About Us

"I always knew I needed to help others, and it was always going to be through counseling. I just took the long, windy road to get here," Sandi explains, on how Key2Happiness Counseling came to fruition. "And I tend to have big ideas. Some good, some less than. This was a good one."

She launched Key2Happiness Counseling as a way to provide the kind of care she felt was missing, all while working in the Mental Health Administration. What started as a small practice to help clients in need quickly grew as colleagues joined her mission.

With years of experience in mental health, Sandi’s passion for her work has always been unwavering. When she’s not counseling, you might find her sailing or enjoying the peace of being near water. A music enthusiast, Sandi immerses herself in the world of sound whenever possible. She also has four beloved dogs, one of whom shares her workspace and offers some noisy but supportive company!

Sandi specializes in trauma, toxic stress, depression, and anxiety, offering compassionate support to those facing life’s challenges. Her work started with children and adolescents, focusing on helping them navigate difficult emotions and improving communication within families. She has also worked with adults to enhance their overall quality of life, believing strongly that mental health care is just as important as physical health.

Currently, Sandi offers virtual sessions to clients throughout Michigan, providing the same level of care and dedication to anyone who needs it. She believes everyone deserves a counselor who listens, offers non-judgmental support, and helps them through life’s challenges.

Meet Sandi Stasko, MS LPC – Owner of Key2Happiness Counseling.

Hello.

I'm Dorian (they/them/theirs) and I'm the administrative assistant for Key2Happiness Counseling! I'm thrilled to help connect you with one of our excellent counselors!
When I'm not managing phone calls and emails for K2H, I'm spending time with my partner and pets, playing some retro video games, tending plants, or tinkering with some computers.

Hope Tinholt

Practice Manager

Hi, I’m Hope Tinholt (she/her), a licensed clinical therapist at Key2Happiness. I'm accepting clients of all ages using our telehealth platform.

Hi! I’m Hope Tinholt, born and raised in West Michigan, I still get to call West Michigan home. I attended Grand Valley State University for both my undergraduate and graduate schooling and have been practicing therapy for 4 years. When I’m not working, I enjoy spending time with family and friends, running with my dog, playing pickleball, doing puzzles and watching sports. Go Lions!

I have experience working with children, teens and adults who experience a variety of challenges such as autism, anxiety, depression, self-esteem and trauma. I’m certified in Dialectical Behavioral Therapy (DBT) and Trauma Focused Cognitive Behavioral Therapy (TF-CBT) and bring in techniques from CBT and IFS. In our sessions, I strive to provide a safe, non-judgmental space, meeting you where you’re at, to help you through your healing journey. I look forward to working with you!

I am grateful for the opportunity to provide affirming healthcare to members of the LGBTQ2SIA+ community. I use an integrative humanistic approach in sessions that is collaborative and affirming. My favorite part of being a counselor is getting to know my clients and helping them discover their strengths. I specialize in gender dysphoria, monogamous and polyamorous relationship difficulties, trauma, and identity issues.

When I am not working, I love spending time with my partners, chosen family, and many pets (you may see one of my rabbits or cats while on telehealth with me). I am a voracious plant parent with over 30 houseplants and a lovingly cultivated native plants garden outside. I love watching movies (horror especially), reading, and playing cozy video games like Stardew Valley. I also enjoy board games and role-playing games like DND.

Available via telehealth Monday-Thursday 10 am-5 pm.
Waitlist for new weekly/bi-weekly therapy clients.
Current availability for clients who need WPATH letters of support for gender-affirming services.

Sam Darrow, LPC

Thanks for stopping by! My name is Sam (they/them/theirs) and I am a queer, non-binary, neurodivergent counselor.

Rachel Watson, LMSW

Hi! I’m Rachel Watson (she/her), a licensed clinical therapist dedicated to helping you or your child feel seen, understood, and supported.

If you’re exploring therapy for the first time or returning to it, I’m here to make this a space where you can find what you need. I work with clients ages 10 and up across Michigan through Telehealth, and I also offer in-person sessions at our cozy Allendale office.

Originally from Michigan’s beautiful Upper Peninsula, I still love heading back up north to visit. Grand Rapids is now home, where I enjoy life with my family and pets. Outside of work, you can usually find me swimming, puzzling, exploring local restaurants, or spending time in the garden.

My passion lies in supporting clients as they navigate life’s challenges and heal from past traumas. With experience working with children, teens, and young adults, I’m well-versed in helping clients with a wide range of issues, from anxiety, trauma, and school-related stressors to self-esteem struggles and life transitions. I’m nationally certified in Trauma-Focused Cognitive Behavioral Therapy and often incorporate techniques from CBT, IFS, and DBT, tailoring each approach to best meet your needs.

