Giles has been instructing and guiding dives in Cayman since 1995. Firstly with Bob Soto's Diving for over two years and then with Divers Down where he enjoyed the freedom of diving with small groups. This has given him a wide range of experience with both large boats and large groups and small boats and small groups. With Wall to Wall Diving he aims to combine the best of both worlds: large boats and small groups.

Giles is a PADI Open Water Scuba Instructor, Medic First Aid Instructor and Underwater Photography Specialty Instructor.

After many years of traveling and diving around the world Deanna decided that Grand Cayman was the place to stay (nothing to do with Giles!) A tough decision to make after having just spent a year instructing in the Philippines! Deanna also started her Cayman diving career at Bob Soto's Diving; then followed a short time at Indies Divers and a year diving for Atlantis Submarines. She welcomed the chance to instruct and guide dives again with Wall to Wall Diving.
