Who we are
How it all began...
I wonder that each and every day?!?!?
After 36 years as a practicing veterinarian, and 66 years of life, I decided to change paths and look for an opportunity to explore my many other interests mixing business and animal science. VOILA!! I reconnected with Dr. Ellen Dierenfeld, now my partner and friend, and truly- a world renowned animal nutritionist who is recognized as the ‘Mother of Zoo Animal Nutrition’. We have combined our 70+ years working with critters of all sizes, shapes and unique personalities and headed down the path to ZOOTRILOGICS!
My own training and work as a veterinarian, attending to elephants, dogs, cats, rabbits and-- lions, tigers and bears, OH MY!, has alerted me to the influence of good or bad husbandry in carrying for mother nature’s vast array of life forms. Husbandry refers to housing, health care and NUTRITION!! There ya go.
What we do
The facts are good or bad nutrition in humans and animal alike, is often the first expression of good or bad health. It may be as simple as an oily skin coat, obesity or a nasty poop that tells me that I need to look into that animal’s diet management. Veterinarians and nutritionists jump into ‘detective mode’ to discover what problems need to be addressed. Dr. Ellen and myself are those very detectives working to resolve diet and
nutrition management problems in zoos, private pet homes, sanctuaries, in the wild and in fact, anywhere our help is needed.
