection of emotional pain and behavioral patterns. I help clients understand the “why” behind their reactions and build the internal steadiness needed for real change.

​

My clinical approach blends neuroscience, trauma work, and addiction-informed treatment. I work with people who feel pulled between what they want and how they are actually coping. These are people who genuinely want to move forward but find themselves relying on old patterns, survival strategies, or coping mechanisms that no longer serve them.

​

While I bring empathy and humanity into the room, I also bring structure. I help you slow down, understand your internal experience, and separate trauma-driven reactions from recovery needs. My style is warm, direct, and collaborative. We do not just talk about what happened. We explore how your system learned to respond and how to shift those responses over time.

​

My background in clinical psychology and human development, along with specialized training in trauma, addiction, stress, and behavior, informs everything I do. My lived experience deepens my empathy, but it does not guide the session. Your experience does. My role is to offer a grounded, nonjudgmental space where you can explore your patterns, gain clarity, and build tools that strengthen both your recovery and your overall wellbeing.

​

Solid Ground TCA exists to support one central purpose: helping you find steadiness inside yourself, even when life feels overwhelming.

​

Trauma & Abuse Recovery

Support for trauma, complex trauma, and abuse. We slow things down, make sense of your reactions, and help your system feel safer over time.

Brain & Body Connection

Trauma and stress live in the body. We work with nervous system awareness, grounding, and patterns shaped by past experiences.

Interpersonal Connection

Relationships reflect how we learned to connect and protect ourselves. We explore communication, boundaries, and attachment patterns.

Addiction & Recovery

Recovery is more than stopping a behavior. We address urges, patterns, shame, and the emotional roots of compulsive coping.

Inner Harmony

Many people feel pulled in different directions inside themselves. We explore the parts of you that want comfort and the parts that want change.

Generational Healing

Family patterns and survival strategies move through generations. We work to understand them and interrupt what no longer fits.

Change doesn’t happen by chance; it happens by choice. Change is hard. Staying stuck is hard.

First Responders

As the spouse of a veteran, I understand how service shapes a person’s nervous system, relationships, and daily life. I also understand how hard it can be to ask for support when you are trained to keep moving and stay in control.

​

I offer trauma-informed and culturally aware care for veterans, first responders, and their families. Together, we look at the silent burdens you carry. These often include chronic stress, irritability, emotional numbness, hypervigilance, difficulty relaxing, and the strain of shifting between duty mode and home life.

​

I offer extended 90 minute sessions to create the space needed to process experiences without rushing. My focus is on grounding, clarity, and practical support for the complex realities of military and responder life.
