"The guys from Obsidian came for one issue that was a non-issue, and pointed out how water around my house was slowly damaging to the structure of the home. They did not try to sell me anything, and solely wanted me to understand how I could improve the water flow around my home. I am a gardener and they suggested a rain garden with the rerouting of my water, which was wonderful! They pointed out the damage, which was noticeable. The first structural engineering firm I had was all about sales, never pointed out the water issue, and said the cracks in the interior walls needed to be fixed immediately, and I could call JES. Obsidian was all about making sure my home stands in a healthy way for many years to come! They said the cracks in my walls were repaired prior to me moving in and had just reopened -- no big deal but normal settling (1963 home). They are honest and ethical and I would call them again in a heartbeat!"

"Patrick and his team took time to understand all aspects of the project and goals before design. Professional to work with and would recommend with the highest confidence."

"Martin was great - he was sharp and knew his stuff. He listened carefully and provided sound direction where needed. He was very responsive and provided clean, detailed drawings that I was able to get through permitting with few revisions. All at a reasonable price. Would highly reccomend."

"Evolution Drafting did a great job modifying my existing plans and updating for Arizona codes and took care of the structural engineering as well."
