About Us
Sandi Stasko’s journey into counseling began with a deep desire to help others, though it took some time before she fully committed to the educational path required.
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.

Rachel Watson, LMSW
Practice Manager
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.
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.

Hope Tinholt
Hi! I’m Hope Tinholt, a part-time outpatient therapist at Key2Happiness.
I’ve been practicing social work for 3 years and recently joined Key2Happiness 6 months ago. I am committed to providing a safe, non-judgmental space to help you through your healing journey.
I have experience in working with children and teens who experience anxiety, trauma and a variety of other challenges. I received my undergraduate degree in Psychology at Grand Valley State University in 2018 and my Masters in Social Work from Grand Valley State University in 2021.
When I’m not practicing, I enjoy playing and watching a variety of sports while spending time with friends and family.
