I am a dedicated father of three; a 24 year real estate veteran, born and raised in Southeastern Wisconsin. Prior to my real estate career, I graduated from the University of Wisconsin-Milwaukee with a degree in Marketing. For 11 years I worked for two Fortune 50 Companies; Pepsi Cola-USA and GE Healthcare. My corporate experience combined with my investment property know-how has led me to become a Top Producing Realtor in the Metropolitan area for the past 17 years. I have consistently received numerous honors and awards: The Five Star Best in Client Satisfaction award (10 consecutive years) as well as achieving the status of Associate Vice-President at Shorewest. I pride myself on my listening skills, negotiating talents, customer service dedication, passion for people, market knowledge and my endless energy.

Gary Weber

I have been a full time Realtor with Shorewest Realtors since 2002. Besides a wealth of real estate market knowledge and experience, I work diligently with my clients always keeping their best interests in mind to help them achieve their desired goals, whether buying or selling a home. I have been awarded the prestigious Five Star Best in Client Satisfaction award, by Milwaukee Magazine for 10 consecutive years. This award has been given annually since 2008 to just the top 5% of Realtors in our marketplace who achieve the highest rating in a survey of recent homeowners. In 2012, I was named an Associate Vice President of Shorewest Realtors in recognition of my career accomplishments and honors. I am a lifelong Wisconsin resident, residing mostly in Brookfield and Delafield. My wife Susan, also a licensed Realtor and I own a vacation home in Scottsdale AZ, where I also hold an active real estate license to assist clients who decide to follow the warmth to sunny Arizona.
