Dr. Randy Aronson has dedicated his professional life to providing innovative veterinary care for companion animals of Arizona. He is never satisfied with the status quo and is determined to provide the best care for his patients and the people who love them. Advancing preventative and diagnostic capabilities as well as enhancing treatment outcomes is his passion.
Dr. Aronson augments his over 35 years of traditional veterinary experience as both a practice owner and an accomplished practitioner through the completion and certification in complementary modalities. Dr. Aronson has extensive training in rehabilitation therapy, Chinese food therapy, Chinese herbal medicine, and acupuncture. His gift is seeing the big picture, embracing the concept of optimum health and accurate diagnoses, caring for the whole animal, not simply treating disease symptoms.
Inspired by the synergy of integrating conventional and complementary medicine, Dr. Randy Aronson and his wife, Dr. Geren Thurston, set out to create a new paradigm of care for companion animals of southern Arizona. PAWS Integrative Veterinary Center is his passion and shared vision for the future of veterinary medicine.
Dr. Aronson grew up in Philadelphia dreaming of becoming an equine veterinarian or a NBA star. He received his undergraduate degree from George Washington University. He went on to pursue his Veterinary Medical Degree from the University of Pennsylvania. He graduated in 1980 receiving the Leonard Pearson award, the highest honor of student achievement. He completed a combined small animal Internship in 1981.
When Dr. Aronson is not caring for animals and educating clients at PAWS, he is busy providing seminars, Skype conferences, Key note speaking, consulting for pet health product companies, providing consultations with pet owners through Google hangouts, and hosted a call-in talk radio show, Radio Pet Vet with Dr. Randy for over 10 years. He enjoys educating pet owners through both public speaking and column writing. He is a member of the National Speakers’ Association; he has published numerous articles in both national and local periodicals. To ensure quality and accountability for the safety and benefit of his patients, he directed and co-formulated 2Docs, a comprehensive line of vitamins and dietary supplements.
Although he loves biking, hiking, fishing, gardening, and reading, most of his free-time is spent goofing around with his son, Benjamin and daughter Livia.
Geren Thurston, DVM
Veterinarian & Practice Owner
For Dr. Geren Thurston, a passion and appreciation for animals combined with a love for science and problem solving shaped a childhood dream of becoming a Veterinarian. As soon as she had her driver’s license, she secured her dream job cleaning kennels and walking dogs at a Veterinary Clinic in Nebraska. Through this early experience, she was transformed by the profound human-animal bond, the magical connection of meaning and joy that we share with animals. Witnessing the important role medical care, disease prevention and education have in the lives of people and their beloved pets, resolved her to continue her pursuit of Veterinary Medicine. Sharing in, protecting and prolonging the relationships that we experience with animals is her enduring source of inspiration and fulfillment.
Dr. Geren Thurston fell in love with Tucson during her undergraduate education, earning a Bachelor of Science degree from the University of Arizona in 1997. She attended Veterinary School at Colorado State University in Fort Collins and received her D.V.M. degree in 2001. She was recognized through varied academic and service achievements.
Upon completion of Veterinary School in 2001, Dr. Geren Thurston eagerly returned to Tucson to begin her career caring for dogs and cats. She enjoys the challenges and rewards of general practice, from puppy and kitten exams to end of life care, as well as the preventative, surgical and medical services in between.
After many years of planning, Dr. Geren Thurston and her best friend & husband, Dr. Randy Aronson, opened PAWS in July of 2008. PAWS is the embodiment of their shared passion and vision for the future of Veterinary Medicine, as well as their commitment of caring for pets and people of Southern Arizona.
