MT Trim Co was established in 2020, but our roots in carpentry started more than 25 years ago. Founder Matthew Whiteis grew up learning the trade from his father and older brother, who both inspired him to create his own company. Having a creative and analytical mindset, Matthew loves the challenge of custom projects. 

Currently, MT Trim Co subcontracts through Custom Trim. If we are unable to take on your project directly, we will put you in contact with their team to provide you a quote and to determine if your project can be done by us or another skilled carpentry team.
