Sammy is a producer with P3 Productions, an artist-driven production company that’s built on three pillars: thought-provoking stories, strong values, and opening doors. They are currently developing: GUN & POWDER, HOW TO DANCE IN OHIO, MIDSUMMER, CHONBURI INTERNATIONAL HOTEL & BUTTERFLY CLUB, and more. He co-founded and launched the company with his partners, Ben Holtzman and Fiona Howe Rudin.

He is a co-founding member of The Industry Standard Group (TISG) and Second Act Theatrical Capital (2ATC), a decentralized leadership cohort of BIPOC producers who came together through a shared affinity and commonality of often being the only collaborator of color in many rooms on Broadway. We seek to create change by re-imagining the pathways to participation within the decision-making levels of theater-making.

Brought up by parents who are educators, Sammy is very passionate about sharing access and transparency within the commercial theatre industry. He is the 2022 program mentor for Theatre Producers Of Color (TPOC) and teaches with The Business of Broadway. He has made presentations and been a part of many theatre panels with Syracuse University, New York University, Center Theatre Group's College and Career Fair for the Arts, SolTalk Podcast, and The Fabulous Invalid Podcast.

Most recently, he is a recipient of The Shubert Organization’s Artistic Circle, receiving bespoke support from The Shubert Organization to help further his career as a commercial producer. In addition, he is on the producing and social media team for The Old Vic's A CHRISTMAS CAROL. In 2018, he made his co-producing Off-Broadway debut with BE MORE CHILL—which transferred to Broadway in 2019.

In 2017, he began his production company, Holtzman-Lopez Productions LLC, with his producing partner, longtime collaborator, and best friend Ben Holtzman. In addition to P3 Productions, they produce the Syracuse University Lewis Hecker Drama Showcase and manage the volunteer alumni group, Orange In The Apple.
