Outstanding service! So easy to work with, helpful, and attentive in every way. I highly recommend using them for your trademark needs!

Few things are as challenging as following Federal regulatory protocols. For me, that's saying something, having worked in the securities industry for over thirty years! Mark Sentinel made filing my branding tagline simple, straightforward, and very informative. They truly take an "advocate" role for their clients.

I had a great experience at Mark Sentinel! My customer service representative was exceptional! She was professional and knowledgeable when explaining the process of how to copyright my work. She supported me until my work was ready for review. Mark Sentinel is well deserving of a 5-star rating.

WOW Mark Sentinel customer service is on point. I was struggling with my application process, and everyone I spoke to was helpful, knowledgeable, patient, and friendly... I would recommend Mark Sentinel to family and friends. Thank you!
