Matthew Horton, LPC

As a Licensed Professional Counselor, I have experience collaborating with individuals, families, and groups of people who desire to make significant, lasting changes to their lives through therapeutic intervention. To date, I have provided services in psychiatric hospitals, residential treatment facilities, and directly in the homes of clients ranging from preschool age to those well past retirement.

I have aided my clients in processing an array of conflicts, including:

  • Parenting skills
  • Sexual trauma
  • Stress
  • Trauma
  • Anxiety
  • Behavior modification and management
  • Substance use
  • Grief and loss
  • Depression
  • Social and communication skills

Over the course of my career, I have been fortunate enough to receive training and supervision in the likes of psychoanalysis, CBT, TF-CBT, DBT, and Theraplay. I most strongly believe in the therapeutic alliance, which means that

I promise to spend time getting to know you and your unique strengths and needs, and identify any number of different interventions to provide you with the relief you deserve.


Susan Jillson, MSW, LISW-CP

I have always had a passion for serving others and decided to return to school after having children of my own, to pursue a Master’s in Social Work. I graduated from Fordham University and became a counselor in a residential program where I worked with clients who were struggling with a myriad of mental health issues such as depression, anxiety, PTSD and substance abuse. I provided both individual as well as group therapy and helped to carry on the Agency’s mission of reducing the barriers to treatment as well as de-stigmatizing mental health and addiction.

My approach to therapy is multi-faceted as I believe that each individual has their own unique story and therefore the course of treatment is individualized to meet the specific needs of my clients, keeping in mind of what stage of change they are in, their life stages and personal challenges. I utilize evidence-based modalities such as Dialectical Behavioral Therapy, Cognitive Behavioral Therapy and Motivational Interviewing.

I have experience helping with:

  • Anxiety
  • Depression
  • PTSD
  • Grief and loss
  • Substance abuse
  • Individual Therapy
  • Family Therapy
  • Self-esteem issues
  • Anger management
  • Stress management

I am passionate about my work and I am a strong advocate of educating my clients and their loved ones regarding the struggles with mental health and addiction issues and how these challenges may impact each other and their support systems. “Everyone deserves to be treated with dignity and respect and Our Stories help to weave and create our own unique and individual tapestries that should be shared, cherished and worn with pride.”
