My family enjoyed Mallory's perfect balance of patience and persistence and would recommend her to anyone looking to buy or sell!

We first met Pat and Mallory O’Brien when they represented the seller of a home we purchased years ago. Even as dual agents, I have never felt more represented or trusted an agent more. This was the 10th home we’ve bought, and they are by far the best real estate professionals we’ve ever worked with. They operate as a seamless team, advocating fiercely for their clients while handling countless details behind the scenes and making the process feel easy. Most recently, they helped us find and secure our dream home—something that would not have happened without them. Their honesty, loyalty, and integrity truly set them apart. Buying a home is emotional, and Pat and Mallory guided us through every step with care and clarity. We can’t recommend them enough.

After another 4th of July with too many kids, grandkids, nieces, nephews and dogs my wife decided that we absolutely needed our own place. Mallory and Pat did more than just stick us on an email list. They showed us houses in Charlevoix, Petoskey and Boyne City and kept us informed about any changes in the markets.
Because of their deep ties to their towns we were able to see the place we ended up buying a day or two before it was actually listed. Even after we bought the house Mallory was so helpful with the closing and getting utilities settled.
Their honesty and integrity is beyond reproach and they never forget that they are working for you.
Please consider the O’Briens for any of your real estate needs.
