Later, Bridget dived in locations that don’t include Raja Ampat, Lake Baikal, and the Arctic Circle.  Instead, she flew around the world for her job with an airline and later joined Underwater Adventures to work in the store. She completed her PADI Divemaster certification in 2012, AI in 2015, and now joins the ranks of Instructor having completed her Instructor-level training in 2018.  In her spare time, Bridget is a Roller Derby Queen, skating under the moniker “Sandy Hook-Her”.

Chris Peterson

Chris Province
IDC Staff Instructor

Chris did six resort dives with his wife over the years until his wife finally signed them up to get certified while in the Bahamas in 2007.  Since then, he is sure there are times when his wife must question that decision, because almost every weekend during the diving season he is in the water rather than at home mowing grass and doing chores. Chris is now a IDC Staff Instructor and teaches many specialties.  In addition, he is certified as a PADI Tec Gas Blender, PSI Tank Inspector and Scubapro and Cressi regulator technician. He has been lucky enough to dive many places around the world.  However, as the saying goes, there is no place like home, and his favorite place to dive is the wrecks off the New Jersey coast.

Scott Savarese

Katie began her scuba diving career as a volunteer firefighter when she was 18 years old. Being a firefighter & EMT at the Jersey Shore, she worked her way up in the ranks bringing many technical skills to the position including Technical Rescue, Rapid Water Rescue and Marine Operations to name a few. When natural disaster Hurricane Sandy hit her town, even our firehouse was underwater. This was the moment she decided to become a PADI divemaster.  

Lucas GuarinoLucas Guarino

Lucas wandered into Underwater Adventure Dive Center in 2010 and has since worn a spot in the couch.  It was a good run, but in 2021 he was told, “either pull your own weight or pay rent”.  Because all his money was going towards diving gear, he decided to get certified as a Dive Master in 2021.  Lucas enjoys blowing bubbles any chance he can get.  Some of his favorite spots include Grenada and Dutch Springs.  When he’s not diving, he enjoys spending time with his family and cooking.

Felipe Siqueira

Known as Phil to students and Wrong-way Corrigan by the staff, was looking for the next adrenaline high when his father recommended he get certified as a scuba diver back in 2012. He came to UADC for his Rescue Diver certification in 2015 and never left. He received his Divemaster certification in 2019. His favorite place to dive is the NJ coast, and while most complain about the low visibility, he maintains that it just makes every other dive where the visibility is 5+ feet that much better. It is also rumored that this is why he steers away from pool sessions, visibility is just too perfect and he has no excuse for going the wrong direction when using a compass.

Trish Zwolinski

Trish became a divemaster in 2018 while doing conservation work on sharks.  She is finishing her masters degree in Coral and Marine Predator Conservation in October.  Trish enjoys blowing bubble whenever she can. She is currently transitioning to become a PADI Instructor.
