Gregg has been working professionally with natural aquariums, specializing in coral reef systems, for over 25 years. While studying zoology with a concentration in zoo and aquarium science at Michigan State University, he began working with the design, installation, and husbandry of marine aquariums at a nearby aquarium store.
Studying and working with natural marine ecosystems served to spark not only Gregg’s passion for the science of the ocean world, but also the drive to understand its processes and the creativity to replicate it for his clients. In addition to his knowledge and expertise in marine ecosystems and coral reef aquariums, Gregg also is also licensed to teach high school science.
From the time he was a child, when his father began keeping exotic fish, Mark has been surrounded by aquariums. For more than 35 years, he has worked with aquatic systems, ranging from delicate planted discus systems to saltwater aquariums several thousand gallons in volume.
An avid SCUBA diver, Mark has spent time exploring the coral reefs of Cozumel, the Bahamas, and the Dominican Republic. This passion for the underwater world has driven him to master the creation of a wide variety of aquatic systems for demanding clients. Mark, at one time a rescue diver and paramedic for the Glenview, IL fire department, is also the owner of Aqua Visions in Lake Barrington, IL.
