“Jeff had to redesign many aspects of our office to be in line with our corporate standard. He did so with ease. He really kept our project on track and ran everything. He coordinated weekly construction meetings, gave us useful ideas on how to use the space and followed up with our vendors personally to make sure Frank Crystal received everything they needed. Jeff remained positive throughout this whole project and his attitude was infectious. He was a pleasure to work with. This was my first time working on an office build out and Jeff took me through every step and was so helpful.


I truly enjoyed working with him and wish I had his services with me when I worked on 2 other projects that were frustrating because I did not receive the same level of service that I did from Jeff.


Anyone who gets to have Jeff work with them on projects is lucky. He is a true professional and is very easy to work with. He may have a whole slew of clients, but you would never know by the level of personalized service that Jeff gives. I recommend Jeff Tathwell's services to anyone who is looking to redesign their space.”
