About Elizabeth

Elizabeth Peterson M.S., CCC-SLP
Speech-language pathologist, speech coach and practice owner

For over 20 years Elizabeth Peterson, has enjoyed supporting individuals and companies with their communication and voice needs. Speech and Voice Enterprises, her private practice, has been in operation for over 15 years in Denver, Colorado. Ms. Peterson is heavily involved in her field and has numerous published books, therapy programs and articles in the areas of accent reduction, public speaking, leadership and communication, traumatic brain injury, stroke recovery and pediatric therapy programs.

She is a national speaker and trainer and shares her expertise at state conferences, speaker bureaus and does on-site training for companies in Denver and nationwide. She served on the board for the Colorado Speech and Language Hearing Association for three years and was a consultant on the brain injury team for the Cherry Creek School District for five. Her current, unique niche is demonstrating and teaching the relationship between how one uses their voice, communication style and how it relates to their leadership persona. She is passionate about being a speech therapist and has positioned Speech and Voice Enterprises to be Colorado’s strongest company for all communication needs.

On a personal note, she loves the Colorado lifestyle. It would not be unusual to find her biking on some mountain road or skiing down a lovely trail. She has the travel bug and has a soft spot for animals. Munchkin was our lovely therapy cat for several years. Even dog lovers looked forward to their session with Munchkin.

“Liz is awesome. She has provided me with all the best tools to implement in my setting. I am effectively communicating in my meetings and presentations. She is full of so much energy. Liz is a true expert and professional. She is able to take a concept and break it down into useful information you can use beyond the class.”

- Aileen

“Her class has taught me to slow down. Liz’s teaching style is so different from what I have had before. She is about how to deliver that message clearly and with impact. She also focuses on how you sound. You know that when you sound good that you are confident. She knows that based on how you sound is how you will appear. Her training has helped me so much. I feel ready to deliver a presentation.”
