I work with all types of home buyers, sellers and investors--from custom new homes to mid-sized ranch or energy-efficient green home renovations.

Denver Metro is a beautiful place to live. There are many different neighborhoods to choose from and a variety of green home price ranges to meet most any budget.

If you are relocating to the area, I can help you find a green home that best meets your needs in proximity to work, schools and shopping. And no matter where you drive around Denver you'll enjoy expansive views of the Colorado Rocky Mountains. And it's easy to get around in Denver. The highway system including I-25, I-70 and I-225 all link to form a ring around the heart of the city.

What can I say about Boulder except it is a haven nestled at the foot of the Flatiron range set apart from Denver in a world of its own. Boulder has it all and is a great place to live, work and play. Of course, there are many nice places to live in Denver Metro. It is really a matter of finding a green home and location that best suits your needs.

I have developed a specialty in the area of green homes. I have the EcoBroker Certification and I am currently working on the LEED for Homes certification. I can help you find a green home that is healthier, more comfortable and has a lower operating costs compared to similar size homes that are not designed green.

I am happy to serve all of Denver Metro and Boulder County including Arvada, Wheat Ridge, Boulder, Superior, Louisville, Longmount, Northglenn, Thornton, Westminster, Commerce City, Aurora, Denver, Lakewood, Littleton, and Parker.

I can provide you with the latest market statistics showing price trends over change including what areas are showing the strongest appreciation. For investors, I have information showing where the up and coming markets are located in addition to the new Denver ligh rail which is planned. I can also provide you with area maps showing the average price ranges and percent foreclosures broken down by neighborhood.

What ever your home buying or selling needs may be, I have the tools, resources, training, education and experience to help you make the best, most informed decision possible.
