Dave Gansemer

Independent Assistant Instructor

Dave has been diving since 200. In 2017 he began diving with Sub-Aquatics Sports. As a result, he drew a higher interest in diving not only as a fun and recreational sport, but also in an academic capacity. In 2022, Dave completed his NAUI and SSI Assistant Instructor program certifications. He also plans to participate as a travel guide on dive trips and work towards the completion of the Instructor Certification. Dave’s diving experiences have included Michigan local lakes, Great Lakes’ shipwrecks, Grand Cayman, Mexico, the cenotes in the Yucatan Peninsula and other Caribbean destinations. His diving goals and interests are to simply spend more time in the water, be more active in the dive community, explore new dive destinations and train others.

Jim Allen

Independent Open Water Diver Instructor

Jim was originally introduced to scuba diving by the British Sub Aqua Club while studying as an exchange student at the University of Surrey; England in 1983. He overheard a diver telling an adventure story and asked to join the table. They took him into the club and taught him how to dive. His first open-water dive seemed simple enough in the English Channel on a WWII wreck. Every weekend he went wherever the club was diving and eventually did all the dives required to become certified. Upon returning to the U.S, Jim joined an SSI shop in Lansing, MI and earned his Divemaster certification. After retiring from the Army Reserve, he found the time to further his professional dive career and ultimately got certified as an Instructor in 2020.

Megen Batway

Independent Dive Professional

Megen has long been a familiar face around SASS, and is looking forward to continuing to grow with us as Diventures! She was first certified in 2012 and was immediately bitten by the diving bug. Megen completed the NAUI Master program with Rick, and also obtained certification from Dive Rescue International, which she uses to serve on Kalamazoo’s County Dive team. At the top of her dive bucket list is Cocos, Guam and Truk Lagoon. In her own words, “It’s not so much location for me, as what I’ll see and do. I want to swim with whale sharks, explore shipwrecks and dive among phosphorescent marine life.”

Tim Coffing

Independent Dive Professional
Technical Diver

For those of you who’ve been with the shop a long time, Tim is a familiar face. He has been diving since 1983. His Open Water Training dives were a nighttime lobster hunt. He has been to Belize, Cayman Brac and the Bahamas. Tim looks forward to diving more locations in the future. Certified as an Ice, Advanced River, Heliotrox and Trimix diver, he has a lot to show for his many years of diving. Tim is also Technical Dive certified through NAUI, and his favorite local wrecks have been the Cornelia Windiate, the Typo and the Florida. His reason for diving is, “Breathing underwater is one of the coolest things a human being can do.”
