I’m Jack Haines, a licensed marriage and family therapist in New York. I work with individuals and couples navigating relationships, anxiety, life transitions, and questions around identity or sexuality.

My approach is warm and collaborative. Together, we can understand patterns that keep repeating and explore new ways forward.

Therapeutic Approach

Jack believes lasting change comes from combining insight with practical action. His work is collaborative: clients bring knowledge of their lives, while he offers curiosity, clinical experience, and tools tailored to their goals.

  • Emotionally Focused Therapy (EFT): Exploring the emotions beneath conflict and helping individuals and couples build greater safety and connection.

  • Cognitive Behavioral Therapy (CBT): Noticing beliefs and habits that affect feelings and behavior, then practicing more helpful responses.

  • Mindfulness: Paying attention to thoughts, feelings, and reactions with more awareness and less automatic judgment.

  • Family Systems and IFS-informed work: Understanding the different parts of ourselves and the relationship patterns that shape how we respond.

  • Gottman Method: Using practical tools to strengthen communication, friendship, and conflict management between partners.

  • Psychodynamic and strength-based work: Considering the influence of earlier experiences while building on strengths clients already have.

Ketamine-Assisted Psychotherapy (KAP)

Ketamine-assisted psychotherapy brings therapeutic support into a course of ketamine treatment. Some people find that the experience opens a different perspective on emotions or familiar patterns. Psychotherapy offers space to explore what arises and connect it to the concerns that brought them to treatment.

Preparation can involve clarifying intentions, discussing hopes and concerns, and identifying sources of support. Integration takes place after a ketamine experience: clients reflect on what felt meaningful and consider how to carry those insights into everyday life and relationships.

Jack approaches this work with curiosity, care, and attention to each client’s goals. Ketamine is not appropriate for everyone; a qualified medical provider is responsible for determining medical suitability, prescribing, and monitoring treatment.

LGBTQ+ Care

LGBTQ+ affirming therapy is central to Jack’s practice. Clients may come to explore identity or sexuality, work on a relationship, or address something else entirely. His sex-positive approach welcomes diverse relationship structures, including consensual non-monogamy and polyamory, as well as conversations about kink.
