An attachment-focused therapist helping women break cycles and navigate relationships, motherhood, and life transitions with greater confidence and self-trust — and a supervisor devoted to developing the therapists who carry that healing forward.

Introduction: Why This Series Exists

Finding a therapist can feel overwhelming. You're not just choosing a provider — you're choosing someone you'll be vulnerable with, someone who will sit with your hardest experiences, and someone you can trust to guide healing.

This "Get to Know Your Therapist" series is designed to help you get a sense of the humans behind the work. Not just credentials — but style, presence, personality, and the kinds of clients they tend to work best with.

Today, you're getting to know Kirsti Reese, MA, LPC-S, founder and co-owner of Thrive Therapy Houston — a therapist whose work lives at the intersection of attachment science, perinatal mental health, nervous system healing, and deeply relational care.

She specializes in helping women understand not just what they are experiencing — but why it's happening in the first place, so lasting change becomes possible long after therapy ends. Her work focuses on attachment wounds, relationship patterns, perinatal mental health, and the major identity shifts that often accompany motherhood and other big life transitions.

The Heart of Her Work: How She Got Here

Kirsti didn't get to this work in a straight line.

She began in spaces where trauma was most visible — child advocacy centers, sexual assault resource centers, domestic violence shelters, and programs supporting children and families in crisis.

Early in that work, she noticed something that shaped everything that came after:

Even when children received support, the patterns often didn't fully change unless the larger system around them changed too.

So she moved upstream.

She began working with parents and caregivers, focusing on how relational patterns get passed down and repeated in family systems. But again, she ran into a familiar limit: many adults were already deep in chronic stress, burnout, or long-standing survival patterns that made change difficult to sustain.

So she moved earlier again — into perinatal mental health. Into pregnancy, postpartum, identity shifts, and the earliest moments where attachment patterns are actively forming. Not because one stage matters more than another, but because she became deeply committed to a single question:

Where can we intervene in the cycle so that changes last? What does sustainability actually look like?

Today, much of her work focuses on supporting women through relationship challenges, parenting decisions, fertility, pregnancy, postpartum adjustment, reproductive trauma, birth trauma, and the emotional transitions that accompany family building.

Alongside this clinical evolution, Kirsti's foundation in science has always been central. Originally on a pre-med track, she developed a fascination with physiology, anatomy, and how the body responds to stress. As she moved from working with children, to parents, to perinatal mental health, she found herself asking the same question over and over:

Why do people understand what needs to change but still feel stuck?

That search led her deeper into interpersonal neurobiology, attachment science, somatic psychology, and nervous system regulation. The answer wasn't a lack of motivation. It wasn't a lack of insight. It was that many of the patterns people struggle with live deeper than conscious thought. They live in the nervous system.

For Kirsti, therapy is where heart and science stop being separate ideas and become the same language.

One step further upstream than she ever expected

And then that same question — where can we intervene so change lasts? — carried her somewhere she didn't anticipate.

If a child's healing so often depends on the parent, and the parent's on their own earliest attachment, then whose healing shapes the most lives of all?

The therapist's.

A single well-supported, well-developed therapist touches hundreds — sometimes thousands — of lives across a career. If you want to break cycles at scale, you don't only treat clients. You develop the clinicians who treat them. You support the whole therapist — their skill, their nervous system, their own attachment history, and the person they bring into the room — so the care they give is sustainable, connected, and deep.

That is where Kirsti's trajectory has led. Everything she learned moving upstream through the cycle — child, to parent, to the perinatal window — pointed to the most upstream intervention of all: the development of the therapist. Today, alongside her clinical work with women and mothers, she pours much of her energy into supervising and developing clinicians. Because supporting the whole therapist may be the most powerful way she knows to help heal the world.

What She Helps People Understand: "Old Learning" and the 'Why' Behind It All

A core part of Kirsti's work is helping clients identify what she often calls "old learning." This includes:

  • The relational patterns you learned before you had language for them
  • The roles you adapted into inside your family system
  • The ways you learned to stay safe, liked, needed, or invisible
  • The attachment patterns that repeat in romantic relationships, friendships, parenting, and the relationship you have with yourself

From a nervous system perspective, these patterns are not flaws. They are adaptations. They made sense in the environment they were formed in. Using attachment theory, interpersonal neurobiology, and nervous system science, she helps what once felt confusing start to make sense — why certain relationships feel so activating, why boundaries feel difficult, and why the same patterns keep repeating despite wanting something different.

When people understand why their nervous system adapted the way it did, they stop feeling stuck — and start to reconnect to self-trust, realizing they could trust themselves all along.

Her goal is not just symptom relief. It's clarity, integration, and lasting change — the kind where clients leave not dependent on therapy, but equipped with an internal map of their own patterns, so they can keep building healthier relationships and breaking cycles in their own lives and families.

