Who is Marnie Loeb?

Marnie Loeb

Marnie Loeb, M.Cl.Sc., SLP(C), Reg. CASLPO is the owner and operator of Motor Mouth Speech & Language. She is an experienced Speech-Language Pathologist, knowledgeable in both paediatric and adult communication and swallowing disorders.

As a teenager, Marnie started a small business as a piano teacher. Through this, she honed her one-on-one teaching skills and realized she had a gift for finding ways to motivate her students. However, she always dreamed of being a journalist and reading the evening news. One day, her mother showed her a newspaper article about Speech-Language Pathology, and instantly the connection between her two passions was realized. Marnie has enjoyed a rewarding and successful career in this field for almost fifteen years and hasn't looked back!

Music continues to be a big part of Marnie's life. You may see her playing piano and accordion in the family folk band “The Gee String Pickers” at community events. In addition, Marnie competed for the last three years on the Ontario Curling Tour, with competitive curling taking a backseat more recently to club curling at Guelph Curling Club, where she is a member. Summers are filled with camping and cottage trips, along with several nights a week of recreational sports teams (Ultimate Frisbee and baseball).

Currently Marnie works part-time for Speech-Language and Audiology Canada as the Speech-Language Pathology Advisor. Her role is to coordinate and facilitate special projects on issues relating to the professions, including position papers and standards of practice. In addition, Marnie has been appointed to the Board of Directors at Guelph Community Health Centre, where she is involved in the strategic direction of the organization as well as approving new initiatives that affect the Guelph community.
