Mary has had her real estate license since 2000.  However, her entire family is in real estate and she grew up having family dinner conversations all about real estate as her entire family works in the industry.  Suffice it to say; residential real estate is in Mary's blood! 

Mary began her career in real estate while she was a trader on the floor of the Chicago Mercantile Exchange (CME).  With the call letters of OHNO, Mary made her living and earned a great reputation as a quick-thinking, fact-based professional with an amazing memory for details.  Mary's memory has served her clients very well as she can recall minute details of properties; numbers, floor plans, property stability/reputation, availability, listing prices, you name it!  She knows the real estate market.  One client stated that "..Mary would win the Chicago Area Real Estate Trivia Championship, if there were one.." 

In 2004, Mary left the CME and started focusing exclusively on residential real estate.  Mary has since closed more than 300 deals worth over $175Million, ranging from property worth 60K to 4.2M making her one of the most experienced in her field.  Mary represents all types of clients - from first time homebuyers to downsizing empty nesters to seasoned investors.  Mary connects with her clients very effectively and is able to present real options to her client and help them streamline their search.  At the same time, she  will gladly show a client numerous homes to help clients focus in on their needs.  Mary will dig deeper than any other agent will to find the right home.  "¦ Mary knew what I wanted before I did¦" quotes a satisfied client. 

Using data-analytics, Mary will help determine market value whether you are buying or selling.  Tracking trends in the market, neighborhood news, developer plans, broker sentiment, housing market indices, interest rates and mortgage news is a standard offering of Mary's client centric service.  Mary possesses savvy negotiation skills and can passionately defend or dispute an appraisal or pricing to achieve optimal results.  Mary zealously protects her clients and their interests: she has your back and will not disappoint. 

A happy client states  "Mary will go above and beyond; wow she was helpful!..."  Whether a client wants to see hundreds of properties, feels better with a detailed explanation of every step, or is interested in knowing the contract cold, Mary delivers.  If a client wants contractor, inspector, builder, financing or a mortgage, Mary will help with a referral.  Mary is authentic; she will not hold back in telling you the faults of a property.  When you buy with Mary, she will tell you the same issues a property has that she would tell you when you go to sell it.  Her integrity is unquestionable. 


Almost all of her business is from past clients or friends of past clients who have been pleased with the attention and care she gave them when helping them buy or sell a home. She is  very hard-working and genuine. And she believes the best way to run her business is to take care of people the way she would want people to take care of her.

Mary relentlessly pursues excellence on your behalf. Mary recognizes that home buying or selling is one of the most important financial transactions of your lifetime.  She will not stop until her clients are thrilled.
