Kathy Tsatsanis, PhD

You don’t have to do this alone.

I offer therapy and assessment services to my clients. I have expertise in psychological and neuropsychological assessment of children, adolescents, and young adults, and offer therapy to parents,  children, and adolescents. Though the things that may trigger anxiety, overwhelm, and despair vary from childhood through adulthood, I am interested in supporting individuals manage these painful experiences across the lifespan.

Who I work with


As a parent, you may find that you need a sounding board, someone outside your friends and family to listen and gain a bird’s-eye view. Or you may sense that you are getting stuck in a cycle of feelings, behaviors, and actions that are hard to make sense of or break out of, as you’ve attempted to adjust to a family member’s anxiety or depression or exceptional needs. Together, we will talk to gain an understanding of your situation and of feelings being held inside while gradually moving toward trying new approaches in order for change to occur.

Children & Adolescents

For tweens, teens, or young adults, finding yourself feeling overwhelmed, it can be challenging to access that inner voice and hear what it is saying with compassion versus self-judgment, especially in these demanding times. I hope to build a trusting relationship with you, to understand better what you are thinking and feeling, and gain an understanding of your experience. Together, we can look at strategies that help vary patterns of automatic thoughts, feelings, and actions.

My goal is to provide support, to listen, and to offer guidance where needed. Therapy is at its most effective when it is a collaborative relationship.


I provide comprehensive psychological/neuropsychological evaluations for young children, adolescents, and young adults. Processes measured may include: cognition; attention, memory and learning; executive functioning; academic skills (reading, writing, mathematics), and/or social emotional functioning. Information is gathered from multiple sources in order to provide a better understanding of your child’s learning profile and/or to assist in diagnostic clarification as well as recommendations.

My Background

I grew up in Toronto, Canada and graduated summa cum laude from the University of Toronto, majoring in Philosophy and Psychology. I subsequently earned my M.A. and Ph.D. in the Clinical Neuropsychology program at the University of Windsor. I came to Connecticut in 1995 to complete my pre- and post-doctoral clinical internship at the Yale Child Study Center (YCSC). I have been a faculty member at YCSC in various capacities since 2001, with periodic concurrent positions in Boston (Harvard Medical School/MGH) and, most recently, Naples, Florida (clinical practice). In addition to roles in research, clinical supervision, and clinical work, I served as Clinical Director of the Developmental Disabilities Clinic at YCSC from 2006-2010. I have taken great pleasure in each of these pursuits and now enjoy the privilege of building relationships with children and families through private practice in Guilford, CT.
