"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"Aaron was timely in response and was quick to schedule an inspection. Willing to travel and very reasonable in price even with the travel expense added in. I would recommend Aaron for verifying the structural soundness of a foundation and will definitely keep his name in my list of preferred business professionals to work with."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"He is a brilliant architect. I live in an old home which is always tricky. He designed our master bedroom in a 90 year old house in a way that didn't need any major structural changes. It looked as though the house was originally made for that design! The design he came up with also included everything down to the last detail. He does quality work and the guys he works with clean up after themselves. In the beginning of each project he extrapolates what it is that you are looking for. He doesn't try to push his latest design on you. His focus is solely on what each customer wants and he is very open minded to the taste of each client. He is incredibly efficient and I have never seen anybody work the way he does. Trent is very good at avoiding mistakes and his communications skills are excellent. He is very knowledgeable in his field, and because of that he completes projects very quickly and delivers high quality results. It is fun working with Trent because he makes it easy!"
