'I must say that my experience with Zach the project manager and his team was terrific. They guided me along in the editing and process and were not only helpful but patient. Zach was a personal pleasure to deal with. I also learned along the way and was able to even improve upon my own writing and punctuation. He was always responsive to my questions and problems.'

'Kudos to the amazing team and for sure the people behind it. I've been struggling to publish for years and on a fine October morning I call Sigma Publisher and get connected to Daniel. Since then they have made my dream possible and thank you Zach for being available throughout the entire process, and whatever of an issue I'd, he responded me with patience and dedication. I felt heard and I'm glad my book "An Art of Love" is out there and seeking your love for the same!'

'I finally connected with Daniel Green after being introduced to a few staff members. This review reflects my experience with Sigma Publisher as a direct result of Mr. Green's exceptionally professional and personable manner. My goals were reviewed and created to avoid confusion. Opportunities to further develop the creativity of my project(s) were made available - and resulted in explosive success! APS offers various services; however, finding the right agent made all the difference to me. I was not rushed or exploited. Daniel Green was very attentive to my personal preferences; such was the determining factor to remaining a client.
Thank you,'

'I struggled for a year trying to get my book published. I was able to do everything from the art and writing but couldn't find a way to get my book out there. Daniel and his team made it possible and did it so fast! Most places charge you an arm and leg, but they offer amazing deals you can't beat. I will continue to go to them for my future books They made it so easy!'

'Daniel Green has been very available and helpful in publishing my children's book. We had a few miss communications and some editing problems but in the end the book is just as I had hoped. Daniel was always courteous, patient and ready to help with all the issues this first time publisher had. Thanks'

'I created a children's book and considered it to publish as self-publishing by KDP. But it's a debut book, and I worried it doesn't look professional because of poor formatting, so contact Sigma Publisher. Most of all, Mr. Frank Cooper is an excellent manager. He helped to publish them one by one as if he is a personal coach. Thank you so much!'
