I don't know the top three but I know that Becky Ivins' Movers Real Estate has been #1 several times. They are a terrific firm to work with - smart, smart people there.
@Nathan Walker - What type of activity are you asking about? Total units? Number of agents? Units per agent? Something else?
Becky Ivans is #1 for sure, according to the person she pays to say that. She's paid Dave Ramsey to say she's number one and that must make it true!
But in terms of total volume, you're probably going to see The Levinson Team at the top of any list you look at, except for Vernon M., who always snags the top spot of total volume because his building company runs every build they church out through his MLS profile. #worksmarternotharder
But . . . if you have specific aspects to that question I bet Zach and I can help you out, as two excellent agents in the metro.
Boy that's a question that will get a thousand different answers. Do you currently have your RE license or are you in the process of getting it? If so you can go around and interview the brokers at all the different firms. That's what I did until I found the one that fit me the best. I'm at Metro First Realty of Edmond and love it. There are plenty of great firms (most are great) but you will have to find the one you like the most.
You should call my buddy at Foundation Insurance and Risk Management.
He is an independent agent and can quote properties with many different companies. This has given us a lot of freedom with finding the best coverages and the best prices. Not only is he is one of my best friends he is also an investor so he knows what he is doing. I dont worry about insurance at all anymore and he has handled a few claims for us that have gone smoothly. PM me for his details.
