Dr. Dawn Evert completed a Bachelor of Science and a Master of Science degree in Biology at Central Washington University, then went on to complete her Doctorate of Veterinary Medicine at Washington State University in 2007.  After graduation, Dr. Evert worked as an associate veterinarian at a mixed animal practice in Ellensburg, WA.  In her spare time she did relief work for a veterinary emergency hospital in Yakima, WA, taught Biology at Central Washington University, and was an advisor for the pre-veterinary club at CWU. 

In 2009, Dr. Evert and her husband, Andrew, moved to Vancouver, WA and she joined the Claus Paws team as an associate veterinarian.  She has continued her love of teaching and fostering work with pre-veterinary students and technician students as a mentor in the clinic.  She has a special interest in cardiology and soft tissue surgery.  In 2019, Dr. Evert became the medical director at Claus Paws, and will continue to lead the team into the future. 

In addition to veterinary medicine, Dr. Evert enjoys spending time with her husband (Andrew), three children (Katie, Jimmy, and Mikey), and cat (Oni).  She also helps teach karate at her husband’s karate school, Vancouver Shudokan Karate-do.  She currently holds the rank of San Dan (3rd degree black).

Dr. Karen Chan is originally from Seattle and received her bachelor's degree in biology from the University of Washington. She went on to Washington State University where she earned her Doctorate of Veterinary Medicine.

After veterinary school, she completed a rigorous one-year small animal rotating internship at Kansas State University where she received additional training in internal medicine, surgery, and emergency medicine. Having had enough of the cold weather, Dr. Chan moved back to the Pacific Northwest and relocated to Vancouver.

She has worked as an overnight emergency doctor and as an associate general practitioner for the past several years. Her professional interests include creating strong client/patient relationships within the community, preventative medicine, and geriatric care. Dr. Chan has three cats at home, including a tripod kitty. Outside of veterinary medicine, she and her husband love to travel and explore new cultures and food. She is also an avid rare houseplant collector and currently has a collection of over 100 plants.

Dr. Rachel has wanted to be a veterinarian since she was five. Her love of animals started with weekly trips to the Denver Zoo (Rachel is a Colorado Native) and then with her dogs, cat, gerbil, green anoles, horse and degus growing up. 

She was initially drawn to the Pacific Northwest to attend Washington State University, where she completed bachelor’s degrees in Neuroscience and Spanish. Rachel then moved back to Colorado to attend Colorado State University’s College of Veterinary Medicine and Biomedical Sciences. She has been back in the Pacific Northwest since graduating and has enjoyed getting involved with Washington State University's Elson S. Floyd College of Medicine by hosting medical students and teaching a comparative medicine class. 

In her free time, she enjoys cooking, skiing, crafting and exploring with her family.

Dr. Anthony Colandreo was born and raised in New Jersey. He graduated from Rutgers University with a bachelors degree in Animal Science, and discovered a love of veterinary medicine working as a technician’s assistant during the summers between classes. He graduated from the University of Pennsylvania School of Veterinary Medicine in 2013 and immediately went to work in a mixed animal practice in New Jersey.

One year later, after a scenic vacation to Oregon, he relocated to the Pacific Northwest and spent six years in small animal general practice. To better pursue his love of surgery, Dr. Colandreo joined the Claus Paws team in April 2021 as a dedicated associate who performs surgery. While he enjoys all aspects of surgery, he is particularly interested in gastrointestinal and ophthalmic procedures. In his free time, Dr. Colandreo enjoys jogging, reading, and spending time with his numerous pets - including one dog and five cats.

Osta Lundy has been with Claus Paws since 2013, where she started as a technician and receptionist. After 3 years, Osta became the lead technician of the hospital and then was promoted again to the Practice Manager position in 2017, which she has held ever since.

Osta started her education in pre-veterinary and also graduated from Veterinary Assistant school in 2010,but ultimately decided to pursue business and management positions instead.  Most recently, Osta went back to school and graduated with her Bachelors in Business Administration in 2021.

In her free time, Osta spends time with her family, her husband Shaun and their 3 pets (1 cat and 2 dogs).  She also enjoys reading, craft beer, and anything spooky.
