Get to know Brian
Brian Lahti, a Licensed Clinical Social Worker and the founder of Talk Indy, a private practice in Fishers and Carmel, Indiana. I started Talk Indy with the guiding belief: your voice matters.
My path to becoming a therapist has always been centered on creating spaces where people feel supported and understood. Early in my career, I worked in school environments, as a caseworker,and supporting children and families through some of their most difficult challenges. I later served as a therapist with an organization contracting with the Department of Child Services, where I walked alongside families navigating complex systems, trauma, and transitions. These experiences deepened my passion for helping children, parents, and individuals not only cope with challenges, but also build skills that lead to stronger, healthier connections.
At Talk Indy, I specialize in working with children, teens, adults, and families who are managing emotional and relationship trauma, ADHD, anxiety, depression, relationship stress, and life transitions. I also lead therapy groups that encourage creativity, emotional growth, and practical skill-building, because I believe healing happens best when we feel seen, heard, and connected. My approach blends compassion with creativity, often using engaging activities and tailored strategies to make therapy meaningful both in and outside of sessions.
I’ve always carried the heart of a servant in my work, and I continually strive to create a space for healing and growth. My goal is to empower clients while knowing they don’t have to navigate life’s challenges alone.
Outside the office, I’m a husband to my wife, Abby, and a dog dad to our golden retriever, Max. I enjoy exploring Indy’s food scene, supporting local businesses, and finding creative ways to blend play, connection, and healing in my work and daily life.
Cassie Trapp, MSW, LCSW
Get to know Cassie
Hi. My name is Cassie. If you are reading this right now, know that you are welcome here, and I am so glad you are taking the courageous step of reaching out for help today. It has been my life’s joy and work to walk alongside people of all ages who, for whatever reason, have found themselves in the trenches. In my career as a counselor, I have seen children heal from trauma, teenagers gain confidence through challenges, adults who feel hopeless find new meaning and purpose in their lives, hospice patients come to a place of peace as they approach the end of life, and everything else in between. No matter what you may be facing, it is my belief and experience that each of us has more capacity for hope, healing, and lasting change than we may yet realize.
I use a variety of trauma-informed and person-centered approaches that are completely tailored to you, your needs, and your goals. I long to facilitate healing from the past, help equip you to make positive changes for the present, and also to nurture a true, enduring hope for the future. I know that it is a sacred and vulnerable thing to be invited into the griefs, pains, traumas, and doubts of another. I will do whatever I can to make you feel comfortable, seen, and safe in our work together.
In my spare time, you will see me doing anything outside with my four kiddos or sending my wonderful children away so I can go on a date with my husband! I also love long walks with friends, reading books, watching Marvel movies, and traveling to new places.

Lily Snyder, B.S., Clinical Intern
Get to know Lily
Lily Snyder is a Bachelor of Science (B.S) Clinical Intern at Talk Indy who works with children, teens, families, and individuals navigating anxiety, depression, ADHD, trauma, relationship concerns, life transitions, stress, OCD, and other challenges that can make life feel overwhelming.
She believes therapy should be a safe, supportive space where clients feel heard, understood, and empowered to make meaningful changes.
Her passion for therapy is rooted in her own experience with anxiety. Growing up, Lily was extremely shy and fearful of new people, unfamiliar places, and new experiences. With the support of her family and healthcare providers, she learned how to manage her anxiety and gradually became the person she is today. That experience shaped her belief that everyone deserves access to the same understanding, compassion, and trust that helped her.
Throughout her professional experience, Lily has worked with individuals and families across a variety of settings, including inpatient and outpatient healthcare, the criminal justice system, children and families, and perinatal mental health. These experiences have taught her that there is no single “right” way to do therapy. Every person has a different story, different needs, and their own pace for healing.
Lily primarily uses cognitive-behavioral therapy (CBT), solution-focused therapy, and somatic approaches. Sessions may include goal-setting, cognitive restructuring, breathwork, body awareness, scaling questions, and psychoeducation. She takes a collaborative approach and believes the client is the expert in their own life. Together, she and her clients identify the tools and strategies that fit their individual needs.
Clients can expect therapy with Lily to feel laid-back, encouraging, educational, and collaborative. She strives to create an environment where clients can be honest about what they’re experiencing without judgment or pressure. Her hope is to help clients make sense of their past, build skills for navigating the present, and feel more confident about their future.
Lily believes that everyone is capable of healing when they have the right tools and a safe environment in which to use them. Her goal is to provide the kind of understanding, compassion, and trust that made such a difference in her own life while helping each client feel that their needs and experiences truly matter.
Outside of therapy, Lily loves reading, exploring local coffee shops, trying fun iced lattes, spending time in nature, and experiencing life with her partner, Aaron. She can often be found taking a walk, curled up on the couch with her Kindle and a blanket, or listening to folk and indie pop, especially Noah Kahan.
She wants you to know: You are the priority in this space, and you deserve time dedicated to your mental health, healing, and growth.

