Compassionate Care Meets Real Change
At City Psychology Group, we specialize in evidence-based care, tailored to the unique needs and goals of our clients. Our skilled psychologists help clients break out of unhealthy cycles they may be stuck in, and better understand the connection between their thoughts, emotions, and behaviors. We specialize in Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and mindfulness-based therapies. Our approach is practical, personalized, and effective, with in-person care in Manhattan and Westport, CT, and virtual sessions for clients who wish to be remote.

How We Can Help
Featured Treatment
Relationship Counseling
Featured
Relationships are at the heart of everything we do. Whether you’re navigating communication breakdowns, trust, or major life changes — our therapists are here.
Anxiety Therapy
Anxiety is one of the most common reasons people reach out to us — and one of the most treatable conditions we treat. Whether it’s constant worry, panic, or social anxiety, our psychologists use cognitive behavioral therapy (CBT) and Acceptance and Commitment Therapy (ACT) to help you feel like yourself again.
OCD Treatment
OCD can be exhausting — the intrusive thoughts, the rituals, the constant sense of being trapped in a loop. Our therapists use exposure and response prevention (ERP), the most effective evidence-based approach for OCD, to help you gently break that cycle and take your life back.
Depression Treatment
Depression is more than just feeling sad — it can make everything feel heavy, distant, and pointless. Our clinicians work with you, to help lift that weight, rebuild momentum, and learn skills to help build a life that feels meaningful to you.
Insomnia Treatment
Poor sleep affects everything — your mood, your focus, your relationships. CBT for insomnia (CBT-I) is more effective than sleep medication for most people, and the results actually last. We’ll guide you through a structured program to help you sleep properly again.
PTSD Therapy & Trauma Counseling
Trauma changes the way we see the world — and ourselves. Whether you’re dealing with a single event or years of accumulated experiences, our therapists offer trauma-focused CBT and prolonged exposure therapy in a space that’s safe, paced, and genuinely supportive.
Grief Counseling
Grief doesn’t follow a schedule, and it doesn’t always look the way we expect it to. Our grief counselors offer a quiet, unhurried space where you can feel whatever you feel — and slowly, when you’re ready, find your way through.
Child & Adolescent Therapy
Our child psychologists specialize in anxiety disorders, depression, ADHD and other conditions experienced during this stage of life — and we always make sure parents feel like part of the process, not an afterthought.
Perinatal Mental Health
Becoming a parent can be one of the greatest and most challenging life stages that people go through – and it’s okay if it’s harder than you expected. We support parents through prenatal anxiety, postpartum depression, and every emotional change in between with warmth and clinical expertise.
Relationship Counseling
Every relationship hits difficult patches. Our therapists use the Gottman Method and other evidence-based approaches to help couples and individuals work through communication breakdowns, trust issues, and life transitions — and come out the other side feeling closer.
Life Transitions
Big changes — a new job, a breakup, a move, a loss of identity — can knock you sideways even when they’re supposed to be positive. Our therapists use CBT and ACT to help you build the emotional tools to handle what life throws at you, whatever that looks like.
Who We Work With
Children & Adolescents
Our child psychologists support young people through anxiety, ADHD, and the big transitions of growing up.
Adults
Whether you’re dealing with anxiety, burnout, relationship difficulties, or just feeling stuck — we can help.
Older Adults
Warm, dedicated support for older adults navigating transitions, loss, and the changes that come with aging.
Couples
Relationship counseling and couples therapy for partners at any stage — working through conflict, trust, or reconnecting after a difficult period.
Meet the Cofounders
Dr. Sandy Krohn
PsyD, MA, Co-Founder and Executive Director
Dr. Krohn co-founded CPG because he believed people deserved care that’s effective, client centered, and genuinely human. He specializes in anxiety disorders, life transitions and couples work — using Cognitive Behavioral Therapy and Acceptance and Commitment Therapy, (ACT) and a collaborate style that is humanistic at its core.
“I think listening is probably the most important thing we do as psychologists, but we must always be focused on providing our patients with the skills and tools they need to feel better, faster.”
Dr. Amanda Volper
PsyD, MA, Co-Founder and Executive Director
Dr. Volper co-founded CPG out of a conviction that excellent clinical care and real warmth don’t have to be a trade-off. She specializes in trauma counseling, perinatal mental health, and couples therapy — bringing honesty and warmth to every session.
“In most group practices right now, patients are assigned randomly to who has space. We make sure to tailor the experience before assigning a patient.”
