Joseph R. Kiefer, PT                                                                                                                                                                                                              Physical Therapist/Founder/Owner

I have been in practice since receiving a Masters Degree in Physical Therapy from Hahnemann University in 1994. My work has focused on motor learning and motor development in children. I feel privileged to have published articles in the Pediatric Physical Therapy Journal regarding fetal alcohol syndrome and cerebral palsy. I completed my Internship at Georgetown University Child Development Center and worked as a senior pediatric therapist at United Cerebral Palsy before starting my own practice in Westchester. The drive behind opening a pediatric center is seeing how motivated the kids get when receiving “therapy” in places other than their homes, one they view as fun places. Developmental Steps is that “Fun” Place. I love helping kids find a way to “Do” something through a strategy, practice, or making it plain old fun. Playing with my 2 kids, going on bike rides or hikes with my wife and 2 dogs, skiing in Vermont and going to Montauk is how I fill my free time when not at home in Katonah, NY.

I have been practicing as a Physical Therapist since receiving my Masters Degree in Physical Therapy in 2003 and Doctorate of Physical Therapy in 2006 from Boston University. Having been a competitive gymnast has left me with a love for fitness..  Being at Developmental Steps, LLC since 2008, I have extensive experience with multiple diagnoses but not limited to torticollis, hypotonia, cerebral palsy, neurological injuries, and developmental delay.  I’m enthusiastic about children and pride myself on being able to make a difference in the lives of patients and their families through using manual techniques, while making it fun at the same time.  I also love teaching community tummy time classes for new parents.  I live in Katonah with my husband and 2 children.

I joined the Developmental Steps Team as a Physical Therapist in April 2019. After earning my Doctorate in Physical Therapy from New York Medical College, I continued to practice as a Physical Therapist in Outpatient Orthopedics for almost ten years.  After meeting Hayley at Stroller Strides, and then bringing my son into Developmental Steps for treatment, my passion to practice in a pediatric setting was reborn. I was further inspired watching the team at Developmental Steps work together cohesively and efficiently while taking extra special care of their patients. I love working with infants and children; especially having the ability to design fun and creative activities. I find it most rewarding to see the pride and joy they have when they achieve a new skill. I currently live in Elmsford, NY with my husband and three children.

I joined the Developmental Steps Team as a Physical Therapy Assistant in July 2019 after earning my degree at Norwalk Community College. Prior to that I received my Bachelors in Athletic Training at Sacred Heart University. Having 5 years of experience as an Athletic Trainer working with HS athletes, as well as treating outpatient pediatric and orthopedic patients has been a fulfilling experience. Since working at Developmental Steps, I have become more passionate and excited as I am able to provide a fun, warm and creative environment for the children. I love to see a child “light up” as they achieve a new skill and become the best they can be! I enjoy time spent with family & friends and teaching my young cousins how to play sports.  I stay active by attending kickboxing & yoga classes, running, hiking and playing soccer. I currently live in White Plains, NY.

I received my Associates Degree as a Physical Therapist Assistant and Massage Therapist in 2001. Having over 5 years of experience as a Physical Therapist Assistant working with a variety of patients has prepared me for a future that includes pediatrics, athletics, post surgery rehab, and geriatrics. I have also had extensive experience as a massage therapist, personal trainer, and fitness instructor. I joined Developmental Steps, LLC in the spring of 2020 and I am currently treating in the schools, doing backyard training sessions and camps, and treating patients in our offices. I love working at Developmental Steps, the pediatric field is so rewarding and I enjoy the playful nature of interacting with children and the creativity and joy that ensues. Health and fitness have always been an important part of my life.  I strongly believe that early childhood physical therapy can unlock a lifetime of good health. I live in Katonah, NY with my husband and three extremely active children involved in multiple sports.

I joined the Developmental Steps Team as a Physical Therapist in September 2021 after earning my Doctorate in Physical Therapy from Northeastern University in Boston, MA. Prior to that, I received a Bachelor’s degree in Exercise Science with a minor in Biology from SUNY Cortland and was a student athlete on the softball team. During my time at Northeastern University, I worked with children with severe disabilities and/or deaf/blindness at Perkins School for the Blind, volunteered in an adaptive soccer program for children with Autism and Down Syndrome, and traveled to Ecuador to provide physical therapy services for children with disabilities in a school setting and an orphanage. These experiences fueled my passion to pursue a career in pediatric  physical therapy. I love being able to develop relationships with children, help them achieve their goals, and make a positive impact on their lives! I enjoy spending time with family and friends, playing with my dog Bella, engaging in outdoor activities such as hiking, bike riding, and playing sports. I currently live in Mahopac, NY.

I received my Doctorate in Physical Therapy from Northeastern University in May 2020. After being raised and attending college in Massachusetts, I moved to White Plains, New York in August of 2020 to pursue a pediatric career. As a former gymnast, I fell in love with the field of physical therapy early on as a patient myself. Between being an overnight camp counselor, Special Olympics gymnastics coach, and interning at a school for children with disabilities, I quickly learned that my true passion was pediatrics.  I love helping children reach their full potential and gain skills that they will use for the rest of their lives. When I am not at Developmental Steps, you can usually find me coaching gymnastics, on a run, eating ice cream, or curled up with a good book!

I have been a part of the Developmental Steps family since 2014. With me came 20 years of experience working with children in a nursery school and in pediatric medical offices. Always loving the interaction with people, I greet patients, schedule appointments, handle telephone correspondence, maintain medical records and financial accounts as well as assist families with insurance issues. It brings me great joy to see a child meet their goal and find that they have the power within themselves to become stronger and be able to be proud of their accomplishments!. My love of children and passion for their health and wellbeing makes me feel like a perfect addition to the Developmental Steps team! My husband and I currently live in Ardsley, NY and love spending time with our 2 daughters and families.

I discovered and joined Developmental Steps in 2018. I have a Bachelor’s Degree in Communication Arts and have many years of experience with marketing and public relations for different types of companies. Loving the interaction with our patients and their families, as well as helping them feel comfortable before their physical therapy appointment is important to me. I am truly happy to watch the children get stronger and faster right before my eyes. I also enjoy working with the therapists on developing creative ideas to share and show how unique the Developmental Steps family really is!  At home in Goldens Bridge, my husband, three kids, and our silly dog all enjoy an active lifestyle with hiking and year round sports.

Seeing children make positive improvements through hard work and dedication drives me to be in this profession. I have grown up in the Westchester area my entire life and am a proud dog mom!
