Newline Behavioral Solutions (NBS) was formed to meet the neurodiverse community’s unmet, unique needs and demand for quality Applied Behavior Analysis (ABA) autism therapy services. As a mother to neurodiverse children and ABA provider, our owner/founder, Jennifer Lewis, MS, LPC, BCBA, recognized ABA therapy seekers may not always have access to quality, personalized services and/or had prior negative experiences with previous providers and deserved better! We are highly skilled and trained in delivering high-quality, individualized ABA services with a strong emphasis on providing each client personalized attention.  ABA is considered the most effective autism treatment-assisting in managing behavioral challenges and skill deficits within the areas such as (but not limited to), socialization, communication, sensory, motor, functional daily living, and functional play.

Contact us today to learn more how we can help meet the individual needs of your neurodiverse child(ren) and family!
