"I feel privileged to have had the opportunity to learn from patrushkha and mark. I resolved many doubts about the profession of sound engineer. They gave us confidence. They are patient, funny and excellent human beings. I would like to continue learning from them in the future."

— Carlos Arredondo, sound engineer.

"I think this is really going to help students, super down to earth, logical and clear. I knew that it'd be a great book after your visits and sessions with our students. You're a wonderful speaker and your voice comes right through clearly and concisely in this book."

— Dr Andrew Knight-Hill, Senior Lecturer in Sound Design and Music Technology, Creative Professions and Digital Arts, University of Greenwich, London.

"As a creative media cluster, our mission is to connect, grow and promote Nuevo Leóns digital talent. One of our goals is to promote innovation and knowledge amongst all of the creative areas as: digital marketing, vr, ar, animation, interactive media, development, production, film, audio... and the best thing to achieve this is learning from the pros of the pros. Mark and Patrushkha not only show why they are known as "the sound pros of Hollywood", they are professional, they listen carefully to all of the students doubts, they show love and passion for their work, and they like to help them with their projects and the best of all, they keep a positive vibe in every lesson. Truly, one of the best instructors we had in our workshops. We are looking forward to work with them again!
