DR SIMON PIERCE
FOUNDER &
EXECUTIVE DIRECTORDr. Pierce founded MMF’s flagship Global Whale Shark Program.

Simon led the research team whose efforts resulted in whale sharks being recognized as globally endangered for the first time on the IUCN Red List, led the technical proposal that successfully listed whale sharks as globally protected via the UN Convention on Migratory Species, and led the first IUCN Green Status assessment of the species. Simon is a scientific advisor to the global shark photo-identification database and a member of the IUCN Shark Specialist Group.

MARK HACKNEY
Chair of the Board
Mark is a seasoned executive with a lifelong passion for marine biology. Throughout his 35 years of diving, he has observed the decline of numerous pristine reef ecosystems, which has only deepened his commitment to marine conservation.In 2014, during a trip to Tofo, Mark and his wife Caroline were introduced to the Marine Megafauna Foundation (MMF) through engaging research presentations on whale sharks and manta rays. They were particularly impressed by the MMF scientists' methodical, data-driven approach to conservation, as well as the organization's dedication to working collaboratively with local communities to promote sustainable conservation efforts.
Having shared many memorable dive trips with Dr. Andrea Marshall and Dr. Simon Pierce, Mark ultimately joined the MMF Board. He is now actively involved in supporting the foundation's endeavors, leveraging his extensive executive experience and passion for marine conservation to help advance MMF's mission.

MMF Ambassadors
TIFFANY SCHAUER
Founder & Executive Director,
Our Children’s Earth Foundation
Tiffany founded OCE in 1998 after many years in various environmental justice and litigation positions specializing in enforcement and compliance. In addition to her private sector attorney experience with Brobeck, Phleger & Harrison, which represented industry in environmental litigation, she was appointed to the Hearing Board of the Bay Area Air Quality Management District (BAAQMD). Prior to her work in the Bay Area, Tiffany worked at the Federal Environmental Protection Agency in Washington, DC in a variety of key roles. She earned her J.D. from Catholic University in Washington, DC. and her B.A. from San Diego State University. Tiffany is admitted to the State Bars of California, Pennsylvania, and the District of Columbia.
Tiffany served in various environmental regulatory roles prior to founding OCE in 1998. Ms. Schauer’s varied positions, including serving as an enforcement attorney at the Environmental Protection Agency, working as a Senior Attorney at a major environmental law firm, and adjudicating Clean Air Act permit disputes at the Bay Area Air Quality Management District Hearing Board. During the course of her career, she discovered that the attacks on environmental regulatory standards and enforcement program funding decisions are not occurring in statehouses and legislative sessions, where the glare of public attention would be too great. Instead, the attacks most often occur in bureaucratic back rooms, out of the public eye, in obscure government departments where polluting industries can influence the decision-making process without risking the wrath of public opposition. The form of the threat is as basic as it is destructive — our environmental laws simply are not being enforced adequately to ensure public safety and basic environmental protections. Since 1998, Tiffany has led OCE to enforce some of the largest environmental law violation actions in the United States.
Over the past 10 years, Tiffany has expanded OCE’s efforts beyond regulatory citizen enforcement to include communicating the issues of government corruption, abuse of power, and needed transparency by addressing these issues in documentary film. Tiffany spearheaded the initiative to bring OCE’s message to the storytelling genre of film through collaborating on many breakthrough documentaries including, Total Denial, Garbage Dreams, Island President, The C Word, Death by Design, How to Change the World, Sempre Fi, Last Animals, and Youth v. Gov.
“Our earth’s marine species and marine habitat areas are critically important, and extremely fragile. MMF’s relentless research, breakthrough peer-reviewed publications, community advocacy, and international coordination, have been critical in establishing the baseline science needed to safeguard our marine giants and the last truly wild places in our oceans. I see MMF as one of the world’s most fearless, effective and financially efficient marine science organizations of our time.”
