While studying Spanish as a foreign exchange student in Mexico, Lynn McGrath bought a guitar on a whim and asked a visiting professor, Alfredo Sanchez, for lessons, never imagining that years later she would be invited back as a professional musician. Since then, Lynn has performed in multiple international festivals including the XIX Festival Internacional de Guitarra in Lima, Peru, the Guitar on the Mediterranean Festival in Italy, the Nikšić Festival in Montenegro, the III Muestra de Guitarra Ajijic in Mexico and for the 2009 Guitar Foundation of America Convention. In her unique rendition of Platero y yo by Castelnuovo-Tedesco, Lynn has astounded audiences and received critical acclaim by performing the role of guitarist and narrator simultaneously.

Lynn has performed and given masterclasses for prominent guitar programs including The University of Veracruz in Mexico and Oberlin Conservatory, and has appeared on a number of arts series and for colleges across the United States. In 2008, she completed a 6-concert tour of Peru, and has been an outreach artist for organizations such as the Austin Classical Guitar Society and the Da Camera Society in Los Angeles. She has appeared as a soloist with the Northern New York, has adjudicated a number of international competitions, and in 2009 was the selected as the clinician and conductor of the Albuquerque Honors Guitar Group.

After having received degrees in Spanish Language and Literature, Education, and in Music, Lynn received her Master and Doctorate of Musical Arts Degree from the University of Southern California. She has studied with some of today's most prominent guitarists, including William Kanengiser, Pepe Romero, as well as James Smith and Douglas Rubio. Lynn is a former faculty member of the Crane School of Music, State University of New York at Potsdam, where she received a Student Choice Award in 2006.
