Stephen was awesome! We were in a pinch to get escrow documents notarized and we contacted Stephen through Thumbtack. He was helpful, responsive, punctual, and professional. He helped us understand the documents as well! We would highly recommend!

Stephen went above and beyond by accommodating our need to reschedule our appointment last minute due to an emergency and even came to the hospital to get our documents notarized on a Sunday

Stephen provided notary service on two consecutive occasions to my visually impaired, elderly mother. Stephen was very patient and went out of his way to explain the documents to my mother and properly notarize them and then even went the extra mile to mail out the documents for us.
His services are very fairly priced and his punctuality and professionalism are on matched.

Stephen was great to work with. We needed a notary on short notice and he was very flexible and able to work with us even after having to change the date a couple of times. He was very responsive, ensuring all my questions were being answered in a timely manner. I highly recommend Stephen's notary services. Additionally, given the type of person he demonstrated to be with me, I would also extend the recommendation to all services he provides.
