Testimonials

Working with Mara has been a wonderful experience. Her patience, communication and attention to detail is beyond what we could have imaged and even during this (crazy) time with the housing market, Mara was always supportive in the decisions we were making or needed help making along the way.

Lesley Goddard

We are really happy to be working with Mara Ondejko. We were first time buyers and were quite green to the process. Mara assisted and guided us in every process on the way and supported us to make our dream come true. She was very responsive & dedicated, and we are really thankful to all her efforts.

Melvin Thomas

I was a first time home buyer with no experience in the real estate market. Mara directed me through the whole process and made it a very pleasant and enjoyable experience!

Josh C

As first time home buyers we didn't really know what we were doing nor had the time to do what needed to be done. Mara Ondejko offered to help and within months we got a home. She went above and beyond to help make the process as easy as possible.

Maria Bueckert

We cannot thank you enough of all the caring and support you have given us. You are now a new member of our Family. Thank you again.

Lopatin Family

Mara is amazing! She was knowledgeable and helpful throughout the process of buying my home. It is obvious that she cares about her clients, and wants to make sure that they find the right fit from them. Highly recommend her to anyone else looking to buy or sell!
