 Trustindex verifies that the original source of the review is Google. John at Prismark made a stressful, time-sensitive process easy. We needed a document notarized and apostilled for use in Spain, and he handled everything quickly and professionally, including shipping the finished documents internationally via DHL. He answered every question, kept us updated at each step, and made sure the paperwork was done correctly the first time. Highly recommend Prismark to anyone who needs notary or apostille services for international documents. Thank you, John!
