 Growing up in Memphis, Tennessee, Mike was always surrounded by canine family members, especially German shepherds. His family also kept several cats, who likely kept a close eye on the wild animals that periodically visited the family’s backyard.

 Mike came to Brook-Falls Veterinary Hospital & Exotic Care with lots of business management experience under his belt. He enjoys working in an informal office environment, and appreciates the chance to meet clients and their pets.

 When Mike leaves for the day, he returns to his Oconomowoc home, which he shares with his wife and two dogs. He enjoys spending time with his children, who live within easy driving distance. With hobbies that include bowling and golf, Mike maintains an active lifestyle. In fact, Mike was once recognized for his golfing skills, finishing fourth in the Tennessee State Amateur Golf Tournament.

Now she has served pets and their families as a Certified Veterinary Technician for over a decade.

Holly grew up in West Allis. During high school, she volunteered at a cat clinic and spent a lot of time at her uncle’s farm. She attended Madison Area Technical College’s Veterinary Technician program to become certified and has worked with Drs. Follett and Bloss for 10 years.
