"I had an addition I wanted for our home. We were required to have a survey and an engineer drawing to apply for the permit. I had a list of 10-15 local engineering companies given to me by the permitting office. Very few would return my call. several the rest said they only do commercial or that this was too small of a job and would cost more. It was taking months and I was frustrated and decided to try Angie’s. I am so pleased. I had a response that very day I inquired for the job. It was clear what was needed from me. Great communication and answered questions to help me get them what they needed. The project from start to finish was drafted within 3 weeks. It could have been done sooner but I was traveling and not able to check emails. Once I told them to text me to alert me of an email they did that. I would highly recommend them."

"I placed a notice on Angi that I desperately needed an architect. I was given a list of 5 companies, however Campbell Architects (CA) contacted me first. As a matter of fact, I do not recall any of the other companies reaching out to me. When I tell you that Johnathan Campbell stepped in and did what I needed him to do which was to draw a PLAT of my property, he also went above and beyond what one would expect someone as busy as him to do. He came in and recognized that in addition to needing a PLAT, I was also having a terrible time getting the work on my property completed because a hostile neighbor continuously contacted the DOB with false statements causing me to incur numerous Stop Work Orders. When I asked Mr. Campbell what his experience was with this sort of thing, he told me and then offered his help. What I found was a very thoughtful, quiet, and professional architect who had seen it all. Not only did he understand the situation with the neighbor, he also understood my plight with the DOB and set about methodically, and very carefully stepping in to argue my case for me. He has the experience, he has the knowledge, he has the patience and he is an established and well known architect in this area, and highly respected at the DOB. It took me six months to get a response from the DOB, but once Mr. Campbell stepped in, it only took one day. My point here is that the magnitude of an individual's professionalism, knowledge and capabilities is reflected in the work product and engagement experience you the homeowner will receive. Here, Mr. Campbell made a WORLD of difference in my life as a homeowner trying to do her best against a system of mostly men who know the system, who can be cavalier and do not really care that we the homeowners have become frustrated with DOB. Mr. Campbell is an ANGEL. If you ever need an architect, he is your guy. He is a no nonsense kind of man who really, really cares about people and understands that most homeowners are "no match" for the DOB machine that controls the movement of homeowners here in the DMV. I am so grateful to Angi for creating a platform where I could find Mr. Campbell. I honestly do not know if I could have survived my nightmare ordeal without his knowledge, strength and capabilities. I now consider him to be a friend. I was shocked that he was willing to help me with the crazy man next door, but he took all of that on. He has made a difference in my mental health and ability to complete the work that I started, which the neighbor constantly stopped. I feel that I got more than an architect when I met Mr. Campbell. When people tell me they need an architect I always tell them JOHNATHAN CAMPBELL FROM CAMPBELL ARCHITECTS. This is the best company I have worked with in years. So grateful to have met him."
