Simply put Doc is a real one! His cut to his professionalism is one that left a lasting impression. I have received fades around the world and I’ll put Doc up against the best. If you are lucky enough to get him booked you won’t be disappointed.

Doc has an amazing shop that is always extremely clean and inviting. His skills with the blades are the best in the east bay, and you won't leave unsatisfied.

I have spent 5 years looking for the right barber. I have traveled everywhere from: Pittsburg, Antioch, Concord, Vallejo, Fairfield and nothing comes close like Undefined Fades does. David A.K.A. “Doc” is a surgeon with the clippers, shears, blade and everything in between. He takes pride in his work and as a dedicated veteran to his craft he prioritizes safety and sanitation. His knowledge of hair is impeccable and what is even more impressive is his knowledge of the head. He understand head shape and recommends cuts and blends that complement your head.The only feedback I have is that he can run late. Meaning if your expecting 45 minutes to an hour haircut give yourself at least 30 minutes extra. This is due to him not rushing your haircut and their being a high demand for his specialty. He doesn’t rush you in and out of the chair like others barber do. He enjoys what he does and it shows in his cuts.P.S. Doc brings the barbershop culture to his shop so every conversation has soul to it.

Great place to get a cut or fresh look!! Doc did a great job cutting my hair. He asks many questions to make sure you get the cut and style you want.

Diego is an amazing barber and very personable. Prior to going here, I had issues finding good barbers, but he knows his stuff well. Never left feeling like my hair didn't look good.

I was extremely satisfied with my haircut from Doc. I’m new in Brentwood so this is my first time trying a new barber. Doc did not disappoint. I’ll be going to him on a regular basis.

Doc has been my barber for a couple years now. Probably the best barber I’ve ever been too. His haircuts are always the same if not better each time. He values your time, which I think is the most important thing to me.. a lot of barbers I’ve been to run behind and they don’t give you a heads up so you’re waiting there for hours on end not knowing when you’ll be next... Doc Always gives you a heads up in advance if he’s running a few minutes behind schedule. He’s always really kind and respectful. He listen to what you want, always making sure you are satisfied. 10/10 barber. Hard worker, Great quality haircuts. Clean shop. I definitely recommend.
