Monica Lamb Communicative Disorder Assistant Child

Monica A. Lamb 
Communicative Disorders Assistant


Monica comes to Smile Speech Therapy as both an experienced Communicative Disorders Assistant (CDA) and Elementary school teacher.

Prior to starting a career as a CDA, Monica was an educator in both mainstream and special education classrooms. It was during her time as a special education teacher when she saw the enormous impact that intervention could have on speech, language and literacy development as well as the resulting confidence boost in children.

From this, Monica felt impassioned to merge her interest, experience and talents together and specialize by working with individuals as a CDA in a therapy setting.

Monica’s approach to working with children and their families, is to tailor her programming in an engaging, fun, and child-centered way that motivates children to experience success with their goals.

As a CDA for close to 10 years, Monica has worked with toddlers, preschool and school-aged populations in the areas of articulation, motor speech, receptive and expressive language, social communication skills, early literacy and phonological awareness.

Monica thoroughly enjoys working with children of all ages both individually and in small groups as well as working with families in parent-child language and literacy play groups. She has experience using the Levelled Literacy Intervention System©, Wilson Reading System© and is Phoneme Touch and Say© Certified. She is very excited to be a part of the team at Smile.
