Kate grew up on the coast of Virginia, where most of her early memories involve saltwater, beaches, and spending time around boats. That early connection to the ocean eventually shaped both her career and her lifestyle.After graduating from the U.S. Coast Guard Academy with a degree in Marine and Environmental Science, Kate spent years at sea serving in leadership roles across the Caribbean, Pacific, and North Atlantic. Her time in the Coast Guard included search and rescue, law enforcement, and long stretches on the water that only deepened her skills as a mariner and her respect for the ocean.While stationed in Key West, she rediscovered scuba diving and eventually transitioned into the dive industry, where she’s now been working professionally for over eight years. Today, she combines her background in seamanship and diving as a captain, instructor, and guide, focused on running safe, smooth, and enjoyable trips for every guest who comes aboard.Outside of diving, Kate is just as comfortable pushing endurance goals on land, including multiple half marathons and triathlons.Fun fact: she’s spent about half her life behind the helm of something—from small boats to massive ships—but still gets excited every time she gets back out on the water.
