I have bought and sold many houses, but Karen is by far the best agent I have ever had. Easy to get in touch with, responds to every question immediately, seems to work 24 hours a day. I have used her not only for purchases, but also for listing rental property. Goes above and beyond what any ordinary realtor would do. Highly recommend Karen. Six stars!

Karen was very helpful with the selling of our parent’s home. She answered all our questions and patiently guided us throughout the sale. She was great throughout the process

Karen is wonderful. I cannot say enough about her. As an out-of-state Buyer, we needed local expertise. Karen was fully familiar with all relocation processes and guided us every step of the way. Karen is dedicated and committed to her clients. A true professional! *Thank you Karen*

I am from Chicago and am new to New Orleans. I knew I was out of my comfort zone but had no idea how much I didn't know. Karen held my hand through the entire purchase. Karen found a great home inspection service which found several items that needed to be fixed before we purchased the house. Karen found me an house insurance agent, gave me the number of NOLA water and electric. Got me a home warranty to protect me in the future. She thought of everything before me and things I didn't even know to think of. Karen will help you make good financial decision and find the home you want.

We had the opportunity to work with Karen in our last move, and she is very professional. She goes above and beyond of the expectations that you might have from a Real State Agent, she is customer focus and she drives for excellence. She represented our interests in a way that I have not seen before, and she was supporting us even after closing our property. We hope we can find a Karen every time we move, she is definitely a jewel to keep and someone that you can count on in your journey. Thank you Karen for all your support, you made our experience easier!

Karen is great! She has helped me 3 times now with buying or selling a home. She goes an extra mile and makes the entire home buying or selling process easy. I'll work with her when I make my next move.

Karen has taken care of the buying and selling of all of my family and recently my best friend’s homes for 9 years now. Recently we bought our second home and selling our first home with Karen I could never go threw this with anyone else... I recently told her she can never retire cause I don’t trust anyone to take care of me like she does! She thinks of everything and takes care of it all!!! We love and appreciate you Karen so much💋❤️

Never having met Karen she worked on our behalf from 1600 miles away to find the home my wife and I could settle into in retirement. As a native of Louisiana I wanted my retirement years to be a time to reconnect with my roots. Karen diligently worked often after hours to ensure our needs were met. Through all the challenges Karen assured me she "Had My Back" and she Did. I am so happy to have allowed Karen to steer the ship to our safe harbor in our new home in Louisiana. With tremendous gratitude! John and Candy

Karen was the first person we called when we wanted sell our beloved home in Mandeville. With Karen’s care and insight she built a community of invested partners and made the process simple and easy for us to price and sell. Within five days, three business days we accepting a contract at 99% of asking price. Karen was strategic and had our best intentions at hear and mind going above and beyond for us at every step. When the professional opportunities call us back to the NOLA area we will call on Karen again as she is our agent for the region. Thank you Karen!

Karen is simply awesome. She is very informative and brings a wealth of experience and knowledge to navigating a sometimes complex process. She also shows a lot of empathy and compassion for those of us in tough situations. I really felt she was on my side and had my best interest in mind throughout the process. I have used Karen multiple times and always a positive experience.
