Co-Chief of Staff Dr. Brian Nelson is a 1978 graduate of Iowa State University College of Veterinary Medicine. He grew up in central Iowa and moved to Wisconsin after graduation. Dr. Nelson began working at West Allis Animal Hospital in August 1978 working for Dr. W. G. Schwalbe and ended up buying the practice from him. He has special veterinary interests in general medicine, soft tissue surgery, laser surgery, and ferret medicine and surgery.

Dr. Nelson met his wife Karen in West Allis and they have three grown sons, two dogs, and one cat. In his spare time he enjoys golf, racquetball, music, movies, and spending time with family and friends. After almost 40 years of practice there are still things he hasn’t seen yet and that keeps him interested!

Dr. Shari Severson, our Co-Chief of Staff, graduated from the University of WI School of Veterinary Medicine in May of 1988. She spent one year in Akron, Ohio, specializing in Small Animal Medicine and Surgery. She has been at the West Allis Animal Hospital since August of 1990 and has a special interest in internal medicine and dermatology, but enjoys surgery as well.

She has three children and two furry beasts at home, golden retrievers, who are more spoiled than her kids, if possible. She also has one bunny. Out of the office, she likes to read when time permits, garden, and bake different breads and rolls. However, she feels that most of her off time is spent running her kids from one of their events to another. Two of her children are teenagers. Need we say more?!

In 2007 Dr. Selbert relocated with her husband, a Presbyterian minister, to O’Fallon, Illinois who began working with a church development near Scott Air Force Base. She became a principal veterinarian for the Troy Hawthorne Animal Clinic, participating in emergency care responsibilities with their 24-hour emergency and referral practice in Glen Carbon, Illinois. She also established the first dog park in Troy and offered dog agility classes there as well.
