Dr. Gregory Ogi, DVM

Dr. Ogi is a 1982 graduate of the University of Minnesota. Following graduation, he and his wife (Julie) moved back home to Kewaskum, where he joined his father in practice. Dr. Ogi bought the practice from his father (Dr. Charles Ogi, DVM) and is currently one of the owners of the Kewaskum Veterinary Clinic. Dr. Ogi and his wife Julie live just outside of Kewaskum on a small hobby farm. They have raised 7 children and now have 11 grandchildren. In his spare time, Dr. Ogi raises organically fed Black Angus cattle, chickens, and ducks. He also has 4 wonderful dogs (Georgie, Pokey, Buttons, and Maddie). On most days, Dr. Ogi can be found riding his Harley or driving his 1929 Model A Ford Coupe on his way into work.

Dr. Nicolas Wagner, Veterinarian

Dr. Nicholas Wagner, DVM graduated from Iowa State College of Veterinary Medicine in 2004 and quickly found a passion for small and large animal medicine. After many successful years of practicing both, he made the decision to solely focus on companion animals with a special interest in orthopedic surgery. Dr. Wagner is one of the owners of the Kewaskum Veterinary Clinic and takes pride in knowing his clinic's sole purpose is to provide quality, progressive, and compassionate care to all patients entrusted to us. When Dr. Wagner has a moment of "free time" he happily spends it expanding his knowledge with the help of the Science Channel, hiking in the Kettle Moraine, or relaxing on his pontoon with is wife of seven years, Chelsea, Pepper Ray and soon to be expected little girl. The Wagner family continues at home with an assortment of animals including Bailey, a 15 year old Labrador mix, Gertie, a 7 year old Terrier Mix, Gretta a 8 month old yorkie and three perfectly behaved cats: Peanut, Geppetto, and Hildie.