I believe in creating a warm, judgment-free space where you can safely explore emotions, build self-awareness, and develop skills to move forward in a healthier, happier direction. Whether you're here for yourself or your child, I look forward to working together and helping you find healing and growth.

Aubrey East

Hi! I'm Aubrey East (she/her), a limited licensed clinical therapist, and I’m passionate about helping you or your child feel heard, supported, and understood.

Whether you're just starting therapy or returning after a break, my aim is to provide a welcoming environment where you can feel at ease and find the support you're looking for as we work together. I offer Telehealth sessions to clients aged 12 and older throughout Michigan, as well as in-person appointments at our inviting Allendale office.

I am originally from the east side of Michigan but have called the west side home since pursuing my undergraduate degree in psychology at Hope College (Go Dutch!) and my Master's degree in Social Work at Grand Valley State University. Having been a competitive swimmer for 13 years, prioritizing health and wellness is a passion of mine. Outside of work, you can find me reading, swimming, exploring new places with friends, and spending time by any body of water!

I have experience working with young adults and college students, and I am dedicated to helping clients navigate a variety of challenges, from anxiety and trauma to self esteem struggles, school/sport related stress, and life transitions. In my therapeutic approach, I often combine a client-centered and strengths-based methodology with techniques from CBT, ACT, and family systems, tailoring my approach to each individual’s unique needs and circumstances.

I strive to create a supportive, conversational space for my clients. By focusing on your strengths and resilience, I hope we can facilitate personal growth and healing in a compassionate environment that honors your unique journey.

When life feels overwhelming, we often try to “think” our way through it. But the truth is—healing isn’t just a mental process. Our bodies carry the stories of our experiences: the racing heart during anxiety, the tight chest when we’re holding back tears, or the tension in our shoulders after a stressful day. Let's work together to invite the body into the conversation. If you are feeling stuck, disconnected I can offer a way to reconnect with yourself-not just in your thoughts but in your whole being. I provide a supportive, nonjudgemental space where healing and growth can begin.

I work with individuals fourteen-adult using a collaborative approach that honors your unique story. My style is warm, grounded and evidence-based. I integrate techniques from CBT, mindfulness and somatic informed care depending on your needs.

My goal is not only to help you cope but to help you connect more deeply with yourself, gain clarity and feel empowered in your life. Therapy is not about fixing what is broken but uncovering your strengths, reclaiming your voice and finding peace.

I have years of experience working with all ages experiencing some of their lowest lows but also the privilege of celebrating with them some of their highest highs. I have a Master's Degree in Social Work from Grand Valley State University. I am originally from Illinois but have called West Michigan home for over 20 years. When I am not working, I enjoy spending time with my family, reading thrillers, hiking and playing volleyball.

If you have questions or would like to talk more to see if I am a good fit, please reach out and we can schedule a consult call.

Lauren Rouwhorst

Hi! I’m Lauren Rouwhorst, a licensed clinical social worker, passionate about providing a safe place to allow you to be present with yourself.

I believe healing happens through both mind and body experiences, and I’m here to support you in finding ways to feel more connected to yourself and at peace with the world around you.

I work with individuals ages 11 and up, offering a warm, supportive space to explore life’s challenges and build lasting tools for growth. My approach draws from CBT, somatic therapy, motivational interviewing, and uses a humanistic lens to create a safe, non-judgmental environment for insight and meaningful change.

As a new mom, I understand the complexities of postpartum life. I offer a space for new parents to process, cope, and reconnect with their evolving identity. My lived experience with chronic pain and neurodivergence brings empathy and a holistic, mind-body perspective into our work together.

Whether you’re navigating negative life events, managing stress, or finding your footing as you step into a new phase of life, I’m here to support you in your journey toward growth, healing, and fulfillment. Together, we’ll move at your pace and focus on what matters most to you.

Austin Bastien

I’m a Limited Licensed Professional Counselor (LLPC) and recently joined Key2Happiness Counseling to continue supporting individuals on their journey toward growth and healing. I’m passionate about creating a safe, collaborative, and non-judgmental space where clients can feel seen and empowered to work toward their personal goals.

I have experience working with adolescents, young adults, and adults navigating anxiety, ADHD, self-esteem challenges, relationship concerns, life transitions, and problematic sexual behaviors. I also welcome both heterosexual and queer couples and am continuing to expand my experience in this area.

