About Me


My name is Dennis Quinn, I have Master of Arts degree in Ecology & Environmental Science from Central Connecticut State University and a bachelor’s degree in Biology with a concentration in Ecology, Evolution and Biodiversity.  My interest in reptiles and amphibians stems back to my early childhood days where I spent many hours observing reptiles and amphibians with my father in the field. In 2007, I founded CTHerpConsultant, LLC, now operating as Quinn Ecological, LLC to facilitate the pursuit and passion I have for reptile and amphibian research, conservation and preservation. Since then my company has provided a variety of ecological services ranging from general wildlife and habitat characterization surveys, to detailed environmental impact assessments complete with land use planning, mitigation design and monitoring for local, state and federal governments in addition to the private sector. I have worked directly with a variety of state and federally threatened and endangered species, including the bog turtle, eastern spadefoot and timber rattlesnake. I am active in environmental education through my Adjunct Instructor position at Naugatuck Valley Community College, where I teach General Zoology, Field Biology and Introductory Biology.


Early in my career I was very fortunate to have met two incredible herpetologist/conservation biologists, Hank Gruner and Dr. Michael Klemens, who have since mentored and guided me extensively and to whom I owe a great amount of gratitude and thanks for making this site possible.


Since this is a photographic atlas to the identification of CT’s amphibians and reptiles, you may be asking yourself if I enjoy photography and of course the answer is yes. I have been a nature photographer for many years and have recently begun sharing my images with the public.  All photographs are © Dennis Quinn Photography; permission for both educational use and publications will be granted with prior notification. Fine art prints are available at


Thanks for visiting Connecticut Herpetology, I hope you enjoy your experience and find this content useful in aiding the  identification process.
