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.

"We are new to the state and Keith was recommended from a client, couldn't ask for a better real estate agent!! Keith walked us through every single detail about state laws and guidelines we knew nothing about considering the laws are different in every state. He is a very knowledgeable agent and it's a plus because he's from the area! Keith was accessible 24/7 and that was huge for us because we lived at a different state and traveled back and forth at the time! We knew we were in good hands! He was very patient with us throughout the whole process! I highly recommend Keith and my husband and I would give him a 10 out of 10!! Thank you Keith for helping us purchase our beautiful home!!"

"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."