I earned my Bachelor’s degree in Psychology from Grand Valley State University and my Master’s in Counseling from Western Michigan University.

Outside of the therapy space, I enjoy spending time with family and friends, being outdoors, staying active, playing video games, baking, and horticulture.

Alyssa Sebesky

Hi! I'm Alyssa. I have four years of experience supporting youth, families, and individuals. I am deeply committed to helping clients feel seen, supported, and empowered. I strive to create a supportive, honest, and motivating space where clients feel understood and encouraged to move toward healing and long-term wellness.

I utilize Cognitive Behavioral Therapy and Motivational Interviewing to support healthier thinking patterns and meaningful change. Whether you are facing mental health challenges, relational struggles, lifestyle changes, or trying to determine the next right move, my approach is direct yet compassionate—and my promise is to sit with you, no matter how difficult life feels, as you work toward healing and growth

Andrew Harwood

Hi — I’m glad you’re here!

I believe therapy should honor your whole experience — your body, history, culture, identity, and nervous system. I specialize in complex trauma, identity work, trauma-related patterns often labeled as borderline personality disorder, late-diagnosed neurodivergence, chronic illness and disability, gender dysphoria, and religious trauma.

Many people come to me after years of feeling misunderstood, mislabeled, or marginalized. Your cultural background, spiritual beliefs, neurotype, and personal framework for meaning are welcome here. My work is trauma-informed and body-aware. Drawing from somatic practices and polyvagal theory, I help clients understand how their nervous system learned to cope and how to build more safety, regulation, and self-trust. I also integrate depth-oriented, narrative, and decolonizing approaches.

Therapy moves at a pace that respects fatigue, sensory needs, and fluctuating capacity. Sessions with me are collaborative, consent-based, and guided by your nervous system. If you’ve felt unseen or pressured to fit into systems that weren’t built for you, my goal is to offer a space where your story is met with care. Also, I have a cat named Cooper who serves as my “assistant therapist” — they are great at sitting nearby during sessions and offering quiet comfort.

If you’re ready to explore your story, feel safer in your body, or simply have a space to be seen without judgment, I’d be honored to walk alongside you in this work. Healing doesn’t have to follow a set path — we’ll move at a pace that feels right for you, honoring your experience every step of the way.

Kristin Matvichuk

Hello! I am a Limited Licensed Master Social Worker (LLMSW) with a passion for supporting children, families, and individuals through life’s challenges. I earned both my Bachelor’s (2020) and Master’s (2021) degrees in Social Work from Grand Valley State University and have been working in clinical counseling since 2021. In 2023, I expanded my work into school-based social work, where I support students’ social, emotional, and behavioral needs.

I specialize in play-based therapy and have extensive experience working with children with special needs. I also support individuals dealing with anxiety, depression, trauma, and family challenges. I strive to create a warm, supportive environment where clients feel safe, understood, and empowered. My goal is to help each client develop practical coping skills and build confidence in themselves both at home and in everyday life.

Reaching out is a courageous first step, and I would be honored to walk alongside you.

Hi, I’m Britta! As a Limited License Professional Counselor (LLPC)

Sarah Densham

Hi! I’m Sarah Densham (she/her), a limited licensed clinical therapist offering in‑person and virtual therapy for clients ages 5 and up.

I believe therapy works best when people feel genuinely seen and supported. I bring warmth, curiosity, and compassion to each session, creating a safe, collaborative space for healing. My approach is holistic and trauma‑informed, integrating somatic, mindfulness‑based, and evidence‑supported practices to help clients build self‑understanding, resilience, and meaningful change.

Originally from Ann Arbor, I studied Psychology and English at Kalamazoo College and later earned my MSW and Certificate in Trauma‑Informed Practice from the University of Michigan. I now call Grand Rapids home and enjoy the beach, yoga and barre, reading, and creative hobbies.

I have extensive experience working with children with autism, behavioral challenges, and emotional regulation needs. I use play therapy and strengths‑based, attachment‑focused, and neurodiversity‑affirming approaches to help children build coping skills and confidence.

I also support adolescents, young adults, and adults navigating anxiety, depression, ADHD, trauma, life transitions, and sports‑related stress. As a former collegiate diver, I bring personal insight and clinical training to my work with athletes, helping them enhance performance and well‑being both in and beyond sport.

Across all ages, I tailor treatment using Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), Internal Family Systems (IFS), somatic therapies, and mindfulness. Above all, I aim to help clients cultivate self‑compassion, resilience, and lasting growth. I would be honored to work with you or your child.
