what we do









why rockford speech therapy

Rockford Speech Therapy is unique because of its flexibility and personal attention. We understand how concerned you are about your child's development, so we offer personalized attention with therapy carefully tailored to each child's needs.

Balancing work, family, and daily demands can be a struggle; that's why we strive to provide convenient therapy times, including after-work , to fit your hectic schedule. We also offer multiple ways for you to access therapy, including in-office visits, teletherapy, and even home visits. We accept several health insurance plans to address your financial concerns, including Medicaid.


​We serve various clients at Rockford Speech - from children to adults. We assess and treat children who have developmental and language delays, speech and oral motor issues, stuttering, and children on the autism spectrum. If your family is bilingual/multilingual, our Bilingual Speech-Language Pathologists can determine if your child has a language disorder or if they are simply learning multiple languages. We have a passion for bilingual development and would love to help your family find the best ways to integrate languages spoken in the home. We also serve adults for accent modification coaching and stuttering therapy.

Liv Baker M.S. CCC-SLP
Speech Language Pathologist

Hi there, I'm Liv (short for Olivia)! I have been a speech-language pathologist at Rockford Speech Therapy since January 2022, working with pediatric and adult populations. Within the pediatric population, I primarily work with articulation/phonological disorders, language disorders, executive functioning disorders, fluency disorders, and autism spectrum disorders. Within the adult population, I primarily work with those with aphasia, executive functioning disorders, autism spectrum disorders, fluency disorders, or traumatic brain injuries. I am also working through John Barnes' myofascial release seminars and plan on incorporating my skills into my sessions. I push my clients to their fullest potential, make therapy as fun and functional as possible, and tailor it to them and their goals. In my free time, you can find me doing hot yoga, reading, knitting, or playing with my kitten! I currently live in Grand Rapids with my kitten. I love being part of the Rockford Speech Therapy team!
