Testimonials

I contacted Ms. Massarello concerning the many questions I had about the social, political and religious concerns of 15th century France and, specifically, those of Geoffroy Therage, the man who is purported to have been Joan of Arc's executioner. Ms. Massarello's research not only answered all of my questions in a remarkably quick and efficient manner, but she was also able to expand on the material in question. Her presentation of materials was both succinct and thoughtful, and I was thrilled to find that she had unearthed details regarding the subject in question of which I had absolutely no previous knowledge. Her research was thorough and yet presented in a concise manner that allowed for quick reference. Ms. Massarello's research assistance to my writing project was invaluable.
