What Our Customers Are Saying


I couldn’t thank Red Door Technologies and Tony Chan more for updating our IT infrastructure.  We have seen a drastic improvement in productivity and operations.  For a construction company that does millions in revenue, we were behind the curve when it came to technology and getting our operations ready for the future.  With the support of Red Door, we know we don’t have to worry about being behind in technology and can focus our efforts on what we do best in our business and serving our customers.  We truly see our partnership with Red Door as integral to our success for many years to come.  Thanks again!

Josh Burton
President, Legend Exteriors

I highly recommend Red Door Technologies and team.  They provided our business with the best IT support I’ve ever had.  Our business and team members are thrilled with the support and friendly service that is ALWAYS provided by Red Door and team.  We truly appreciate the hard work and dedication to seeing our business succeed and allowing our operations to be more streamlined and efficient.

Dee Parker
CEO, Parker Group

Red Door Technologies is truly a dedicated group of IT professionals.  We had a project we needed major help with and couldn’t find support as they provided.  Michael Dunfee was wonderful throughout the process of Discovery and allowed us to talk and get our frustrations but also allowed us to discuss our business goals and to see what can be provided from a technology standpoint to get us to where we needed to be in our industry.  So far, Red Door Technologies has delivered on every aspect as promised and we look to a mutually beneficial partnership for a very long time.
