Their submittals and engineering are thorough and complete, field crews are knowledgeable and experienced, and their operations and support ensure that the customer's experience remains positive long after the initial installation. I highly recommend [TriMark] R.W. Smith as a supplier for environmental rooms."
- Michael St. Germain, Senior Project Manager - H2I Group, Inc.
"[TriMark] R.W. Smith & Co. has been my favorite supplier of cold rooms for at least 10 years. I have done many projects with them and thoroughly enjoy working with their field and office staff. They have never abandoned me or left me without a clear solution. They are prompt, always meet the required delivery and installation dates and are willing to work with other trades in the field as well as in the office to make sure all parties involved are aware of what is needed. Laura Bailey and Phil Summers have always taken care of me, over many projects and years of working together. R.W. Smith & Co. is always on the ball."
