Developmental Steps, LLC is a Pediatric Physical Therapy Center owned and managed by licensed physical therapist Joe Kiefer and Hayley Apiscopa. Developmental Steps has TWO locations in Westchester County where we service clients in Port Chester and in Mount Kisco, NY!

If your child is challenged by any developmental or physical issues, or needs sports specific strengthening and training we can help! We offer a broad variety of pediatric therapy solutions to get your child the assistance they need. Our highly trained staff offers compassion to both you and your child during the time you will spend with us.

We treat every child receiving pediatric therapy with us as if they were our own children.

If your child has not qualified for Early Intervention(EI) or CPSE (3-5 year old services) or you just want to supplement these services or are waiting for an EI provider, we can help.

We provide services to:

Grade Schoolers

Your child will have the best care around while striving to reach their highest potential. We will make it fun for them while they achieve the growth you expect!
