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.

He believes everyone deserves a space where they can feel understood, supported, and accepted, especially during some of life’s most difficult seasons. His goal is to help clients feel less alone while discovering their strengths and finding meaningful ways to move forward.
Mason’s path toward becoming a therapist has been shaped by his experiences supporting children, families, and individuals through difficult moments. He has worked in residential treatment with children, supported individuals in crisis as a 988 Suicide & Crisis Lifeline specialist, and worked at the Taylor University Counseling Center.

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 rather than tell you who you should be or where you should go. Together, you’ll identify what matters most to you and work toward meaningful 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 without fear of judgment. With children and teens especially, he values creating an environment where therapy feels approachable, engaging, and connected to their world.
Mason hopes clients leave his office feeling heard, valued, supported, and reminded that they don’t have to navigate everything alone. He considers it an honor to walk alongside people during vulnerable moments and strives to meet each person with compassion, humility, and understanding.
Outside of therapy, Mason enjoys watching and playing sports, especially cheering on the Colts. He also enjoys golf, spending time with family and friends, focusing on his faith, and making the most of 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. We can take the next step together.

She believes everyone deserves a space where they can feel understood, supported, and free to be themselves. Her goal is to build genuine connection with each client while helping them better understand themselves, recognize their strengths, and navigate life’s challenges.
Lucy earned her bachelor’s degree in Psychology from Indiana University with a minor in Youth Development before completing her master’s degree in Clinical Mental Health Counseling at Ball State University. During her time as a peer tutor, Lucy discovered a particular passion for working with neurodivergent individuals and learning how to adapt her approach to each person’s unique needs. She also served as the Mental Health Chair for her sorority, strengthening her passion for creating supportive conversations around mental health.
Lucy especially enjoys working with children, teens, and young adults navigating anxiety, depression, ADHD, trauma, emotional regulation, self-esteem, life transitions, and relationship or family concerns.

At Talk Indy, Lucy is welcoming, laid-back, collaborative, supportive, nonjudgmental, and creative. She believes you are the expert on your own life, and her role is to come alongside you rather than tell you who you should be. Together, you’ll identify what matters most to you and find approaches that fit your personality, needs, and goals.
Lucy believes therapy doesn’t always have to look like sitting across from someone and talking. Especially with children and teens, she enjoys incorporating play, creativity, movement, and hands-on activities to help clients feel comfortable and express themselves in ways that come naturally to them. Her approach draws from CBT, DBT, ACT, Family Systems, Motivational Interviewing, Play Therapy, Solution-Focused Therapy, and mindfulness.
Most importantly, Lucy wants her clients to know they don’t have to go through things alone. You don’t have to have everything figured out before coming to therapy, and you don’t have to know exactly what you need. You can figure that out together. Lucy’s hope is that when clients leave her office, they feel heard, understood, supported, and reminded that they have someone in their corner.
Outside of therapy, Lucy enjoys spending time with family, going to the gym, creating art, discovering new coffee shops, and attending concerts at Ruoff. She loves spending time with her cat, Beans, and her dog, Toby, and she can often be found thrifting for unique jewelry and clothing.

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.
