What a blessed place for special needs children to learn and grow
This facility and it’s employees have been crucial to the success of our son. There are no words that can fully express my gratitude and appreciation for the help and guidance that we have received.
I can hardly express my gratitude to Trellis for all they have done for my son. My son was completely non verbal when he started Trellis and after a year of ABA, Speech and OT he has become much more independent and can now not only communicate verbally, he doesn’t even use his device any more, he is answering more complex questions that are far beyond “yes” and “no”. All of the instructors there are very helpful and patient. The management really takes an interest in finding the right fit for your child when it comes to selecting an instructor. I could not be happier with Trellis.
