Theresa Guise is an award-winning photographer who uses her images to promote conservation of our planet and the animals within.
The marriage of marine biology and photography started in 2006 when Theresa learned scuba diving and underwater photography. 

Armed with just a point and shoot camera, she set out to document what she saw underwater. 
Since then, this passion has taken her world-wide to experience different microenvironments beneath the sea, which parallel her study of cancer microenvironments as a physician-scientist. 

She has co-authored diving articles on Fiji, Cuba, Galapagos, Maldives and other topics in Diver UK, Duiken, Onderwater Sport, Tauchen and Duikenbeld. 

Her photographs have appeared in The Guardian, National Geographic, Cosmopolitan, Daily Express, Scuba Diving, Live Science, RealClear, SeaUnseen, Yahoo News, MSN News, Caters News and Earth Touch; including cover images for Nature Medicine, Diver UK and Onderwater Sport. 

Theresa has won awards in Underwater Photographer of the Year, Ocean Geographic, Deep Indonesia, Lens Beyond Ocean and United Nations World Ocean Day international competitions and was the featured Photographer of the week in Dive Photoguide as well as Onderwater Sport. 

She has judged photo competitions in South Africa, Florida, Cayman Islands, Hungary, British Society of Underwater Photography and more. She co-coached the Women’s Underwater Photography Team for the Dutch National Championship. 

Theresa presents lectures on shark conservation, underwater imaging and uses underwater imagery in her scientific presentations and publications. 

She contributed to Planet Aqua, featured on Swedish National Water Day. Dr. Guise is an endocrinologist and professor at The University of Texas M.D. Anderson Cancer Center where she provides health care to cancer patients with bone disease and directs a research laboratory to study how cancer grows in bone. 

Her research interests in the bone microenvironment parallel her study of different microenvironments in the ocean and have been funded in part by Dive into The Pink, a non-profit organization that supports cancer research and advocacy.

José Sánchez Garrido was born in Málaga, Spain in 1959. However, he lived in Barcelona from an early age, a city where he also began scuba diving back in 1987. His interest in underwater creatures grew, which prompted him to start in the world of underwater photography in 1992.

Thanks to his knowledge in industrial machining, he made his own housing for his camera (Canon 500D), with which he participated in numerous photography events. He got the 1st place in international photography in the magazine "Unterwasser" in 2001. He also participated in several championships in Catalonia, managing to become champion with the company and collaboration of his wife Patricia Cárdenas. He also had the great fortune to participate in the national championship, managing to finish runner-up along with his friend and photographer Marc Casanovas.

In 2006 he decided to make his profession his passion, creating the company SAGA DIVE S.L. From then on, he is fully involved in the manufacture and design of accessories for underwater photography.

Later, in 2009, the company began to make a name for itself on the international scene thanks to its participation in international diving events and obtained the distribution of the prestigious Nauticam brand for Spain and Portugal.

Since then he has continued his work at SAGA, while combining it with his great passions: Underwater photography and travel.
