Professional company! I’m on the board of our Condo Association and we had to find a new management company at the beginning of this year. We chose OTM and I have been very pleased so far. They are profesional, organized and responsive. They are really helping us correct the direction of our previous management company. It’s a big task and they’re doing it well. Thanks OTM!

On the Mark Management has taken over managing our condo complex, Gardens at Summerfield, and has done a fantastic job! When I called to be sure that we were up-to-date, the staff was not just professional but also friendly. The grounds have never looked so good, and Kevin keeps us all in the loop with detailed emails whether it be about scheduled meetings or happens around the neighborhood. I highly recommend On the Mark!

On the Mark is a reMARKable management company! The whole team over there is extremely professional, reliable and truly cares about people and the community. I utilized their Real Estate services to buy my first home! It was such a roller coaster, but Shelby was a pleasure to work with and navigated any and all situations and circumstances with ease. Would highly recommend for any and all management or real estate needs!
