Dr. Gabriella Nissan
Dr. Gabriella Nissan earned her Bachelor of Arts in Psychology from Barnard College at Columbia University. She graduated from Hofstra University with a Master of Science and a Doctor of Psychology (Psy.D.), both in School-Community Psychology. Her clinical training was completed across a variety of settings, including community clinics, schools, and psychiatric hospitals.
Dr. Nissan's clinical externship training took place at Jamaica Hospital Medical Center, where she provided treatment to a diverse population of patients experiencing serious mental illness in both in-patient and out-patient settings. She completed a postdoctoral fellowship at Blue Anchor Psychology, a private practice in New York City, where she received specialized training in couples therapy and sex therapy. She then continued working at the group practice for several years before opening her own private practice.

Individual Therapy in New York City
Individual therapy provides a supportive, confidential space to better understand your thoughts, emotions, relationships, and patterns of behavior. At New Leaf Psychology, I tailor therapy to each client's needs, goals, and life experiences, with a focus on helping you create meaningful and lasting change.
Therapy can be helpful when you're experiencing anxiety, persistent stress, low mood, relationship difficulties, or navigating a major life transition. You may be struggling with excessive worry, overthinking, intrusive thoughts, low motivation, emotional disconnection, or simply feeling stuck and unsure of how to move forward.
As a clinical psychologist, I use evidence-based psychotherapy approaches to help clients develop practical tools while also exploring the deeper patterns that may be contributing to current challenges. Treatment may incorporate Cognitive Behavioral Therapy (CBT) to identify and change unhelpful patterns of thinking and behavior, as well as Acceptance and Commitment Therapy (ACT) to build psychological flexibility, strengthen coping skills, and support actions that align with your values.
Whether you're seeking support for a specific concern or hoping to develop greater clarity, confidence, and emotional well-being, individual therapy offers a collaborative path toward growth and resilience. I offer in-person therapy in Midtown Manhattan and online therapy for clients located in New York, New Jersey, Pennsylvania, and eligible PSYPACT states.
Couples Therapy in NYC
Couples therapy can help partners strengthen communication, better understand recurring patterns, and work through challenges that may be affecting trust, intimacy, and emotional connection. At New Leaf Psychology, I provide a supportive and collaborative space where couples can address concerns openly and develop healthier ways of relating to one another.
I incorporate the Gottman Method Couples Therapy, an evidence-based approach that helps couples improve communication, manage conflict more effectively, rebuild trust, and deepen friendship and connection. Treatment focuses on practical skills that couples can use both during sessions and in their everyday lives.
Couples may seek therapy for frequent arguments, communication breakdowns, emotional distance, intimacy concerns, infidelity, major life transitions, or difficulty resolving long-standing conflicts. Therapy can also be valuable for couples who are not in crisis but want to strengthen their relationship, improve their understanding of one another, and build a more fulfilling partnership.
Whether you are navigating a specific relationship challenge or simply hoping to grow closer, couples therapy offers structured guidance, practical tools, and a collaborative path toward greater connection and mutual understanding. I offer couples therapy in Midtown Manhattan and online for couples located in New York, New Jersey, Pennsylvania, and eligible PSYPACT states.

Evidence-Based Therapy Tailored to You
At New Leaf Psychology, therapy is personalized to your individual needs, goals, and experiences. I use evidence-based approaches while adapting treatment to what is most helpful for each client.
Depending on your concerns and goals, therapy may incorporate Cognitive Behavioral Therapy (CBT) to identify and change unhelpful patterns of thinking and behavior, or Acceptance and Commitment Therapy (ACT) to build psychological flexibility, strengthen coping skills, and support choices that align with your values.
For couples, I may incorporate Gottman Method Couples Therapy to improve communication, manage conflict, rebuild trust, and strengthen emotional connection. For clients experiencing chronic pain, Pain Reprocessing Therapy (PRT) may help address the ways the brain and nervous system can contribute to persistent pain.
Treatment may also draw from other therapeutic strategies based on your specific needs, whether you are seeking support for anxiety, depression, relationship difficulties, intimacy concerns, chronic pain, or major life transitions.
The goal is not a one-size-fits-all approach, but a thoughtful, collaborative treatment plan designed to help you better understand yourself, develop practical skills, and create meaningful, lasting change.
Cognitive Behavioral Therapy (CBT)
A goals-oriented approach focusing on how your thoughts, beliefs, and attitudes affect your feelings and behavior. Together, we identify and change negative patterns to improve your daily functioning.
