I came to the McHenry area in 1992, intending to stay just two years.  I liked the people and pets so much, I'm still here!  I live in the area with my wife, four children, and house full of furry friends. We really enjoy fishing, hiking and biking.  I look forward to helping you care for your furry friends.
