Amanda Harpst SLP

Amanda Harpst / Aspire for Autism

Speech Pathologist

Amanda is the founder of Aspire for Autism. Amanda is a mother of three and speech pathologist. She graduated from Cal Poly with a BA in English and from Cal State Northridge, with a Masters in Speech Language Pathology. She has years of experience with children of all ages, starting with tutoring in her younger years, to her more recent experience as a speech-language pathologist, and especially as a mother. She has been in the speech therapy field since 2002, with a range of experience in school programs, private clinics, home-health, and hospital/medical facilities. What she loves most is providing opportunities for parent-involvement in their child’s therapy planning and progress, and parent coaching for greater success. Amanda’s previous therapy experience has given her the opportunity to work with and learn from teachers, occupational therapists and other related professionals. She’s learned a lot about the benefits of adding movement and sensory techniques to provide a functional, productive learning environment for each child. With advanced training in the Lindamood-Bell learning programs, she brings reading, comprehension, memory and visualization techniques into therapy sessions. Her advanced training in Stanley Greenspan’s DIR/Floortime model has taught her the importance of building strong relationships in a developmentally appropriate, child-led, play-based and relationship-rich environment. Most recently, Amanda has created a parent training program using the philosophy and proven success of DIR, called C.A.R.E. for Parents, which walks parents through the process of understanding their child’s strengths and learning style to be able to connect and communicate meaningfully. The combination of these programs among others, has allowed her to create a comfortable, natural setting for the children, where they and their families can thrive. In her free time, Amanda enjoys going for walks, hikes and jogs; spending time in nature with her 3 kids, and painting, jewelry-making and anything else crafty. Amana takes her personal experience of being in speech therapy as a child, along with her own parenting joys, to create a nurturing learning environment for both the child and parents together.

Since we specialize in individual care, at each appointment we devote an hour of 1:1 attention. This gives us ample time to assess your child and devise a program to meet your child’s specific therapy goals. We pride ourselves on a collaborative approach and have a team of occupational therapists and speech and language pathologists. Although your child will work primarily with one therapist, at times we will co treat and collaborate so that additional insight and approaches can be integrated into your child’s care. 

We want you to know that we are always available between appointments via email or phone to answer any questions or concerns you may have.
