PARENT TESTIMONIALS

The Aguilar Family

“ABA has truly transformed my son’s life. When we started this journey, I felt lost and unsure of how to help him manage his ASD behaviors—but then we met Maria Preston. From day one, she has been caring, patient, and deeply committed to helping my son reach his potential. She not only paired him with an incredible RBT who connects with him beautifully, but she’s also been a true advocate—for both my child and for us as parents. Maria’s passion, knowledge, and genuine love for what she does have made all the difference. Because of her, my son is thriving, happier, and more confident than ever. We will always be grateful for her dedication and the positive impact she’s had on our family.”

Carol Buckley

"I wanted to take a moment to express my deepest gratitude for all the support, care and dedication Maria Preston has shown our daughter. Since beginning ABA therapy at the age of four we’ve seen changes that go far beyond what we imagine impossible not just in behavior, but in confidence, connection and happiness. The small victories from making eye contact to initiating play were some of our biggest joys. Maria had shown professionalism with genuine care made such a difference. I strongly support and recommend the continuation of ABA therapy. It has truly changed my daughter‘s life, but our entire family dynamic for the better. Our daughter is now a college graduate in psychology and is now working with children with disabilities just like her mentor, Maria Preston. Thank you, Maria, for your endless patience, your heart, and your belief in our daughter’s potential. Your work is making a lifelong impact for so many families and we are so grateful to have had you in this journey and her/our lives."

Mary Alvarez

With over 25 years of experience in the field, she goes above and beyond for every child in her care. She advocates tirelessly for families to ensure each child receives the services and support they need to thrive. It is with the deepest respect and gratitude that I recommend Mrs. Maria Preston. She is an extraordinary BCBA, a gifted educator, and a true advocate for children with special needs. Her impact on our son and our family has been profound, and we will be forever thankful for her commitment and care."
