About InParentis

Through our workshops, talks and coaching, we hope to make your
parenting less stressful, more fulfilling, and even more joyful

We know all parents want what’s best for their children, but at times it can be difficult to decide what “best” is. Our aim is to help you figure out what this means for you. We offer you concrete solutions that blend your goals and individual family needs with our expertise.

As psychologists* who are moms, we know first-hand how challenging and humbling parenting can be. As parent-child experts, we each have a background in development, psychology, family dynamics and parenting — a unique combination. With our lifespan perspective — gained from extensive work with children, adolescents and adults — we hope to help you anticipate the next steps in your family’s development to safeguard against potential difficulties in the future.

We are also dedicated to helping anyone in a role caring for children and adolescents: advising extended family members, teachers and caregivers. We are also available for public speaking engagements and to consult with schools and other child-related organizations.

She has practiced as an individual psychotherapist, family and group therapist, neuropsychological evaluator, and consultant to schools, organizations and fellow colleagues. Iris’s extensive experience working with preschoolers, school-age children, and their parents stems from her work in numerous programs, including the Barnard Toddler Center, Jewish Board of Family and Children’s Services, as Director of Early Childhood Staff and Education at the Pacella Parent Child Center, as well as several clinics and hospitals. She is a recognized expert on adolescents, young adults, and their parents, having served in many roles in several hospitals, clinics and schools, such as the Upper School Psychologist of Trinity School. She is an often sought-out speaker and advisor on topics related to tweens and teens.

Kristin Perry, PsyDKristin Perry, PsyD



Dr. Kristin Perry has spent nearly 30 years working with children, adolescents, parents, adults and couples. Much of her clinical experience has taken place in diverse settings including nursery, elementary, middle and high schools, and at area hospitals and clinics such as Stamford, Four Winds, and St. Luke’s-Roosevelt. Some examples of the kind of work Kristin has engaged in includes conducting parent-child and family therapy, running social-skills groups with children, support groups for young teens, as well as mother/infant and mother/toddler groups, administering neuropsychological assessments, and providing psychotherapy. Kristin’s frequent consultations to public, private and special needs schools have been ongoing for many years. Kristin is particularly distinguished for her work with special needs children and their families. As such, she was cited as a resource for parents in “A Parent’s Guide to Special Education in New York City and the Metropolitan Area” by Laurie Dubos and Jane Fromer.  Kristin devoted much study to the treatment of couples and has used this knowledge to create a unique hybrid model combining parent guidance and couples work.


Kristin earned her doctorate in School-Clinical Child Psychology from Pace University. After completing her internship, she was awarded a fellowship in the Department of Child Psychiatry at St. Luke’s-Roosevelt Hospital and subsequently joined St. Luke’s as a staff psychologist. Ongoing education is a significant priority for Kristin. She is informed in part by interpersonal neurobiology and attachment models and is learning about psychobiological stress resolution by becoming an SE practitioner through the Somatic Experiencing Trauma Institute.

Research and Teaching

Kristin has supervised psychology graduate students in adult and child psychotherapy at Pace University and at Columbia University’s Teacher’s College and served as an Adjunct Professor of Psychology at Pace University and Concordia College. Kristin participated in attachment-based seminars on infant research and adult treatment; in research on suicide prevention in adolescents, and conducted original research on the relationship between grandparents and their adolescent grandchildren’s academic achievement.

In Addition to InParentis…

Kristin is currently a board member of a district-wide schools foundation that provides funding for administrator, teacher and student programming. She has been in private practice for almost 20 years serving parents, children, adolescents, adults and couples and maintains a private practice in Manhattan and in Dobbs Ferry, NY.
