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."
