My name is Todd Bollenbacher. I have been working in commercial real estate for the past 5 years. During that time I have worked on leasing, sales, and income producing property evaluations. Enjoying the hunt for deals, I look into and  beyond the numbers as each specific scenario is unique.  I am then able to recommend  appropriate value ranges for my clients based on their specific goals. And once the deal is in contract I work diligently to help ensure timelines are met and required information is exchanged keeping the deal on track to close.
