Jeremy went on to join Massie and Co, as a third generation real estate developer. Over the past 15 years, Jeremy has been involved in planning development, sales, leasing, contract bidding and forecast development. Jeremy’s experience has involved, but has not been limited to the building of tilt up warehouse buildings.

It is the attention to detail that drives his desire to be involved in the custom home construction industry. He has most recently built six custom homes in the golf course community of Catta Vedera, as well as a number of spec homes in the area.

 

Among Jeremy’s greatest success, he would consider his involvement in both local and global philanthropy.

From a global perspective, Jeremy has served oversees in Kenya, Africa with his church, helping to develop a compassion based church in the slums of Africa.

 

His role as a father and husband is what brings Jeremy the most joy. He has been married to his wife Amy for 17 years and has two beautiful young daughters. Family is Jeremy’s priority, followed closely with being involved with Bayside Church. In Jeremy’s free time, you most likely will find him on his road bike climbing the backcountry roads of Loomis, CA.

Coleman Warren

Assistant Superintendent

Coleman’s introduction to the construction industry was as a 14 year old young man helping his father build houses entirely by themselves, from the footings to the ridge cap. Although he gained some valuable skills and knowledge in the building industry, and loved being able to see the fruits of his labors at each days end, he did not stay in it for long.

 

Coleman always felt that at some point in his career he would return to the building trade, which he recently did. In 2014 he and his father spent 2 years restoring a home listed on the state’s historic register, having been owned in 1865 by the Governor of Nevada. At the conclusion of the project he was co-recipient of the Carson City Historical Builder of the Year award, a highlight of his career.

 

Coleman realized that if he could combine his affinity for project management with the construction skills he learned as a young man, he could create the perfect job for himself, which he did here at Catalyst Builders.

 

Coleman loves the outdoors, the mountains, and living in a climate that experiences 4 seasons. He is married and is the proud father of 5 children and 2 grandchildren.
