Hi there, I'm Cassandra!

"Hi, welcome. I'm glad you're here. My practice is a space for honest conversations, whether you're working through trauma, a rough patch as a couple, parenting struggles, depression, or a big life transition. Wherever you're starting from, you deserve support that feels genuine and steady."

My focus

"I work with individuals, couples, and families navigating trauma, depression, and major life transitions, including adolescents and young adults finding their footing, as well as parents managing the everyday challenges of raising a family. If you're feeling stuck or overwhelmed, I can help you find clarity and lasting change."

My approach

"I draw from CBT, DBT, trauma-focused, and psychodynamic approaches, along with the Gottman Method for couples and solution-focused techniques when practical progress is the goal. My style is reflective and collaborative. I tailor each session to you, blending structure and insight so therapy feels relevant, not one-size-fits-all."
