Agent Profile
Eleven years ago, I started a second career in Real Estate sales, following a successful career in International Operations with Xerox Corporation.
Real Estate has been both rewarding and fun, managing listings and sales in Darien, Rowayton, and the surrounding communities including New Canaan, Norwalk, and Stamford.
I can attribute success on either the listing side or selling side to four factors that I feel are critical to serving residential real estate customers:
- Strong knowledge of the market, and knowing first-hand the excellent services available to residents and families in the area;
- Providing a high level of expertise, professionalism, and personal service in supporting the client or customer during the sales process;
- Representing the customer or client's interest exclusively, throughout the selling or buying cycle; and
- Building and maintaining a solid relationship with the client or customer with constant communication.
Client communication is Key. "I am on call 24/7. I am picking up the phone on the first ring and providing valuable information - and it's the same response time with text and email. In this business, it's imperative to be responsive and I give that commitment and expertise to my clients and customers."
A graduate of Fairfield University and Columbia Business School, my wife and I have been Darien residents for more than 30 years raising three wonderful boys. Should you or someone you know be in need of real estate services, I can be reached by phone or text at 203 921-5059 or by email at rcallahan@halstead.com.
