Ronn Patterson Owner and Captain of Delphinus

Ronn PattersonRonn is a naturalist by profession, a marine biologist by training, a student of whales by practice, a professional photographer by habit, a teacher by inclination, and a writer by requirement. For over twenty-five years he has led natural history trips to such places as Africa, the Amazon, the Andes, Baja California and Mexico, the Galapagos, and Alaska.

Ronn founded the Natural Environmental Studies Program for the University of California Extension at Berkeley. During the fourteen years he directed that program, he also directed biology instruction and founded and directed the UC Extension Photography Program. In his last three years with the University, he was the Chairperson of the Science and Mathematics Extension.

Ronn’s study of whales led him to co-found the Whale Center, an international non-profit whale conservation group. He has also been a whale consultant and biologist for the U. S. Government as well as a delegate to and member of the Scientific Committee of the International Whaling Commission.

In 1981 Ronn formed Dolphin Charters to offer travelers a rare combination: the enjoyment and celebration of the earth's wonders and a sound natural history education. From October through late April, Dolphin Charters offers cruises in the San Francisco Bay, Sacramento River Delta, and the Pacific Ocean as well as Mexico and the Galapagos. During the summer, Dolphin Charters offers one-of-a-kind journeys in British Columbia and Southeast Alaska.

Dolphin Charters has brought Ronn's life full circle—back to his college training in marine biology—and incorporated his interests in teaching, lecturing, writing, photography, research, and natural history.

Buff and Gerry Corsi

Buff and Gerry CorsiBUFF: She grew up in the Midwest and came to California right out of college on a summer vacation and never went back. She worked for the California Academy of Sciences in various capacities for a number of years, eventually running their adult education program and their members' travel program. When she met Jerry she moved to Santa Rosa and they started up their own company, Focus on Nature, Inc., that offered nature photography trips and workshops. They did that for a decade and then Buff retired into wildlife videography, which has been her life ever since.

JERRY: Jerry was born in San Francisco and grew up to be an oral surgeon in Santa Rosa. He and Buff met in a nature photography class offered at the California Academy of Sciences. Once married, they ran Focus on Nature, Inc. together, and when Jerry retired from dentistry, he took up wildlife still photography and has been widely published in books, calendars, and magazines. As a photography duo, they can have it both ways – if the subject is moving, Buff is pleased, if it is posing quietly, Jerry is happy. Together, they enjoy traveling to wildlife hotspots with their video and still cameras.

Joseph Ferraro

Joseph FerraroJoseph Ferraro started fishing at age four and hasn't quit.  From sunfish to sailfish, Alaska to New Zealand, fishing has been a life-long pursuit. He's fished commercially for salmon and halibut on the west coast, and in Alaska, has caught all five species of pacific salmon.

You don't have to be an expert fisherman to have a good time, and Joseph can help you improve your skills and learn techniques that have worked for him over the years. His expertise combined with the boat's ability to move to "fishy" areas should ensure a good time and fish will be had by all.

Cathy & Gordon Illg

Cathy & Gordon IllgCathy & Gordon Illg have been full time nature photographers since 2000. It was Gordon's degree in Wildlife Biology that began a shift in their photographic emphasis from scenery to wildlife. The wild things and places right in their own backyard, the creatures and scenery from Colorado, started their career. This taught them the valuable lesson that photographers don't need to visit exotic locations to capture great images.

Now the Illgs travel the world trying to capture and display a little of the magic that makes the untrammeled regions and their inhabitants so special.

Their work is widely published and includes numerous covers of magazines like Backpacker, Defenders, National Geographic Young Explorer, Ranger Rick and National Wildlife. Several of their images decorate the tails of Frontier Airlines' jets. After seeing an image blown up to more than 20 feet high on the tail of an airline jet, well even the largest prints are just small.

Twice their images have been displayed in the Museum of Natural History in London when they placed Second and Highly Commended in the Wildlife Photographer of the Year contest. They have also had an image chosen to be displayed in the Environmental Photography Invitational at the Art Wolfe Photographic Center.