Mason DeHoff, B.S., LMHC-A
Get to know Mason
Mason is a Licensed Mental Health Counselor Associate (LMHC-A) serving children, teens, adolescents, adults, and families in Fishers, Indiana. He has always felt a deep desire to help and serve others and believes everyone has the ability to create a better tomorrow. He believes that every person deserves to experience mercy, grace, compassion, and genuine connection, especially during some of life’s most difficult seasons.
Mason’s path toward becoming a therapist has been shaped by his family, friends, mentors, and his love for Christ. Along the way, he has gained experience working in residential treatment with children, supporting individuals in crisis as a 988 Suicide & Crisis Lifeline specialist, and working at the Taylor University Counseling Center. These experiences have strengthened his passion for walking alongside children, teens, adults, and families navigating depression, anxiety, trauma, suicidal thoughts, and other challenges that can make life feel overwhelming.
At Talk Indy, you’ll find Mason to be collaborative, encouraging, laid-back, and honest. He believes you are the expert in your own life, and his role is to come alongside you, not tell you who you should be or where you should go. Together, you’ll identify what matters most to you and work toward meaningful, lasting change at a pace that feels right for you.
Mason draws from approaches including Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), Family Systems, Solution-Focused Therapy, Play Therapy, and mindfulness. He works to create a space where you can be honest about what you’re experiencing, feel accepted for where you are, and have the support and encouragement you need to take your next step.
Mason deeply believes that genuine human connection can be a powerful part of healing. He considers it an honor to be invited into people’s lives during vulnerable moments and strives to meet each person with grace, humility, compassion, and understanding. His hope is that when you leave his office, you feel heard, valued, supported, and reminded that you don’t have to navigate everything alone.
When Mason isn’t working, you’ll probably find him watching or playing sports, especially cheering on the Colts. He enjoys golf (even if he’ll be the first to admit he’s not very good at it), spending time with family and friends, and enjoying the moments that make life meaningful.
Most importantly, Mason wants you to know: You don’t have to have everything figured out before reaching out. I’m here for you, and I genuinely care about what you’re going through.

Get to know Ashtin
Ashtin is an Administrative Assistant at Talk Indy while pursuing her education in school counseling and working toward becoming a licensed mental health counselor. She is supportive, collaborative, and client-centered, and believes everyone deserves to feel comfortable, understood, and supported throughout their therapeutic journey. To Ashtin, therapy should be a welcoming space where you can work through challenges, better understand yourself, and discover strategies that work best for you.
Ashtin’s journey toward becoming a therapist began in high school, after experiencing challenges within her own family and having difficulty finding the right support. Those experiences inspired her to become the kind of person she wished she had during that time. Since then, she has developed a genuine passion for helping others heal and creating spaces where people feel safe, comfortable, and accepted.
At Talk Indy, Ashtin’s primary role is supporting our clinicians and helping create a positive experience for every person who walks through our doors.

If you have the opportunity to connect with Ashtin, you’ll be greeted by someone who genuinely wants your experience at Talk Indy to feel collaborative and focused on finding what works best for you.
Ashtin believes people are capable of meaningful change and growth when they feel supported, understood, and given the space to work through things at their own pace. Her goal is to support both you and your clinician in creating an experience that helps you move toward your goals while leaving you feeling heard, understood, and supported. She hopes every person who works with Talk Indy walks away with a greater understanding of themselves and a sense of hope about their next step.
When Ashtin isn’t working or studying, you’ll likely find her watching or playing basketball. She is a huge Notre Dame fan and loves attending football games with her family. She also spends much of her free time with her beloved Bernedoodle, Bentley.
Most importantly, Ashtin wants you to know that you don’t have to go through things alone. When you’re at Talk Indy, you can expect a welcoming environment without judgment and a team that genuinely cares about helping you feel supported along the way.
