Sherry Lazcano

SDI Rescue Diver and Certified Travel Consultant CTC

Travel is my background and chosen career.   Born and raised in Peterborough, I graduated from Sir Sanford Fleming College in Travel and Tourism.  After graduation I never looked back--spending the next 12 years living and working in Cuba, Dominican Republic and Venezuela.


I met my husband, Humberto, while working in Cuba.  He introduced me to the awesome world of scuba diving.  We had the most beautiful dive site in our back yard, The Bay of Pigs.


Braving winter, we moved to Peterborough in hopes of finding a better life. Moving back to my grassroots has been great and we thoroughly enjoy raising our two children here.  I never imagined that one day, I would own my own business.  I love working with our students and seeing their reaction from their first dive experience.  I am very proud to be a part of our local diving community and look forward to many more adventures together.

Alice Gravel-Carson

SDI Instructor

I grew up on Georgian Bay and as a girl was fascinated by everything that swam in the water.  At the age of eight it was, muskrats, turtles and carp and as I grew older, it became everything that I couldn't see under the water.  I loved to swim and did this from May to October every year.  The neighbourhood kids were always the first ones in by May 24 and we were loathe to give it up--even at the end of September. As the third oldest of seven children—all born within 11 years—I had four younger siblings that I taught to swim and cared for at the local beach to make sure they were safe.


My dream was to be a marine biologist and live in Hawaii.  By the time I hit my early 20's, I was married with a couple of children and life happened... I never lost sight of my dream though and when the children were grown, I decided that it was time to do something about it.  I signed up for the Open Water Diver course and I never looked back.


I'm living my dream and it has been more rewarding and exciting than I could have imagined. The inspiration of seeing a spotted eagle ray soar through the ocean in front of you, or one of the most long-lived of all creatures--the sea turtle, swim along side of you or feel the immense power of a shark moving beside you brings realization of how truly wondrous the ocean really is.  Please come and join me as I'd love to share this experience with you.

SDI Instructor

As an artist and a naturalist, I've always had special appreciation for the underwater world. Growing up with aquariums and Jacques Cousteau documentaries, scuba diving was a life-long dream.


In 2000 I received my Open Water Diver lessons as an anniversary present from my wife, opening up a whole new world of adventure, travel and friendship. I've had great dives across Ontario, BC, the Caribbean, Galapagos and Fiji in the South Pacific.  I look forward to many more great diving adventures.


Introducing new divers to SCUBA has been one of the most rewarding and enjoyable experiences of my life.

Kathy Manson

SDI Divemaster

I had been snorkeling for a few years while on vacations and on one vacation in Tanzania we were snorkeling with dolphins and that was the moment I decided it would be better to be under the water then on surface. 

I started my diving course for Open Water in January 2012.  Following that training I continued my education, diving and training throughout Ontario and the Caribbean.  Diving has opened up some wonderful places for me including amazing underwater environments and a desire to learn and develop skills but also to teach and share with others so they are able to experience all that I have.  Diving has become a very important part of my life.  I strive to educate myself, improve my skills and help others to do the same.  With my instructors from Adventure Divers and friends in our dive community moving onto the SDI Divemaster Course was a very easy decision to make.  I successfully completed my Divemaster Course in September 2015.
