Lori Edwards

In 2008, Lori approached Dr. Compton with an unsolicited and forward-thinking proposition: make the PESL method and materials available to anyone, anywhere using the latest web-based technologies. After years of attempting to offer her services in a rural setting with a limited marketplace, Lori envisioned the ability to assess and train clients via her computer, maintaining the same evidence-based effectiveness that has always been an integral part of the PESL method. She knew there was a robust marketplace for her services, and she was committed to developing her skill set, but she also knew that those opportunities lay beyond the boundaries of her home town in Cottonwood, AZ. After teaming up with a talented programmer who designed the first web-based prototype for web-based PESL assessments, she contacted Dr. Compton to discuss her vision. The rest is everything that (the online hub for web-based PESL assessment) has evolved into. The number of instructors using to grow their independent businesses and expand the reach of their professional services now outnumbers the use of the original printed format of Dr. Compton’s Phonological Assessment of Foreign Accent.

Mark Edwards

Mark EdwardsMark is the other half of the technological/clinical team that approached Dr. Compton with their plans to bring PESL to the web-based world.  With Lori’s clinical guidance and input, he designed the Online Assessment from the ground up. Shortly after that, he applied his technical skills to the development of the PESL Online Practice Lab (, bringing the entire program online and enabling instructors to deliver comprehensive training programs in an exclusive web-based format.

These web-based tools can now be used by any Certified PESL Instructor who wants to take advantage of the speed and convenience of web-based assessment and instruction.  Mark and Lori Edwards remain committed to making these tools a valuable and indispensable resource for accent reduction specialists with continuous developments and enhancements.
