Mark was born in Western Nebraska and was raised on a cattle ranch. Living 60 miles from the nearest town meant the family had to learn to be very self-sufficient! That experience led to learning numerous skills and developing a good work ethic. He and Melissa moved to Estes Park in 1988 with 1 child and very little in the bank. In 1992 he decided to form his own construction company. He began as a framing contractor and then moved into general contracting. Throughout the years he has remained true to his values of providing a top-quality product to satisfied clients. Mark and Melissa have 4 children all raised in Estes Park and 5 perfect grandchildren, also being raised in Estes Park. In his spare time Mark has a number of diverse interests he which include: flying airplanes, golfing, fishing, camping, woodworking, learning the mandolin and gardening. If you stop by the office, he’d also enjoying shooting a game of pool!

Will Erickson - Operations Manager


Will Erickson

Will grew up in Estes Park and has a very eclectic background that has prepared him for this role. He not only has extensive experience within the construction industry, but he’s also been in restaurant management, worked in engineering/CAD and worked in a motorcycle shop. Construction has been the constant, however, as he built structures on the
family ranch as a boy and eventually working for his stepfather as a teenager. Will is known for his accommodating nature and fair-minded approach with clients. His personable skills, work ethic and honest communication immediately build confidence in those he works with. Will’s goal is to continue to build on the Westover reputation, that of building high quality, world-class mountain homes for satisfied clients.
Will is married to Jessica and they enjoy spending time together by walking their dog Ricky, dining out, paddleboarding and taking care of their house plants.

Brian Weber - Project Superintendant



Brian was raised primarily in Estes Park and is an Estes Park High School Graduate. He decided early on to go into the construction business. For many years he owned his own flooring business which served much of the front range. Being in that business, he found himself fixing mistakes made by others. He often wondered what it would be like to start a home from the beginning and be sure that the job is done correctly the first time! Though he has now had that experience, Brian finds that he enjoys doing remodel work primarily because of the challenge it presents. His goal as a manager is to deliver as close to a perfect product as possible. He enjoys seeing client’s happy faces once the job is completed. Brian is an avid fisherman. He’s happiest when he is camping and fishing with his two adult sons.

John P. Bostron

John was born and raised in northeastern Colorado on a family-owned, 4th generation, homestead farm.  Growing up he was drawn to architectural books and magazines, and his collection continues to grow to this day.  At the age of fourteen he found himself pushing a broom around a construction jobsite to pay for a broken window.  A happy accident of sorts, since it introduced him to the world he built his life around.  Architectural classes, school, and internships quickly followed.

Though his roots were on the farm, his heart wanted to be in the wilderness.  After the 2013 flood he seized the chance to go to Estes Park to work for a local architectural firm and made the move to the mountains.  He has a strong passion for historic preservation and a design style which blends with its surroundings.  He met Carey, the “girl next door” when he moved to Estes, and they fell head-over-heals for each other.  They realized they shared a love of old houses and soon bought a 1949 log cabin.  They spend their down time shopping for antiques for their home and exploring unique historic areas with old buildings to explore and stories to learn.
