About Haylee Kasallis (She/Her)

Haylee Kasallis, M.S., LPC Associate

Haylee Kasallis, LPC Associate, serves clients throughout Texas with a warm and empathetic approach, providing a safe space where individuals can explore life transitions, grief, and women’s issues. Haylee is dedicated to helping clients who feel they’ve managed life’s challenges independently but now seek clarity and guidance to navigate periods of uncertainty. She supports her clients in slowing down, reconnecting with themselves, and finding meaningful, sustainable shifts for personal growth and healing. With a passion for addressing women’s issues and codependency, Haylee empowers clients to uncover what lies beneath the surface, gently guiding them through their struggles with deep empathy and practical solutions. Her approach emphasizes self-compassion and internal validation, helping clients resist the urge for quick fixes and instead embrace a pace that fosters true transformation. Haylee’s focus on these areas allows her to help clients find resilience and independence in a way that feels authentic and empowering. Haylee provides individual therapy and couples therapy to adults of all ages, specializing in treating concerns such as depression, PTSD and trauma, and grief. She utilizes a blend of Cognitive Behavioral Therapy (CBT), grief counseling, and person-centered techniques to support her clients’ unique needs. Her inclusive practice welcomes clients of all genders, including those within the LGBTQ+ community, creating a compassionate and non-judgmental environment for all.

Outside of her work, Haylee enjoys recharging in nature by going on walks with her dogs, collecting Funko Pop characters to bring a bit of joy to her space, and finding new shows on Netflix to unwind. A dedicated reader of psychological thrillers and mental health research, she stays inspired in her practice and committed to supporting her clients. Haylee is honored to serve the Texas community, helping clients find clarity and confidence as they move forward on their paths to healing.

I see a great counselor. I feel like I’m finally benefiting from therapy. She is great and takes the time to listen to me, doesn’t make me feel rushed. Tries to relate to me to the best of her ability.
