Born in Nashua, New Hampshire to Jackie and Ray Bernier. Attended both Grammar and Junior High School in Merrimack, New Hampshire, where the stage first "discovered" Marlo. Attended Sanborn Regional High School in Kingston, and directly after graduation served four years in the USAF, in both California and Germany. Shortly after being discharged from the Air Force, returned and resided as an "Ex-Pat" in Wiesbaden, FRG, playing music in a few bands on the club circuit in Germany, until the end of 1985.
However, it was another five years before returning to the stage in; I Never Sang for My Father. In Baltimore, Bernier spent the better part of a decade on the stage, delivering solid stage work in AXIS Theatre's; Angels in America, Love!Valour! Compassion! & God's Country.
Though not the only stage in Baltimore where Marlo worked, but her "heart" will always be with AXIS Theatre and Brian Klaas(Artistc Director) and Jon Lipitz(Managing Director), with whom Bernier joined in producing 10 seasons of some of the most artistically fulfilling theatre in her career to date.
In television, Bernier guest-starred in Cold Case on CBS; in Homicide: Life on the Street, on NBC; on Las Vegas, for NBC, & the Book Shop Merchant on Alias, for ABC in the episode; I See Dead People. Marlo has also enjoyed various leading and supporting roles in both indie films and major motion pictures, including the leading role opposite Jennifer Fontaine, in their collaborative work, The Last Time We Were... and though her scenes were cut from the final edit, she has unequivocally stated; that working with David Fincher on Zodiac, was just about the coolest job she's ever done, and what Marlo got from watching David direct, would inspire her to finish writing Glass Houses and move it into its pre-production phase.
With their first collaboration on the gripping short; The Last Time We Were..., Bernier's, Jackie Frost Films and Fontaine's, Scorpio Rising Films, garnered a Silver Remi at WorldFest/Houston 2006.
Bernier is also eternally grateful to Suzie, for her continued encouragement and belief in "the dream".
