Riffat Rehman. MS CCC SLP

Owner of Main Step Therapy LLC

Riffat Rehman is a licensed speech and language pathologist and the owner of Main Step Therapy. She has a masters in Communication Disorders from East Carolina University. A multilingual and multiethnic competent, she is fluent in English, Urdu, Hindi, Potohari and Punjabi and thus can relate to parents and caregivers that makes up today’s diverse population of Metroplex cities. She has extensive experience in working with all age groups (birth to 3, school going, adults), in variety of settings (home health, clinic, daycare centers/ ABA centers, public and private schools, rehab/ hospitals). Most of her experience however comprises of evaluation and treatment of individuals learning English as a second language. 

Other than being able to relate to multiple cultures, she also brings to table the perspective of a mother of 24-year-old, special needs son, who is on spectrum. Prior to her training as a speech therapist, her career started in business industry after her first masters in Business. Shortly after that, her son was diagnosed with autism. She dedicated her time to run an in-home program to supplement school for her son. She got training in TEACCH, ABA and other techniques to understand and implement the program. In 2007, she got the funding approved for her son to go to a private autism school. Once he was on track to progress, she went back to graduate school to become a speech and language pathologist. She got great opportunity to work with bilingual population in low SES campuses of Glendale Elementary School District in Arizona. In 2016, she moved with her husband and three boys to Dallas, Texas where she started working for Frisco Independent School District (Early Childhood School). In 2018, she opened her private practice. 

The growing diversity in student body in district, and Metroplex in general is resulting in challenges and adjustments to service delivery strategies, both for general ed and special ed. The sensitivity of culture and language is an important factor when evaluating and treating students who speak two or more languages. Recognizing the need to provide support and work directly with these families became the impetus to opening a private practice and Main Step Therapy came into being. Initially Riffat ran the practice out of home and recently got a clinic to accommodate her caseload.
