Obituary of Marshall Joseph Duguay, PhD.

Passed away on Sunday, August 28, 2022, after a lengthy decline in health, at home with his family by his side. He was very brave, never once complained and showed us all how to die with courage and dignity. He leaves behind his beloved wife Linda Kremer-Duguay. Loving father of his twin sons Christopher and David (Kimberly), Duke, Lynne, Brian (Emily), and Grandpa of 6 grandchildren. He will be missed by the mother of his children and friend Bettyann Duguay. Predeceased by his brothers Douglas and John.

Marshall was a Professor Emeritus at the State University of New York College in Buffalo. Early in his career he worked at Roswell Park Cancer Institute where his expertise in speech rehabilitation with patients who had lost their larynx led him to become the world’s leading expert in esophageal speech. He lectured worldwide in the USA, Canada and Europe. At that time, he taught more people to speak again than anyone in the world. Special thanks to Dr. Rohani and the dedicated and compassionate nurses and therapists on Unit C at the Greater Niagara General Hospital and his palliative care nurses Liliya and Geneva.

Arrangements are entrusted with Essentials Cremation and Burial Services. In accordance with Marshall's wishes, cremation has taken place and a private family gathering will be held at a later date. In his memory, donations to Roswell Park Cancer Institute would be appreciated. Online condolences may be shared on Marshall’s tribute page found at

My sincere sympathy and condolences to the Duguay Family on your loss.
Dr. Duguay was my Professor and Mentor at SUNY Buffalo State.
With Marshall’s inspiration and encouragement, I have had the pleasure of working with Laryngectomee Patients for nearly 5 decades. He was an internationally recognized expert in voice rehabilitation for the Laryngectomee and we were so fortunately to have him here with us in WNY.. His legacy lives on through all of his many former students from Buffalo State that have gone on to successful careers as Speech-Language Pathologists

Marshall was one-of-a-kind. He was smart, funny, compassionate, and generous. A man of many talents. I had the pleasure of having him as professor. He always encouraged me. His classes were fast paced and never boring. His lessons stuck with me till this day. My deepest condolences to his family.

He will be missed.

Marshall had a unique sense of humor, and a compassionate heart.
We treasure the numerous ,funny, greeting cards he mailed to our mother for the three years she lived in a nursing home
He was a truly special ,loving, and humble person.

My deepest sympathies to the family. Dr Duguay was my favorite professor at Buffalo State and I learned so much from him. His practical ideas mixed with humor are still something I remember to this day more than 30 years later.

Nearly 50 years ago, Mr. Duguay came to my grammar school a couple of days per week to help me with a lisp and other minor speech impediments. I vividly remember his good nature and the way he involved me in helping to shape my own improvement. He left a great impression on me and was instrumental in supporting my development. I’ve never forgotten him, and I’m sure his life of good work will keep him in the thoughts and prayers of countless others for many years to come. My sincere condolences to his family at this difficult time.

His professional accomplishments were outstanding and I learned so much from him. I also had the good fortune of knowing him as a dear friend. He was fun, talented and kind. I will cherish all of the wonderful memories with Marshall and feel truly blessed to have known him. I know he is already bringing smiles and chuckles to the angels in heaven!
