He was born in Madison, Wisconsin and moved to Milwaukee's East Side when he was two years old. He attended Nicolet High School and earned a bachelor's degree in biology from the University of Wisconsin-Madison. He then attended the University of Minnesota, Twin Cities, to study animal science.
During his free time, Dr. Arnold volunteered at wildlife preserves, cared for animals on display and shadowed local veterinarians during procedures. He also worked as a small-animal vet in Shorewood and Milwaukee.
In 2018, he was featured on TV news for playing songs on his guitar for animal patients at his clinic in Shorewood. He told WISN 12 he often played the song for his clients to relax and get them more comfortable before seeing him.
His clinic was at 4604 Wilson Drive in Shorewood.
A woman who previously worked at the clinic filed a lawsuit against Arnold last week in federal court. She claims he forced her into uncomfortable situations with his wife and multiple mistresses, including making lewd comments about her body.
She says he had no boundaries with her and repeatedly asked her questions about her sex life. He would also show her graphic sexual photos that his wife sent him, the lawsuit says.
She was fired in retaliation after she complained to the human resource manager about Arnold's treatment of her. The lawsuit also claims she was asked to help cover up his drug use and affairs.
