AmpOnTheAir Voice Over Demos
A voice that makes your audience stop, listen, and feel something.
Hi, I’m Marissa — a San Francisco Bay Area voice over artist and actor bringing warmth, clarity, and range to eLearning, explainer videos, commercials, and live performance promos. If your project needs a voice that connects, let’s talk.
A little about me:
I’ve spent 28+ years in biotech documentation at Genentech and founded AmpOnTheAir Productions in 2013. I began stage acting in 2017 — because great voice work and great performance come from the same place: genuine human connection. I’m a member of NAVA and VO Pro, and I record from my professional home studio in San Bruno, CA.
Your project deserves a voice people actually connect with. Book a free 30-minute consultation — no pressure, just a conversation.
I am a Technical Creative located in the San Francisco Bay Area. Born a Filipina-American in the Central Coast of California and raised with Pilipino traditions, culture, food, and language (Tagalog) by Pilipino immigrant parents. With an elementary school teacher mom and a traffic engineer dad, it’s no wonder I enjoy learning new (and complex) things and having a passion to teach it to others when given the opportunity.

When I was young, I pretended to be a commercial by reading the sides of cereal boxes. You know the short story or summary about the cereal or the box of ice cream? Yea, those! As I got older, I became interested in reading those patient/physician inserts found with your prescription. You know the folded up paper that you typically don’t bother reading? Yup! I liked pretending I was a commercial when reading those aloud to myself, too! Little did I know that you can actually get paid to talk aloud about products on television and radio, as well as educating learners from the computer at work (or at home. Thanks, 2020 pandemic!)


Fast forward to 2011, after being laid off from a major biotech company, I finally take an introduction class to voice overs. After taking more classes, I recorded my demos. In 2012, I started contracting with my former company utilizing my project management and quality assurance skills, and then reconnecting with former colleagues. One of them happened to be an instructional designer. When she found out that I have been training as a voice over artist, she suggested that I record eLearning modules for them. By 2013, I became the founder/owner/voice over artist of AmpOnTheAir Voice Overs, as well as becoming an approved vendor for my former biotech company (while still also contracting with the device development group as a project manager and as a quality assurance document specialist). My first paying voice over (VO) gig was recording my first eLearning module for the device development lab! As I continued to train as a voice actor, I also trained as a stage actor, which led me to my theatrical, acting debut in 2017, where I also recorded their promotional trailer to advertise the production.

play. I’m in this video during rehearsal.
