Tailored Solutions


A comprehensive assessment is completed to identify the child's current speech and language skills. This includes an interview with parent/caregiver to obtain relevant history, observations of child and administration of standardized tests. An oral motor exam may also be completed for speech assessments to evaluate the structure and function of the mouth.


Based on the results of the assessment, an individualized therapy plan is put together. Recommendations are made for duration's (30 mins, 45 mins or 1 hr) and frequency (weekly, biweekly or monthly).

Individualized and fun

Our sessions are individualized for each client and their family. A wide range of therapy tools and resources are used to create a warm, stimulating environment and to make learning fun. Strategies and/or activities to practice will also be provided for home carryover.

Communication is at the heart of all interactions & is essential for personal, social & academic growth.  Early identification & intervention is key.  It’s never too early nor too late to make an appointment for an assessment.


An articulation disorder means that the person speaks or makes sounds in an atypical way. Their speech may include substitutions, omissions, additions or distortions that make it difficult to be understood. For instance, someone may have difficulty making the correct sounds when using the letters “r” “l” or “s”.​

A fluency disorder is an interruption in the flow of speaking. People with articulation disorders tend to speak with atypical rates or rhythms. They have repetitions in sounds, syllables, words, and phrases. Their speech may be produced with noticeable tension, such as when people stutter.​

A neuro-developmental disorder with a range of symptoms and severity that impairs a child’s ability to communicate and interact with others. It also includes restricted repetitive behaviors, interests and activities. These issues can cause significant impairment in social, occupational and other areas of functioning.​

Childhood Apraxia of Speech (C.A.S.) is a complicated combination of speech symptoms indicating a child’s difficulty sequencing the movements and sounds to make meaningful words. Children with CAS receive individually-tailored intervention from clinicians with unique experience in this area unlike that of more common articulation delays.​

Language-based learning disabilities are problems with age-appropriate reading, spelling, and/or writing. This disorder is not about how smart a person is. Most people diagnosed with learning disabilities have average to superior intelligence.​

A language disorder is impaired comprehension and/or use of spoken, written, or other forms of language. The disorder may affect how the person processes their native language’s form (grammar), content (vocabulary), or function (socially appropriate communication).​

A number of disorders which may affect the acquisition, organization, retention, understanding or use of verbal or nonverbal information. These disorders affect learning in individuals who otherwise demonstrate at least average abilities essential for thinking and/or reasoning. Results from impairments in one or more processes related to perceiving, thinking, remembering or learning. These include: language processing; phonological processing; visual spatial processing; processing speed; memory and attention; and executive functions.​
