he learned to dive in 1978. He became a NAUI instructor in 1980, and
has since become a NAUI Instructor Trainer as well as PADI instructor.
John is also certified as an ice diver and a cave/cavern diver, as
well as holding certifications in advanced nitrox and tri-mix. With
more than 4,000 dives throughout the Midwest, Florida, and the
Caribbean making nearly 200 dives a year, John has added underwater
photography and videography to his arsenal of interests and has taken
thousands of underwater photos. In addition to his interests in
instructing and recreational/technical diving, John also enjoys his
newfound duties as owner of IID.
Ione Perhay

Ione, is the co-owner
and John’s partner at IID. She is not new to IID either.
Ione was certified in 1986 and began assisting with classes, OW
training and several trips to the Caribbean. She became a NAUI
Assistant Instructor in 1988.
With close to 1,200 logged dives, Ione continues to dive throughout
the Midwest, Florida and the Caribbean. Recently she has taken
up digital photography. If you want to know the name of what you
saw, Ione is the one to ask. This biology teacher can identify
creatures, coral and fish with the best.

William (Bill) H. Instructor
First certified by IID in late 1996, Bill continued scuba instruction
to became an instructor in June of 1998. Early dive trips
included a Blackbeard’s live-a-board, Cozumel, and Narragansett Bay,
RI. Bill studied to become a cave diver with Bill Osterich in
Crystal River and has done numerous trips to the Florida springs areas
both with and without students. “Rainbow River, in Dunnellon, is
still one of my favorite dives”, he beams. Numerous dives to the
Florida Keys include the USCG Duane and Spiegel Grove, the City of
Washington, the Benwood, Joe’s Tug, and the Cayman Salvager.
Most recently, he encountered a whaleshark while completing the wreck
of the Captain Dan in Pompano Beach. “Unfortunately, I left my
camera on the boat because the surface current was so strong”, he
reports with a frown. Other exotic dive trips include Bonaire,
Roatan, Curacao, and Marsh Harbor, Bahamas, and Bonne Terre, MO.
On Wednesday mornings, Bill joins a small group of volunteer divers at the Shedd Aquarium where he works with the Marine Mammal Department to maintain habitats for the beluga whales, Pacific dolphins, sea otters, and other critters in the Shedd’s exhibitions. Bill has worked at Shedd five years and has 150 of his 600 dives there.
An avid videographer, Bill has recorded many of his adventures to digital video.
“Stop into the shop and I’m happy to show them anytime.”
