I have been publishing books for eleven years in my country. I have friends involved in the same kind of work all over the world. But I have never met a graphic designer as talented, as creative, as industrious, or with more integrity than Mario Kushner. Graphic designers are a dime a dozen in most countries — especially in large cities. But finding one who is every bit as committed to customer satisfaction as he is to producing exceptional design-work and layout is difficult to say the least. Such men are exceedingly rare jewels. Mario is a five carat diamond! He has been my first choice among graphic designers for more than five years. You will not find anyone more committed to making things look EXACTLY the way you want them to look. (Even when you're not initially sure HOW you want things to look!) I simply cannot recommend him highly enough.

I enthusiastically recommend Mario Kushner's work as a designer. He has not only proved himself to be a gifted artist with the ability to capture in picture what is described by word, but he is also a diligent worker who can handle the pressures of deadlines and budgets.

I heartily recommend Mario’s work. He is easy to work with, speedy in his response to your questions and emails, and is a creative genius. He will not stop working until you are 100% satisfied with his design. We at Didasko have decided that we will only use him for our graphics work from here on out.
