"To find speech and occupational therapists who are amazing at what they do, are kind, energetic and genuinely care for your child's entire well-being is not an easy thing. Luckily for our family, we have found such speech and occupational therapists in Kim Gilsenan and Jamie Costa, respectively. We began with them when our son was 22 months and we are so blessed to have had their support on our journey. They have worked tirelessly with our son, helped to reveal his strengths and worked through challenges on all levels -- speech, fine/gross motor skills, play and social skills. They have been, and are his greatest advocates and we recommend them wholeheartedly without reservation."
"I refer to Gilsenan and Costa as my dream team! They have been
there for all three of my children. From handwriting, to speech
and to feeding issues, they have the knowledge and compassion
to help. They truly get my kids and their needs. I know because
I have seen positive changes in their development. Gilsenan and
Costa are not only therapists. They are true friends to
"Today, my daughter completed a tree top high-ropes course 60
feet off the ground all while chatting up the adults around
her giving them instructions on how to complete the challenges.
This is the same girl who three years ago was afraid of ceiling
fans, slouched and refused to speak. Thanks, Kim and Jamie
for everything you’ve done for her!"
"The therapists at Gilsenan and Costa have a remarkable ability
to craft programs that are simultaneously substantive and
stress-free. My son not only improves continuously, but also
looks forward to his sessions every week, both of which are
critically important to me."
