Mr. Guerreiro brings a practical, business-focused approach to his practice, relying on over four years of pre-law experience in pharmaceutical clinical and commercial operations and his education in biology. During his articles, Mr. Guerreiro gained additional perspective on the commercial and regulatory dimensions of the innovative pharmaceutical industry while on secondment to the in-house legal team at GlaxoSmithKline. While studying at Osgoode Hall Law School, Mr. Guerreiro was recognized for achieving top standing in areas including evidence, civil procedure, conflict of laws, business law, and contracts, and graduated second in his class.
