Ry Keller- Business Owner

I am a fourth generation Bigfork resident that graduated from Bigfork High School.  I went on to study housing and Urban development from Antioch College where I received my B.A. degree.  I started Valley Maintenance & Property Management in 1995 with my wife Serena.  We have two sons 18 and 21.  I’m a member of the Bigfork, Kalispell and Lakeside Chambers of Commerce.  I am registered as a general contractor and also have my Property Management License from the Montana State Realty Board and I’m an affiliate member of the Northwest Montana Association of Realtors.  I spent 10 years as a member of toastmasters reaching the level of Club President and also  am current president of the Experimental Aircraft Association Chapter 102.  I enjoy skiing, sailing and scuba diving with my family.

Shannon Bagley-Office Manager & Walter

I am a Licensed MT Property Manager at Valley Maintenance and handles most of the Long Term and Vacation rentals. With a degree in accounting, I’m the office manager and try my best to keep the office running smoothly and efficiently (good luck with that some days!).

I love Bigfork and have been in the Bigfork Area Chamber of Commerce Board of Directors for a combined total of 14 years. Serving as President for 3 years and currently as Treasurer. I’m also on the Bigfork Center for the Performing Arts Foundation Board of Directors, currently serving as Treasurer.

In my spare time I enjoy acting, CrossFit, traveling and a good glass of wine. My three children still keep me busy, although they are grown and out of the house. She loves them all dearly, but maybe Walter the best (don’t tell the kids!).


Walter is the official Greeter for Valley Maintenance. He sits on his little perch by the window and watches the cars come and go in the parking lot. He enjoys watching the birds too and the occasional deer. Walter is a 4-year-old Shi tzu with one blind eye, but that sure doesn’t slow him down. If you bring a treat when you come to the office, you might have a friend for life!

Frank –

I unequivocally recommend Ry Keller and Valley Maintenance to anyone looking for a property manager for a part time home.
