Sammy is a co-founder and 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 (World Premiere: Signature Theatre 2020), HOW TO DANCE IN OHIO (World Premiere: Syracuse Stage, 2022), MIDSUMMER (In Development), BRADICAL (In Development), and two additional projects in development with award-winning artists John Leguizamo and Shakina Nayfack. He launched the company with his partners, Ben Holtzman and Fiona Howe Rudin. Co-Producing credits include A CHRISTMAS CAROL, BE MORE CHILL, THE KITE RUNNER, and A STRANGE LOOP (Tony Award with A Choir Full Productions) on Broadway and ORLANDO in London's West End.

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. 

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 is a part-time professor at Syracuse University and has participated in theatre panels with New York University, Center Theatre Group's College and Career Fair for the Arts, SolTalk Podcast, and The Fabulous Invalid Podcast. 

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 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.
