Anne has always enjoyed water sports and has been snorkeling and SCUBA diving since her teens.  In college, Anne chose a Marine Biology class to fulfill her science elective. 

AndrewAndrew Barck
Food Service Director

Andrew was hired as our Food Service Director in April 2018. For the twenty years prior to that, MRDF outsourced the meals for the MarineLab program to a local catering company. When the owner of that company decided to retire, we decided to bring the program back in-house. Andrew came to apply for a position as a part time food service worker, and found himself being interviewed for the Director's position when he submitted his resume and his qualifications became apparent! Andrew plans meals, hires, trains and supervises the staff, and monitors costs very closely in addition to being a hands-on worker in the kitchen. He supervises one year-round worker and seasonal workers as needed.

Mitchell StammMitchell Stamm
Lead Captain
BS Sociology, University of Wisconsin - Stevens Point

Mitch's career has ranged from marine mechanic to solar energy installation project manager to charter boat captain, so he brings a wide array of skills and experience to the new position of MarineLab's Lead Captain. Mitch has been one of our captains for three years while also working for the Florida Keys National Marine Sanctuary program maintaining the mooring buoys from Key West to Key Largo and moonlighting as a SeaTow captain. Mitch joined our team full time in January 2019. In addition to being our main captain, he is responsible for boat repairs and maintenance, compliance with Coast Guard regulations for our captains and vessels, and hiring and training additional captains. His favorite part of working here is listening to the students getting back on the boat talking about all the cool things they've seen on their snorkel trips.

Maintenance Staff

Jorge Zelada & Jesse Hammond work hard making sure that the light bulbs are replaced, the boats are fueled, and the trash and recycling are taken out, all in between their bigger projects repairing and renovating our labs, classrooms, dorms and restrooms. In a facility this large, there's always something that needs fixing!

Housekeeping Staff

Cleanliness is very important when over 5,000 people each year come through our doors! Our housekeeping supervisor Brittany Hammond and housekeeper Gloria "Cuki" Dominguez are responsible for cleaning all the dorms, classrooms, labs, offices and restrooms on the property.
