Jim Greenfield – Founder and President

Columbia Builders opened their doors in 1975.  With master’s degrees in both civil engineering and business, and over 50 years in the building industry, I have watched CBI grow and evolve to what we are now—a small team of professionals, dedicated to homeowner relationships, building personalized and custom homes for our clients.  I grew up in the Adirondack Mountains of New York and currently reside in Columbia.  I am married with six children, and two grandchildren.  When I’m not enjoying family pursuits—including snow and water sports—my greatest joy is giving back to the community through a variety of local charitable organizations.

Tracy Davis – Customer Service Coordinator

Raised in Indiana, I relocated to Maryland, joining Columbia Builders in 1999.  I coordinate the details of your settlement, and upon completion of your new home, I am your contact for questions and customer service.  On my off-time, the outdoors call to me—hiking, camping and gardening are my favorite things to do.  My love of hiking and adventure has taken me to some wonderful places including Canada, Ireland, New Zealand, and most of the United States.

Ron Tash – Project Manager

A native of Maine, I have been a part of Columbia Builders since 1990.  My responsibilities include administrative and construction management.  I enjoy meeting new purchasers for their pre-construction meeting, pre-drywall walk-through, and home completion orientation.  Residing in Howard County, I am an avid cyclist and runner, enthusiastically participating in century rides and several marathons over the years.

John Liva – Service Technician

I was born and raised in Northern California, and after my service in the military, began what is now a 40 year career in the building industry.  In 1989, I joined Columbia Builders, assisting new homeowners both before and after the settlement of their home.  Outside of work, my favorite activities include spending time with my grandchildren, hunting, fishing, gardening, and especially cooking.  I always enjoy exchanging recipes too!

Karen Kehoe – Sales Manager

I have been affiliated with Columbia Builders since 1999 and take great pleasure sharing more than 30 years of home design and construction experience with buyers.  I enjoy guiding families through the planning and building of a home that is uniquely theirs!  With two grown daughters, my husband and I enjoy living on our horse farm in my native Baltimore County.  Travel, sailing and visiting with friends are among my favorite activities.

Carole Vogel – Marketing Coordinator

With over 35 years in new and existing home sales and marketing, I enjoy helping the public learn about and connect with CBI, through our website, social media, e­newsletters, blogs and more. I am a lifelong resident of Central Maryland and a great resource to anyone new to the area as well! I love spending time with my two grown children, my canine side-kick Quincy, and planning my next coastal vacation!
