Welcome To Our Clinic

Lindegard Therapy provides Applied Behavior Analysis & Speech Language Pathology  services in Beaverton and Hillsboro, Oregon and its surrounding areas. At Lindegard Therapy, we know that all children can learn but that some children learn differently than others. For this reason, we offer treatment that is tailored to the individual and built on a solid family-centered platform. Our interventions focus on improving your child’s social, communicative and daily living abilities by creating a learning-rich environment designed to target these skill areas, while also maintaining an open and collaborative relationship with you as the family.

Our Approach

At Lindegard Therapy we believe that a combined and collaborative approach to therapy is most beneficial to your child. For this reason, we combine both services to develop research-based holistic practices that best fit your child’s needs. 

Quality (not quantity) is most important to us. Every family is unique and there is no one prescribed method for conducting therapy and working with families. We believe wholeheartedly that the family drives the service delivery model and that your input and participation is at the core of treatment goals and progress. We take time to build strong and lasting relationships and understand that YOU play the biggest role in your child’s life.

Our Core Values

The 5 C’s


All of us, kids included, learn through repetition, and therefore consistency is key to providing effective therapy. Our sessions are routine-based which keeps kids on track and optimizes learning opportunities for successful treatment outcomes. 


Integrative collaboration is built into our therapy model to ensure that goals are being addressed through a multi-disciplinary lens – Rather than sending families to multiple therapy clinics to meet their child’s needs, we provide all necessary services in house for your child to thrive – Speech Therapy (ST) & Applied Behavior Analysis (ABA).

Child-centric care

Good quality therapeutic services center around the individual child and their therapy team – every child is different and requires a unique approach to therapy; we provide ongoing support and intensive supervision to ensure high quality of care. Each child receives the one on one attention that they need to succeed and each clinician receives ongoing direct supervision beyond board standards.


At Lindegard Therapy building a sense of community is as important for each child as it is for each therapist to foster an environment conducive to growth and understanding. Everyone has individual strengths that should be recognized and nurtured.

Clinician development

All of our clinicians are dedicated and compassionate when it comes to working with kids and families. Child development is our focus and professional development helps clinicians provide more effective treatment to meet the goals we set for our clients.

David Garder



Speech Language Pathologist and Board Certified Behavior Analyst

David's love of language inspired him to earn a B.A. in linguistics from SUNY, Albany in 2003. During his undergraduate studies, he became familiar with different theoretical frameworks that examine the universal structure of language. He wanted to apply this knowledge in a practical and meaningful way, so he gravitated to the field of Speech Language Pathology. In 2009 he earned an M.S. in Communicative Sciences and Disorders from California State University East Bay and has been treating children with speech and language disorders since. In 2018, David earned an M.Ed. in Applied Behavior Analysis from Arizona State University.

David specializes in helping young children with autism who have Apraxia of Speech learn to start making sounds and use words to get their wants and needs met. David combines principles of Linguistics, Speech Therapy, and Applied Behavior Analysis to help address speech needs in young children with autism.

When David is not working with kids, he enjoys fly fishing, white water kayaking and hiking.
