About US

Our Philosophy

We always believe in taking a collaborative and introspective approach when working with adults, couples, families, or children. We believe this kind of approach to treatment helps patients have a deeper sense of their own wisdom and healing potential.

Because of deep emotional pain, wounds, and burdens that we each carry on a daily basis, we can often become disillusioned with ourselves or others. For most of us, our natural way of coping with these struggles is by avoiding or turning away from it. But despite the temporary relief it brings, this style of coping often maintains extreme beliefs, negative feelings, and unproductive behaviors.

We also believe that the relationship between the therapist and the patient is vital to any effective treatment.

By providing a safe, supportive, connected, and compassionate environment, people can find the strength to personally explore their struggles without being pushed, pathologized, or retraumatized. That is mainly why we empower and support our patients to turn towards these areas of difficulty and explore them in a manner that often leads to lasting change and new ways of relating to themselves, others and the larger world.

Robyn Bellinson, LCSW

Parent Workshop Series: Social Self Awareness

I am a Licensed Clinical Social Worker with over 20 years experience as a psychotherapist, helping families through difficult times in their lives. My interest in human development, from early childhood through adulthood, led me to pursue post masters advanced training from psychotherapy institutes in New York City and Westchester County.

More about Robyn

I started my private practice in Union Square, NY where I worked with many college students on reducing stress, forming new relationships, adjusting to living independently and establishing their identities. Upon moving my practice to Westchester county, I developed a strong focus on child, adolescent and family therapy. In collaboration with parents, we develop a more complex understanding of their child?s emotional needs. I see many families who are overwhelmed when their children are struggling. Together, we find new strategies for each developmental stage, and help children learn to regulate their emotions.

In addition, I often hear children express that they feel more understood and accepted in their home life. This greater sense of security and connection in their relationships, allows children the ability to be more confident in academics, peer relationships and pursuing areas of interest.

Robyn Bellinson has a BA in Liberal Arts from the University of Maryland. Masters Degree in Social Work from Adelphi University. Post Masters Training at Ackerman Family Therapy Institute. Adult Psychotherapy Training at New York School for Psychoanalytic Psychotherapy. Child Psychotherapy Training at Westchester Center for the Study of Psychoanalysis and Psychotherapy.

Amanda Schwartz, Ph.D.

I am a licensed psychologist who sees private practice patients in Mt. Kisco, NY. I believe in the power of a strong therapeutic partnership in supporting personal growth. I strive to provide a warm, non-judgmental, and safe space, where you can understand and work through your emotions and the stressors that you face in your life.

More about Dr. Schwartz

While therapy can be hard work, I aim to work collaboratively with you, to respectfully challenge you, and to assist you on a path toward personal growth and positive change. In therapy, I also integrate mindfulness practice, and utilize a cognitive behavioral (CBT) approach with a focus on relationship building, skill instruction, and goal-directed behavioral change.

For the past seven years, I worked as a school psychologist in an alternative therapeutic high school. In this role, I supported adolescents with significant anxiety, mood disorders, and learning and social challenges. I also enjoy working with parents as they navigate the challenges of parenting. When working with children or adolescents, I regularly involve parents in the therapy process, providing parent training and support as needed. I have extensive experience collaborating with other professionals to address children?s and adolescent?s emotional and learning issues.

I have also pursued training in perinatal mental health through Postpartum Support International, and I am passionate about supporting women on the often-challenging journey of transitioning to motherhood.

I graduated with Highest Honors from Emory University with a Bachelor of Arts in Psychology. I then went on to Fordham University, where I received my master?s degree (M.S.E.) in Therapeutic Interventions, and my doctorate degree (Ph.D.) in School Psychology.

Mark Hrastar, LMHC

I am a licensed psychotherapist with over a decade of clinical experience in a variety of settings. Much of my work involves treatment of depression and anxiety related to life changes and interpersonal relationships issues. My approach is supported by a background in psychodynamic theory and training in Motivational Interviewing, Mindfulness Based Cognitive Behavioral Therapy and Acceptance and Commitment Therapy (ACT). I draw on these select and various techniques to provide individualized and personalized treatment to my clients.

The goal of psychotherapy is to help facilitate change by developing awareness, compassion, acceptance and empathy toward yourself and others by identifying the values you want to define yourself by and to live by. My approach is the product of over a decade of experience working collaboratively with clients in an environment of non-judgement. I believe in taking an introspective and collaborative approach when working with adults and adolescents. I believe this allows the patient to develop the self-awareness needed to recognize their own ability to heal based on their own experiences and judgement.

My education includes a Masters of Arts and a Masters of Education in clinical and counseling psychology from Columbia University.
