"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!"

"We worked with Patrick Zampetti at Studio Z when we opened our gym. This was our first experience with a facility design and build-out so we had lots of fears and concerns. Thankfully Patrick put us at ease with his knowledge, experience and professionalism. He has done this for decades so he was able to point out so many things we wouldn't have even thought of. Looking back after 5 years of operating our business and there isn't a single thing we think we missed or should have done differently with our layout and design. I would highly recommend Studio Z for anyone looking for an architect to help with their home or business."

"the owner was a very nice man - i learned a lot from him. He will be used on any new home plans i need, with high praise!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Matthew gave me professional advice while I was reviewing possible house purchases. A wise investment."
