Doctors & Staff

Dr. Mike Nelson, DVM

Dr. Mike Nelson, DVM, is the veterinarian and owner of Mahoning Valley Animal Hospital. Dr. Nelson will help educate you in all things animal related, be the doctor performing surgical procedures, will help you make decisions when it comes to the health of your pet, and ensure the highest standard of care during all of your pet’s life stages.
Dr. Nelson obtained his degree in veterinary medicine from the University of Wisconsin in 2003. He is always continuing his education by going to seminars and researching the latest products, medications, and surgical techniques. He does not have a specific favorite breed, as he is a lover of all animals both great and small. Dr. Nelson wanted to become a veterinarian not just because of his love for animals but for the science behind it as well.
Dr. Nelson has been married to his best friend, Kristen, since 1996. Together they have six children; Dani, Joe, Sam, David, Maddie, and Abby. He enjoys spending time with his wife and children. He is very active in his church and with the boy scouts. In his spare time Dr. Nelson is an avid cyclist, woodworker, and loves raising snakes and other reptiles.
Dr. Nelson’s pets include two chocolate labs named Teancum and Emma, a tortoise named Tank, and several snakes who don’t really have a name.
At Mahoning Valley Animal Hospital you may initially come through the doors as clients but you leave as family. That is the kind of care and compassion that drives Dr. Nelson and the staff at MVAH.
