About Us

At Columbus Park we’ve assembled a team of experts, exclusively focused on treating eating disorders and their co-occurring conditions such as depression and anxiety. Working with clients of all ages – adults, adolescents, and children – our active, skilled and engaging therapists deliver the best evidence-based treatments available.

Columbus Park clinicians are recruited through a deliberate and thorough vetting process.  Most therapists come to us with intensive training and experience in behavioral therapies.  Once part of the Columbus Park team, the providers are given further specialized training in the leading eating disorder treatments and benefit from ongoing intensive professional development and consultation. The result is a team of the most talented, impeccably trained and well supported clinicians in the field.

Melissa Gerson, LCSW

Clinical Director & Founder

I started Columbus Park, the first private eating disorder day-treatment program in NYC, in 2008. Since then, Columbus Park has evolved into the leading outpatient eating disorder treatment center with a robust national reputation, delivering evidence-based treatment with the highest level of skill and exceptional outcomes.

I’m a native New Yorker who transplanted to Miami, Florida at 18 to dance with the Miami City Ballet. This background set the stage for my very personal understanding of the challenges of having to control one’s body shape and size to meet an impossible aesthetic – and sparked my interest in eating disorders. After seven years, touring with the MCB company, I retired from ballet and received a Psychology degree from Columbia University. I went on to earn a master’s degree in social work at New York University. In private practice, I developed more and more of an interest and expertise in disordered eating. I benefited from years of individual case consultation and supervision, working with experts like Judith Brisman, PhD, Julie Goldfein, PhD, Lucene Wisniewksi, PhD and faculty from the NY State Psychiatric Institute. I completed the two-year post-graduate training program in psychodynamic psychotherapy at NYU’s Psychoanalytic Institute. I also completed trainings in ED-specific treatment at the Center for the Study of Anorexia and Bulimia, NYC and the Eating Disorders, Compulsions and Addictions program at the William Alanson White Institute of Psychiatry, Psychoanalysis & Psychology.

Among my proudest achievements, I became a Certified Family-Based Treatment Therapist, after completing advanced training and extensive consultation in Family-Based Treatment (“Maudsley) through the Training Institute for Child and Adolescent Eating Disorders. FBT is the gold-standard treatment for childhood and adolescent eating disorders like anorexia and bulimia; I am thrilled to be able to support families so effectively in beating these potentially devastating illnesses.

This year, I launched my3square virtual meal support which is a video meal coaching platform for adult eating disorder patients anywhere in the country. I conceived of my3square as a far-reaching and affordable service that breaks down the barriers for people to gain access to quality eating disorder care.

In Columbus Park and with my3square, I’ve created a true center of excellence, with a robust team of skilled and engaging clinicians. I’m grateful for the impact we’ve had on so many lives thus far… and look forward to continuing to make a powerful mark in the field for many years to come.

Madelyn Bart, LCSW

Clinical Supervisor and Therapist

I received my BA with honors in psychology from George Washington University before graduating from Columbia University with my master’s degree in social work. I completed both the Intensive and Advanced Intensive Dialectical Behavior Therapy (DBT) trainings, facilitated by Behavioral Tech trainers, as part of Columbia University’s year-long DBT training lab. Prior to joining Columbus Park, I received clinical training as an intern at St Luke’s Roosevelt Hospital’s Child and Family Institute, where I provided outpatient treatment to children, adolescents and their families utilizing both Cognitive Behavioral Therapy (CBT) and DBT. I also worked as a primary therapist at The Jewish Board of Family and Children’s Services, providing trauma-focused therapy to adolescents, young adults and their families in a residential setting. In addition to training and practice in DBT, standard CBT and trauma-focused therapy, I received comprehensive training and extensive supervision in Enhanced CBT (CBT-E), the modality of choice for most eating disorders. Since early 2017, I have benefited from regular individual and group consultation from Lucene Wisniewski, PhD, an international eating disorder treatment leader and DBT expert, who has helped me enhance and refine my skills as an eating disorder and DBT clinician.  To further my expertise as an advanced DBT practitioner, I completed intensive training in the DBT Prolonged Exposure Protocol by Dr. Melanie Harned and Dr. Lori Ritschel. DBT PE has been found to be highly effective at treating PTSD.  As a Clinical Supervisor at Columbus Park, I train and oversee new clinicians as they enter the practice.  In my role as Primary Therapist, I conduct individual and family sessions along with supported meals and weekly DBT Skills Groups. In all of these settings, I deliver evidence-based treatments with my personal therapeutic style of curiosity, compassion and warmth.
