Meet the Team

Dr. Doug Johannessen graduated from Ross University School of Veterinary Medicine in 2006 after first receiving his masters in Animal Physiology and Immunology in 2001. He practiced in California and Montana following vet school until purchasing Westside Animal Hospital in Casper, WY in 2011. For the last 10 years, Doug and his wife Laura, have been co-owners and have together developed their hospital into a top-notch family-oriented practice all while raising 3 daughters. In 2022 they became Hound and Katt Veterinarian and moved locations to provide later evening hours and walk-in urgent care appointments.  

Dr. Doug's professional interests include surgery, dentistry, and urgent care. He works closely with the traveling surgeon Dr. Jayce Lineberger with Ace Mobile Veterinary Surgery when he travels to Casper for orthopedic and specialty surgery cases.

In 2012, along with her husband, purchased Westside Animal Hospital and moved to Casper, WY. For the last 10 years they have been co-owners and have together developed WAH into a top-notch family-oriented practice all while raising 3 daughters.

Devon Hendrickson joined our Hound & Katt Veterinarian team in December 2019. She moved to Casper from Price, UT, but has spent a lot of time growing up in southwest Wyoming. She studied Veterinary Technology through San Juan College from 2019 to 2022. Devon's role at Hound & Katt is senior technician and office manager, where she oversees surgical procedures and also keeps busy with teaching and training other new veterinary assistants. 

Catie joined our team in March of 2025 as a vet assistant, but she is currently enrolled in Penn Foster to get her Veterinary Techinican degree. She has wanted to work with animals for as long as she can rememeber. You will find her either upfront, greeting clients, answering phones and scheduling appointments or you will see her helping the techinicians and veterinarians. 

Catie has lived in Wyoming for 4 years. Catie has 2 dogs; an Australian Shepherd names Josie Mae and a Corgi named Winnie. In her free time Catie enjoys being outdoors, especially at the lake or reading. 

Abby started with Hound and Katt in July 2025. She is our receptionist, so you will find her answering phones, checking our clients in and out, and rooming our patients. When she is not doing that, she is helping our veterinarian or our veterinarian technicians. She is planning to pursue her Veterinary Techinican Degree in the near future. She loves animals and is enjoying all of the patients we see. 

In her free time she is spending time with her three dogs Remi (a brittney spaniel), Bonnie (a red heeler), and Charlie (a german shorthair pointer), or she is spending time with her family or going on walks!
