Professional statement

Keilyn Castillo is a Licensed Mental Health Counselor in Westchester, NY who specializes in anxiety, social anxiety, relationship issues, and depression. Her practice is open to both individuals and couples.

Keilyn's approach to treatment is integrative, and she tailors her therapeutic interventions to each individual client's presenting circumstances and needs. She is able to draw, as relevant to treatment, from diverse schools of thought like Cognitive Behavioral Therapy (CBT), Psychoanalytic, Existential, and Attachment Theory. Keilyn also encourages clients to embrace the present through the lens of mindfulness, which can soothe the overwhelm that often accompanies everyday stressors. 

When working with couples, Keilyn typically starts with an intake assessment to gauge where they are at both individually and as a unit. She often helps couples navigate communication issues, which may be at the root of other presenting issues. She also helps couples who are grappling with differences in parenting styles, intimacy concerns, and major life transitions. 

Keilyn’s warm, calming presence creates a safe space where clients are able to relax and make genuine progress, both in the therapy setting and their daily lives. She looks forward to working with you.

Message to clients

When's the last time you really felt heard? That someone was truly listening to you and what you had to say, instead of just waiting for their turn to speak? 

In these times when social media seemingly offers connections to anyone, yet can still leave you feeling unheard, unseen and disconnected from everyone, having someone give you their undivided attention and consideration can be a rare find. I am that rare find.
