Dr. Pellegrini established Central Overseas Education Services in 1994 and is a TESOL Instructor. He has an extensive education background holding a Bachelor's degree from the University of Waterloo, a Diploma in Technical Education and B.ED from the University of Toronto, a Masters of Education from Niagara University, and a PH.D. in Education from The University of New Mexico. He also holds a Certificate in Gerontology from Toronto Metropolitan University (formerly Ryerson University) and Music Teaching qualifications for both Choral and Instrumental Music.

As an academic, he has taught in teacher-training programs at York University and the University of Toronto, including post-graduate certification courses for licensed teachers, as well as in the Masters of Education program in New York State. He has also represented various American and Canadian Universities for the purpose of international overseas admission and served as a Mentor for adults wishing to fast-track their own personal degree studies. Being labelled as a "retarded child" in first grade gave rise to his passion for caring for special education children and for designing and assessing instruments for more accurate testing. Designing individual programs for children and post-graduate adults aspires from the "education from womb-to-tomb" model in coaxing and inspiring individuals to strive higher and higher in their personal and professional lives. And the role played by Morgan Freeman in the "Shawshank Redemption" brings out the famous line that inspires all of Jim's work: "get busy living or get busy dying".
