About Dr. Harrison

Who is Dr. Greg Harrison?

Harrison’s Bird Foods were formulated in the mid-1980’s by Dr. Greg Harrison and HBD Intl., Inc. was established in 1989 to market theses new diets. But who is this guy and how did he get to know so much about feeding birds?

After growing up in a small farming community in Iowa, Greg Harrison attended Iowa State University (ISU) where he earned his Doctor of Veterinary Medicine (DVM) degree in 1967. He moved to South Florida where he worked in a small animal clinic and then opened his own practice in 1969 in Lake Worth. There he raised his family and gravitated toward aviculture after serving as a zoo and wild animal park consultant. He soon established The Bird Hospital, the first Florida practice exclusively developed for pet bird medicine and surgery.

At one time when the importation of parrots into the United States was still very popular, he owned 200 pairs of various species of psittacine birds. In a clinical trial to improve the breeding results of a group of hyacinth macaws, he developed a formulated diet, which became the basis for Harrison’s Bird Foods, the world’s first organic formulated pet food. Dr. Harrison continues as President of HBD Intl, Inc., the manufacturer of Harrison’s Bird Foods.

Through continued study, Dr. Harrison became a Diplomate of the American Board of Veterinary Practitioners (ABVP) and a Diplomate of the European College of Avian Medicine and Surgery (ECAMS), two avian veterinary specialty organizations. There are currently only seven other veterinarians in the United States and European Union who are double-boarded avian specialists.

In 1997, he was awarded the Stange Award, ISU’s highest honor for contributions to the veterinary field. Dr. Harrison is committed to sustainable agriculture and has been a member of the Board of Directors of the Rachel Carson Council since 2001.

When he retired from veterinary practice in January, 2005, he created Spix Publishing Inc, a small communications company. Spix Publishing has recently released a two-volume avian veterinary textbook, called Clinical Avian Medicine. Besides coordinating the efforts of 50 contributing authors along with his co-editor, Dr. Teresa Lightfoot, Dr. Harrison contributed to the writing of multiple chapters.
