Caitlin Karosen, LCSW

Hi, I’m Caitlin! I’m a licensed clinical social worker. I really enjoy a wide range of clients but particularly connect with those who, at their core, suspect they might feel things more deeply; those who feel “other”, between worlds, and chronically misunderstood. Through the co-creation of a safe, secure and authentic relationship, I work to help heal old attachment wounds and to harness your untapped, innate resources of resilience and growth. My clients report feeling more open, authentic and connected in their interpersonal relationships as a result of therapy. They also report feeling a greater ability to take charge of their lives.

Amanda Mayberry, LCSW

Hello, I’m Amanda! I am a Licensed Clinical Social Worker and Registered Play Therapist. I welcome all kids ages 2-10 to come and work on processing feelings, coping skills, self esteem, communication, social skills, anxieties or feelings of depression, and more in our play therapy room. When little kids have big feelings they need a safe place to process and explore. Play is the language of children and is how they communicate. It opens doors for them to understand themselves and the world around them. I can help facilitate this process utilizing a cognitive behavioral play therapy approach. I provide a safe, calm, empathetic space for children. Together we will collaborate to get your little one back on track and ensure your family is supported every step of the way.

Dr. Kendahl Shortway

Hi, I’m Dr. Shortway and am a Licensed Clinical Psychologist. My ideal client is someone who is curious about change and willing to engage in the process of therapy. I approach each client with appreciation and compassion for their past, current situation, and their hopes for the future. I try to meet clients where they are, and acknowledge that change and healing are often gradual and full of fluctuations. I consider myself a partner in those journeys for the time we work together in therapy, and I aim to empower clients to believe in themselves and their abilities to continue those journeys after our relationship ends. I utilize a variety of evidence-based treatments, primarily acceptance and commitment therapy and other cognitive behavioral therapies, and I consider social environments and current events as influences of distress. Ultimately, my priority is to maintain a kind, caring, and nonjudgmental stance towards clients and our relationship.
