Mexican bow maker and restorer, Humberto Nicasio graduated with honors from the School of Violin Making at the National Institute of Fine Arts in Querétaro, Mexico. He has taken courses and workshops in Mexico, Spain, the Netherlands, and the United States.

Humberto began making baroque bows during a course taught by Marie-Eve Geeraert in Mexico City. He later focused on building baroque and Renaissance instruments at the Escuela de Violeros de Zaragoza. He studied baroque bow-making techniques with Luis Emilio Rodríguez Carrington in The Hague.

In the United States, he has participated in the Violin Society of America's summer programs at Oberlin College and Learning Trade Secrets, both focused on modern bow making and restoration. In these programs, he received instruction from David Forbes, Jerry Pasewicz, Matt Wehling, Peter Oxley, Rodney Mohr, and David Orlin.

He studied music at the Faculty of Music at UNAM, specializing in historically informed performance on cello and viola da gamba. He also holds a degree in Geomatics Engineering from the Faculty of Engineering at UNAM.

In 2023, Humberto relocated to Boston to work full-time as a restorer and bow maker. Eager to continue developing his career and refining his skills, he initially worked at The Carriage House at Johnson Strings, and in 2025 he joined Reuning & Son Violins as their resident bow maker.
