A native of Loíza, Puerto Rico, Modesto developed his connection to the arts via his neighborhood movie theater. This early, osmotic exposure to film planted the seed from which his affinity for the arts would sprout. From elementary school to his receipt of a Bachelor of Fine Arts degree from the University of Puerto Rico, Modesto committed himself to his pursuit of creative expression and a lifelong career in the performing arts. Understanding the value of academic education, he graduated Magna Cum Laude and fluently speaks Spanish, English and French. He also trained with the Public Theater and Circle in the Square in NYC. He’s worked more in the silver screen than any actor of his generation, with over 20 films under his belt. Some of his film credits are; “ Animal” alongside Academy Award Nominee Terrence Howard; “Back in the day” working as acting coach for actor/rapper Ja Rule; “Aventura Verde” puertorican film that was presented as a gift to President Barrack Obama in his latest visit to the island and “Any kind of infinite” alongside Goya Award Winner Celso Bulgallo.

His work on stage is also extensive and most recently includes: “Celia; The life and music of Celia Cruz” the smash Off-Broadway musical on which he originated the role of “Pedro Knight” (aka Cabecita de Algodón), husband of the legendary singer whose extraordinarily colorful life serves as the inspiration of the play. The show won stellar reviews and accolades from critics, theater community and celebrities such as Madonna, Paul Simon, Matt Dillon, Laurence Fishburne, Jimmy Smitts, Luis Guzmán, La Chanze, Gloria and Emilio Estefan, Omer Pardillo, La India and Gilberto Santa Rosa to name a few. The international tour included New York, Miami, Canary Islands and Chicago; “La Barbería” the Off-Broadway comedy about a dominican barbershop in Washington Heights ( HOLA Award); “DC-7: The life of Roberto Clemente” the Award Winning musical about the life of the late puertorican baseball player (ACE Award Best Actor) currently playing at the Puertorican Traveling Theater in NYC.
