    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.

    I'm originally from the Rockford area and moved to the McHenry area after graduating from veterinary school.  My husband and I are involved in training, showing and breeding of German line German Shepherd Dogs, and are privileged to co-own a national champion, the 2010 UScA Siegeren.  My current dog sport passion is Schutzhund, but I have competed in and taught obedience, tracking and agility in the past.  Other hobbies include hiking, reading, and computers.

    After graduating from The Ohio State University College of Veterinary Medicine in 1988 I practiced in central Ohio on both large and small animals.  In 2011 I moved to this area with my wife, three boys, and our dog Boots.  We enjoy the welcoming people and safe environment here.  In our free time we enjoy watching our boys compete in their favorite sports, gardening, hiking and other outdoor activities.
