I’m a licensed marriage and family therapist who specializes in working with individual adults. I support clients navigating ADHD, neurodivergence, emotional regulation, relationship patterns, identity, and life transitions. My work is trauma-informed, LGBTQ+ affirming, and grounded in the belief that therapy can help you better understand yourself, strengthen self-trust, and the clinical belief that any person can change course in life at any time.
I draw from approaches such as EFT, IFS, ACT, and integrative experiential techniques, tailoring our work to your unique needs and goals. Together, we’ll explore emotions, patterns, and strategies that help you feel more grounded, resilient, and connected to yourself and the relationships that matter most.
Larissa Theison is a licensed clinician with over 15 years of experience helping individuals navigate life's challenges. Trained in EMDR, DBT, and person-centered services, she specializes in supporting clients facing many struggles.

I am able to evaluate and make diagnoses, and/or support existing diagnoses and work with you for a 'best-fit' solution to your needs. So many come from a past of being told they are 'X, Y, Z" and often misdiagnosed or underdiagnosed.
My goal is to help find a good treatment start point that resonates with you and provide evidence-based treatment to support your needs, goals, and desires to bring relief and remission, joy and hope.
All options on the table including progressive medication management, psychotherapy and counseling, or referrals for other modalities including deepTMS.

Hey! You’re seeking help because it is needed. That’s huge! Many people don’t seek treatment or therapy but you’re already on this path. Some folks don’t find the path. You’ve got some idea of what you need and are ready for someone to be along with you on this journey. We both know humans succeed in a team not so much when we are alone. First, give yourself credit because it takes a lot of courage to not do things alone and to be willing to open up to someone you do not know. Your courage is where our journey together starts. It would be an honor to be a part of your team in life, for life!


Headway makes it easier to find support for overcoming addiction — from finding the right provider, to understanding costs, to scheduling with ease.
Finding addiction therapists in Overland Park starts with identifying the kind of support that fits your needs. Addiction care can include support for alcohol use, substance use, gambling, compulsive behaviors, and co-occurring concerns like anxiety, depression, or trauma. As you compare therapists, look for listed experience with addiction counseling, substance use, motivational interviewing, cognitive behavioral therapy for substance use, harm reduction, or medication-assisted care coordination. Some people also work with a prescriber as part of their care team.
In a mid-size market like Overland Park, you may find local therapists near home, work, or nearby Kansas City, along with virtual options that expand your search. Recovery can involve changes over time, so it helps to choose a therapist whose approach feels steady, respectful, and nonjudgmental. You can also compare appointment availability, session structure, and whether a free phone consultation is offered. Reading therapist bios can help you understand how they talk about addiction care, harm reduction, relapse prevention, and related concerns before you book.
Addiction therapy in Overland Park can be expensive without insurance. Using in-network insurance is one of the most reliable ways to reduce session costs and understand what you may pay before care begins. Headway helps you search for therapists who are accepting new patients, partners with a wide range of insurance plans nationally, and shows estimated out-of-pocket costs after you enter your insurance details. You can browse therapists, review bios, and book directly when you’re ready.
