"Being a small business within the defence industry and having limited resources available, we decided to engage De Stefano & Co to support and assist us with our DISP application. Emilio and his team, especially Brian McAvoy were fantastic to work with, they did all the hard work which allowed me to focus on other aspects of our business. No stress, straight forward and efficient. Thanks to De Stefano & Co we were able to gain our DISP accreditation in short order."

"I can't speak highly enough
about Emilio and his team of professionals, who have become a vital part of our team. They have assisted us with many projects, all have been of a high standard with very successful outcomes. I recommend you do yourself a favour and contact Emilio, you won't regret it."

Our business, QMS, has worked with De Stefano & Co very closely over the past year in obtaining SADI grant funding. I can honestly say that Emilio, Tracy, and the entire team are without a doubt experts in their field. Not only does this team provide successful grant applications assistance for grant funding, they are never too busy to help in any way that they can. At De Stefano & Co, I always feel like I am their top priority. I would highly recommend this company to any other company seeking all types of grant funding. QMS will certainly be a customer for life.
