Picture
​"Engineers John Thomas, Erika Bolger and [their] team greatly support our architectural work with solid mechanical, electrical and plumbing Permit, Bid and Construction Documents.  When working with clients, John is quick to provide timely and accurate solutions that resolve important code and logistical problems that are created with the many conditions that we have on our new and existing building projects.  I have been working with John for about 17 years."
