About Doctor Door

Doctor Door Owner and Operator John Dalke knows garage doors.

After studying business management at Montana State University, John began working as a technician in the garage door industry. Since then, John has become a garage door expert with a particular interest in exceeding client expectations. He’s also learned a few things along the way, including:
+ Problems usually don’t occur when it’s convenient.
+ People outside of Bozeman have problems with their garage doors, too.
+ All commercial and residential garage door owners appreciate fast, quality, on-site service, clear communication, and good value.

To meet the demands of a growing Bozeman community, in January 2015, Doctor Door became a reality. Now John applies what he learned to his own business:
+ Be available outside regular business hours.
+ Travel across Southwest Montana to fix garage door problems.
+ Deliver same-day, efficient service at a competitive price.

Living in the Bozeman area since 1995 and stepping into the garage door industry in 2000 – John continues to exceed the needs of garage door owners in Bozeman, the surrounding Gallatin Valley area and beyond.
