The sales, service and dive staff at Minnesota School of Diving are the people who are chiefly responsible for making scuba diving experiences with MSD so enjoyable for our customers. All of our staff started out as diving clients and while progressing through training and participation in diving activities, these individuals demonstrated an understanding and agreement with MSD'S philosophical approach to scuba diving; essentially - creating a positive, compassionate and nurturing environment for training; and organizing fun, social, and exciting experiences, which allow divers opportunities to enjoy their underwater passion. Here at Minnesota School of Diving we appreciate everything the staff does using their experience and knowledge of scuba diving to ensure a fun adventure for all of our customers.

Cory Hines
PADI Divemaster

Original Certification Date: June 6th, 2013


Diving History: I started diving because Nick Haglin asked me if I was interested and once I took the class I was hooked. I spent the next few years logging dives and getting the Advanced Open Water Diver certification. Places I have travelled to dive are: Bonne Terre, Tobermary, Puerto Rico, Straits of Mackinac, Alpena, Roatan, and Glacier National Park with plenty more to come. 


Some Favorite Dives: My most memorable dive would be when Paula Persons decided that floating around the surface was more enjoyable than diving at the Straits of Mackinac. The second would be my first ocean dive in Puerto Rico; just the change from Minnesota diving to the clear water was amazing. My favorite local dives would be Seaward, Wombad, Feigh, and anything in Huntington.

David Hillstrom
PADI Divemaster

Original Certification Date: May 15, 2016. It snowed each day of the Open Water dives!


Diving History: After wanting to learn to dive as a teenager while watching divers from the surface while snorkeling, I finally found the opportunity to sign up for my open water course an was able to fulfill a life goal some time later. Every few years since my certification I decided to take the next advancement course in diving. I wanted to gain experience prior to completing the next course. I've been fortunate enough to make great friends to dive with and have learned a lot from each of them. I now enjoy diving with friends, newly certified divers and a great community at Minnesota School of Diving. All of these experiences and training has also offered the opportunity to offer my services as a member of the Crow Wing Country Rescue and Recovery Team. 


Some Favorite Dives: Some of my favorite dives have been in Cozumel along the steep walls and swim throughs. Floating along and taking in the scenery is really nice. I've also enjoyed local dives in Minnesota. The Crosby Mine Pits offer something new each dive. The Tioga Mine Pit was also a great dive. 

Day Job: I am the Senior Regional Manager of PLM Lake and Land Management Corp. Midwest Region. We manage aquatic invasive species for landowners, associations, lake improvement districts, watersheds and government agencies. I'm fortunate enough to spend nearly five days a week on Minnesota lakes during the open water season. 


Other Interests: I've always been an avid user of the water. My family enjoys spending the day out on the boat and swimming. Wakesurfing is a great way to spend the day with the family. Target shooting and trap shooting and enjoyed in the early spring and fall. 


PADI Specialties I Am Certified In:  Although I don't hold a lot of specialty certificates I've been fortunate to complete many dives that are the bases of the specialties.
