"I am an orthodontist and have worked with Jim Lancaster and OES on two offices in North Tarrant County. Building each office was a refreshing experience, with the project being simplified with a turn-key solution. Jim and his team at OES were on time and under budget. Jim Lancaster truly understands the market, and you are guaranteed that if he recommends a site for your professional office, that office will be very successful. Jim always puts your best interest first. If you are a professional, planning on building a new office, I would highly recommend Jim Lancaster and his OES team."