What It's Like to Work With Kirsti

Working with Kirsti is often described as warm, deeply relational, and surprisingly real. There is space for depth — but also space for humor.

Kirsti pays close attention to what is happening in the moment — emotionally, cognitively, relationally, and in the nervous system. She helps clients slow down enough to notice patterns as they unfold, not just after they've already taken over. Sessions are collaborative: you're not being analyzed, you're being partnered with. There is grounding, curiosity, and a sense of "we're in this together" that helps even difficult material feel more manageable.

Who She Works Best With

Kirsti works best with women who are highly motivated and ready for meaningful change, even if they don't yet know exactly how to get there. This often includes:

  • Women navigating attachment wounds and relationship patterns that keep showing up in adulthood
  • High-achievers tired of over-functioning, people-pleasing, and carrying everyone else's emotional needs
  • Women who have spent years being the responsible one, the helper, the fixer, or the strong one
  • Cycle breakers committed to creating healthier relationships than the ones they inherited
  • Mothers who want to heal their own history while building secure attachment with their children
  • Women preparing for motherhood or adjusting to pregnancy, postpartum, and family-building transitions
  • Women navigating fertility challenges, reproductive trauma, miscarriage, birth trauma, or postpartum adjustment
  • Women navigating major life transitions and identity shifts, including perimenopause and menopause
  • Individuals seeking deeper self-trust, healthier relationships, and greater emotional security

She especially resonates with people who are ready not just to feel better — but to understand themselves differently, so change actually sticks.

A Nervous System + Body-Based Approach to Change

Kirsti integrates evidence-based trauma therapies with body-based and attachment-focused work, including:

  • EMDR
  • Somatic Experiencing (SE)
  • Trauma-Focused Cognitive Behavioral Therapy (TF-CBT)
  • Emotionally Focused Therapy (EFT)
  • Interpersonal Neurobiology
  • Attachment-Based Therapy

Her approach is grounded in a simple but powerful belief: insight matters — but it's not enough on its own. Lasting change requires the nervous system to experience something different, not just understand something differently.

Developing the Whole Therapist: Where the Work Is Leading

In addition to her clinical work, Kirsti is a Licensed Professional Counselor Supervisor (LPC-S), Registered Play Therapist Supervisor (RPT-S), and EMDRIA Approved Consultant — and this is where her trajectory has ultimately settled. A significant and growing part of her work now includes:

  • Supervising and mentoring therapists toward licensure and certification
  • Providing EMDR consultation and clinical guidance
  • Supporting clinicians in developing trauma-informed, nervous system-aware practices
  • Person-of-the-therapist work — helping therapists grow not just technically, but personally and relationally

Her deeper goal is simple, and it's the natural endpoint of everything that came before:

To develop therapists who can do sustainable, connected, and meaningful work — supporting the whole therapist so that clients everywhere benefit from better care, and healing ripples outward into the world.

Life Outside the Therapy Room

Kirsti is deeply human outside the therapy room and wouldn't have it any other way. These days, most of her life revolves around family, nature, and trying to keep up with two small children who seem determined to turn every outing into an adventure. You might run into her:

  • At a playground or play café chasing toddlers while drinking coffee that has almost certainly gone cold
  • At a Barre or Pilates class — because movement, good music, and gym childcare feel like a gift from the universe
  • Walking trails at the Houston Arboretum or Armand Bayou, spotting turtles with her kids
  • Tending her garden and experimenting with herbal teas made from whatever's growing that season
  • Getting completely distracted by penguins (and air conditioning) at the aquarium
  • Browsing the library with a stack of books she probably won't finish before checking out another

She is a lifelong traveler, plant enthusiast, scuba diver, reader, and nature lover who firmly believes healing happens both inside and outside the therapy office. Her long-term dream is to create immersive healing retreats that combine therapy, yoga, forest bathing, and plants — helping people reconnect with themselves, their communities, and the natural world.

What She Wants You to Know Before Starting

You don't need to show up with your own map. And you don't need to know exactly what you need before you begin. A big part of the work is learning — together — how your system adapted, why it adapted that way, and how to create space for something new. As long as you bring the motivation, she has plenty of ways to help you get where you want to go.

Closing: You Don't Have to Break the Cycle Alone

So much of what brings people into therapy isn't just pain — it's patterns. The same relationship dynamics. The same boundaries being crossed. The same burnout cycles. The same attachment wounds that keep showing up despite your best efforts to do things differently.

Kirsti's work is about helping you understand those patterns at their root — so you can stop repeating them and start living differently. And increasingly, it's about helping the therapists who do this work do it well, sustainably, and from a grounded, connected place — so that healing reaches further than any one office ever could.

If this resonates — whether you're a client ready to begin, or a clinician looking to grow — you're invited to reach out when you're ready. We'll start exactly where you are.
