SCUBA Instructor


I have always loved the water. I worked as a professional swim instructor for three years prior to becoming a certified scuba diver. I became a certified scuba diver while still in high school and I was hooked! I knew I wanted to share my passion for the underwater world with others so I increased my knowledge and through the SSI dive education system and became a professional dive instructor. 

When I'm not in the water, I enjoy hiking and spending time with loved ones.

Course Director


I’ve been scuba diving since 2007. I truly fell in love with the ocean and the vast variety of aquatic life is so very engrossing. There is so much to learn and know. I am recently retired from law enforcement although I still volunteer. I have experience with public safety diving (7 years) and I teach most courses from recreational to professional levels.  I met my husband scuba diving and he is certified as a Divemaster. We are always diving. Our son also enjoys diving. 

Recommendations to all divers:  Keep learning and dive..  There is always more to learn.
