In 2009 I graduated from DePaul University with a degree in Real Estate Finance & Investment. Shortly after graduation I obtained my Real Estate license and went to work for a Real Estate Investment Firm. While working here I helped buy and sell over 6 million dollars of Residential Real Estate. Residential Sales has always been my passion, so in 2011 I decided to make it my full time job.

In 2012 I sold 107 homes, and 12.1 million dollars in Real Estate, putting me in the top 20 grossing Baird & Warner agents company wide. I also won the "Baird & Warner Rookie Of The Year" award. I have increased my volume every year I have been at Baird & Warner and have continually been one of the company's top producers.

I pride myself on exceptional service and a vast knowledge of multiple markets. I have sold homes from the far Western Suburbs to Chicago and everywhere in between. I am a life long Naperville resident and I have an extensive knowledge of the local market.

I have a unique blend of Real Estate experience. Whether it be first time purchases, income properties, foreclosures, luxury properties, or short sales, I have done it all and I am eager to share my expertise with my clients.

"Keith was great to work with and made our first home buying experience very positive. Not only was Keith knowledgeable about the areas where we were looking, he was also able to provide insight into the mortgage and closing process. He has great references for home buying ranging from a mortgage broker to home improvement professionals. If Keith could not answer a question, he quickly researched to find the answer. Lastly, Keith was helpful and honest and able to point out questions that we should ask and look out for. I would highly recommend selecting Keith as your realtor and would absolutely work with him again."

"Keith represented us as buyers for our new home in Aurora. It was our first time purchasing a home and Keith was very informative and knowledgeable of the buying process. He was very accommodating with our schedule and made sure the process went at a pace we were comfortable with. He also knew the area extremely well. I highly recommend Keith!"

"Keith was great to work with, and we are happy we chose him to sell our house. Throughout the process he was extremely responsive. I almost always got a hold of him the first time I tried, and if I didn't, I would hear back immediately. He was also extraordinarily patient. We had many questions along the way, and he was always happy to answer all of them and never made it feel like we were bothering him. He also paid attention to all the little details, such as bringing over an amazing photographer, a staging consultant, etc. I'd definitely recommend Keith."

"We found Keith as he listed a house we thought we had interest in. We ended up not liking the house and decided to hold off on purchasing/buying for a year. We kept in contact with Keith throughout the year and was very impressed with his knowledge of the market.

When we were ready to move we worked with Keith to sell our home and purchase a new one. The process was extremely easy to list our house and it went under contract in a matter of days. There were no surprises and Keith kept us very informed throughout the entire process. He was always very responsive and got back to us within minutes no matter what time of day it was. We felt like we were his only client (which was not the case).

We love our new home and neighborhood!! We highly recommend Keith to anyone in the market looking to buy or sell!!!"
