Ron Tenney, D.V.M. – Oasis founder in 1982

Ron Tenney, DVM E-mail: rtenney@oasisanimalclinic.com I am the founder of Oasis Animal Clinic. I am a native of Arizona, growing up in Prescott. I grew up on a ranch and spent many hours as a kid riding horses and doing chores. I realized at a young age that animals serve many purposes and play a big role in our lives. I decided to become a veterinarian expecting to move back to a small town and join a mixed animal practice (large and small animals). While attending Arizona State University, I began working in some local veterinary clinics and discovered a fascination with small animal medicine and surgery. I was drawn to the client-pet bond and the awesome opportunity veterinarians have to affect the quality of life of pets and their owners. I knew then that this was the area of veterinary medicine that I wanted to pursue. I attended Washington State University graduating in 1982.

Returning to Arizona, I opened Oasis Animal Clinic in December, 1982. In 1991, we moved from our original location on Dobson and Elliot Roads to the Wal-Mart PetSmart center in the corner of Alma School and Warner Roads. The practice grew during the twenty years we were located there. Eventually, we outgrew the 2,500 sq. ft. facility and began looking for a new place to call home. In October, 2011 we closed our doors at the old location leaving a million memories behind. We are now in our new facility on the Southeast corner or Ray and McQueen Roads. It is hard to believe that we have been in our new building for the past five years. We are thrilled to be in a 5,200 square foot facility with all of the convenience and space to offer state of the art care. My professional interests include advanced training in pain management and best practice anesthetic protocols. For six years between 2006 and 2012, I had the opportunity to visit local veterinary hospitals teaching about modern methods of safe anesthesia and recovery with the Zoetis Animal Health DALE program. I learned from each practice that I visited. 

Watching this practice grow and develop is really amazing. I am very grateful to have such an awesome team of doctors and staff to provide care to so many patients and their owners. We have come a long way in the past 34 years!

On the personal side, I am married to Marilyn Richardson Tenney and together we have 5 sons. Marilyn is a Licensed Professional Counselor specializing in Marriage, Family and Addiction as well as healing from trauma. We live in Gilbert, where we have a terrier mix named Pancho Villa. We recently lost our 17 year old cat, Don Juan and our 16 year old Jack Russell, Jamie. Everyone in my family love pets.

Over the years, many of you have met our sons working around the clinic. Currently, Brandon  is studying sound engineering and working for a local video production company (the same company that created some of our clinic online videos).  The next oldest is Trevor. He graduated from ASU and then completed his veterinary training at Texas A&M’s College of Veterinary Medicine where he graduated in the Spring of 2016 with his Doctor of Veterinary Medicine degree. Trevor was selected to become a member of the United States Army Veterinary Corp where he is serve for at least the first four years after graduation. He is currently stationed in Japan on the Yokosuka Naval Base. Troy is married (Maize) and he is the father of our youngest grandchild, Ira. He is enrolled in medical school  (human – not veterinary) at MidWestern University in Glendale Arizona. He is interested to pursuing a career in Pathology. Gary is the second oldest of our sons and is a PhD psychologist. He opened his own private psychological practice in Gilbert, AZ.  He is married to Angela Tenney of Tempe and they have a son, Dillon and a daughter, Audrey. Our oldest son, Rhett is married to Sandee Tenney and they are living in Eagar, AZ where both he and Sandee are teachers at Round Valley High School.  They have 2 daughters, Josie and Sophie,  and a son, Sam. Their family is very active in sports and other extra-curricular activities.

My interests and hobbies include scuba diving, playing racquetball, video editing and computers. Don’t ask to see any of my underwater videos (or here – Red Sea 2014) unless you have some time on your hands. I also enjoy reading (especially history) and volunteering time for our church and other organizations. All of our family members are certified scuba divers and we love to travel and dive as a family. We have been able to see many beautiful areas and create vivid memories thanks to this sport. Thank you for your loyalty and support of Oasis Animal Hospital. We are humbled to be able to care for your pets.

I recently wrote an article about the joys of veterinary medicine from my perspective.

Mary Knott, D.V.M.

Dr. Mary Knott joined the Oasis team in February 2012.  Born and raised in Council Bluffs, Iowa, Dr. Knott attended Iowa State University for undergraduate and veterinary school.  Her family says that she decided to become a veterinarian when she was about 6 years old.  She graduated in 2000 with her doctorate of veterinary medicine.  Following graduation she spent a year in an internship at a small animal referral and emergency hospital in California and another year in an internal medicine internship at a referral hospital in Florida to gain vital experience in critical care and internal medicine. After her internships Dr. Knott moved to Champaign, Illinois, where she worked at an emergency hospital.  She enjoyed the fast pace of emergency medicine and the challenging cases, but when she met her husband she decided it was time to work “normal” hours.  When they moved to Arizona in 2005 she made the switch to general practice.  The best part about general practice she says, is being able to build relationships with clients and manage patients over the long haul. Outside of work, Dr. Knott is active in the local running and triathlon community.  She loves running marathons, and has been fortunate to run the Boston Marathon twice and recently competed in the Kona Ironman competition.  She enjoys racing Ironman triathlons and qualified in her 19th Ironman to compete at the World Championships in Hawaii.  Her husband, Dan, has been involved in the retail running shoe industry for over 15 years and together they opened Cadence Running Company in Gilbert at the start of 2013.
