  • "Janssen Animal Clinic has always been wonderful to Bagel, my almost 18 yr old Border Terrier. Dr. Janssen and his staff are courteous, professional, and treat Bagel with lots of TLC. Dr. Janssen is very thorough with his exams and always ready to listen to my questions and answer them in a manner that I can understand."
    Linda Barrett
  • "We have a 5 star rating from 99.1% of our clients!

    We've been bringing our pets to Janssen Clinic since 1998. Dr. Janssen and his team are the best. I never struggle trying to get in for an appointment & they are so kind and good with my pets. Dr. Janssen is very calm & caring. My dog is high strung & extremely attached to me. She calms down quickly in their office, however, because of their ability to soothe her. We wouldn't go anywhere else."
