We are still amazed that after such a brief trip to Muskoka you found us the perfect retirement package. And to think we live in Beijing China - you served us professionally and never pressured a sale but knew what we wanted. And we found it and did the transaction remotely with your help. As returning Canadians we are grateful and please drop by this summer for visits.

My wife and I have bought a home and sold thru JACK. Professional and ethical would best describe Mr. Janssen. He looks out for his customers and nothing gets missed in his transactions. I highly recommend JACK and he is a TRUE MUSKOKA expert.
