I am a Berthoud, Colorado resident and have lived in the Front Range for over 45 years.  I was born and raised in Manitou Springs, attended college at Colorado State University in Fort Collins, then worked as an environmental consultant and professional geologist while living in the Longmont, Firestone, and Berthoud areas for over 25 years.  I am a family man and I enjoy spending time with my wife, two sons, and other family members (dogs, cats, and chickens).  

I lead an active lifestyle and activities that I enjoy include technical rock and ice climbing, canyoneering, mountain biking, 4x4 Jeeping, kayaking, and many other outdoor activities.

In the Berthoud Community, I assist the Berthoud Fire Protection District as a firefighter.  

Professional Commitment

Buying or selling real estate including residential property, agricultural property, or vacant land can be a monumental endeavor.  My personality, education, and experience are each assets which allow me to provide my clients with a high level of professional service.   My knowledge of the local real estate market allows me to assist sellers in pricing their real estate at a level that will promote the sale and maximize returns.  Similarly, my knowledge allows buyers to feel comfortable with the price they are paying for real estate.  Additionally, my education as a licensed professional geologist allows me to better facilitate transactions involving groundwater wells and septic systems, common among many foothills and mountain properties.  Whether you are a seller or buyer, I am committed to providing you with the professional and courteous service you deserve during these complex real estate transactions.  I look forward to assisting you with your current real estate needs as well as building a working relationship that grows in the years ahead.
