Meet Our Veterinary Team

  • Elsa Swenson

    Dr. Elsa Swenson earned her Doctorate of Veterinary Medicine from Iowa State College of Veterinary Medicine in 2007 following completion of her Bachelors in Science degree at the University of Minnesota in 2003. Upon vet school graduation, she came to Tucson for an internship in emergency and general medicine which included some exotic pet medicine. Her interests include surgery, preventative medicine, pocket pet medicine (rabbits, guinea pigs, and other ‘small furries’), and preventative medicine. She is a member of the National Veterinary Response Team (NVRT) and is ready to deploy for veterinary needs if a national disaster occurs. When she isn’t at the clinic, Dr. Swenson enjoys hiking and traveling with her husband and daughter and spending time with her dog, Levi, four cats, and two chinchillas as well as playing in the local soccer rec leagues.

    Kate Clark
    Relief Veterinarian

    I was raised in Huber Heights, Ohio and graduated from The Ohio State University College of Veterinary Medicine in 1995. I started my career at Casa Grande Animal Hospital after graduation then moved to Oro Valley Pet Clinic in 1997. I have been helping Ajo Veterinary Clinic and other Tucson clinics as a relief veterinarian since 1999. I enjoy working with this staff, clients and special pets that we get the privilege to see at this clinic. I have spent some time as an adjunct professor at Pima Community College teaching in the Veterinary Technology Program. It was a wonderful experience working with the future technicians that will be helping our profession.

    In the hours not spent at clinics practicing medicine, I enjoy quilting. I have made over 350 quilts. Some have been shown at the Arizona Quilters Guild show in Phoenix. No ribbons have been won yet, but I keep striving to improve my technique. I have donated some of my quilts for raffles as fundraisers for local charities. The joy on the face of someone receiving this kind of hug is worth all the time I put into the quilt. My husband and 2 cats patiently wait on dinner while I finish “just one more seam”!

  • Dr.
    Penelope A. Porter

    I grew up in Central Iowa and graduated from Iowa State University in 1969. I was one of the first six women to graduate in Veterinary Medicine from Iowa State. The world has changed a great deal since then.

    I moved to Tucson, Arizona, to take a job at Valley Animal Hospital where I worked for two years then bought a small practice in Green Valley, Arizona. In 1973 I opened Ajo Veterinary Clinic at its current location. The Southwest side of Tucson has been very kind to my business and me over the past 38 years. I enjoy the challenges of the varied cultures and cases.

    I have two dogs of my own, 2 shepherds. I have a passion for old houses and live in a historic home in downtown Tucson.

Client Service Team

  • Sara Martinez
    Clinical Director

    I was born in San Diego, CA, and moved to Tucson when I was 11 years old. I am a 2001 graduate of the Pima Medical Institutes veterinary assistant program. I began working for Ajo Veterinary Clinic in 2001. In 2006 I earned my national and state certification as a Veterinary Technician. I enjoy the challenges and rewards of helping our clients keep the furry members of their families healthy. I have a weakness for older dogs and orange cats. When not reading or spending time with my family, I enjoy Tucson’s diverse music scene. More recently I have returned to school to study business to become a more successful practice manager.
