  • Sonja Lapinski, DVM

    Dr. Sonja Lapinski was born and raised in Portland, Oregon. She studied biology at Whitman College in Walla Walla, Washington, and veterinary medicine at Oregon State University’s College of Veterinary Medicine. She picked up commercial salmon fishing in Alaska as a summer job along the way and continued it through veterinary school.

    After an internship in Tucson, Arizona, Dr. Sonja returned to the Willamette Valley and has worked in Emergency Medicine and General Practice around the Portland metro area for the past 5 years.

    Dr. Sonja and her husband, Alex (also an Oregon native, from Corvallis), moved to Newberg in 2015 with their two small black mutts. They spend their free time adventuring around Oregon, or just enjoying the many perks of living in one of the world’s most beautiful and productive valleys. Dr. Sonja says she is very grateful to be joining such a highly-regarded, team-oriented and smart group at Carlton Veterinary Hospital.

Rachel and her husband are being raised by two boys: Oliver born 2014 and Emmett born 2016. Dr. Rachel is from Central Oregon and therefore loves being outdoors hiking, rafting and riding dirt bikes with her boys. Rachel's husband was born and raised in Yamhill and they are happy to be back home with their extended family.

  • Lucy
