Martha (Martie) Marie (Hayes) Dumas, age 82 of Natick, Yarmouth Port and South Yarmouth, MA Passed away on July 20, at the Terraces in Orleans, MA.
Martie was an extraordinary woman. As a wife, mother, mentor and inspiration, she touched everyone she met. Throughout her life she took advantage of the opportunities that became available to women.
Born in Chelsea MA, she grew up in Auburndale, as the oldest of four children of William and Martha Hayes: Regina Kamyck, William Hayes, and Marian O’Sullivan.
She graduated from St. Mary’s High School in Waltham, where she met her future husband, Joseph (Joe) S. Dumas at a senior play they performed in. Two years later she graduated with an associate’s degree in medical Secretarial Science. She then ran an office at Boston University Hospital, now Boston Medical Center.
She married Joe before his senior year at Boston College. A year later their son Kenneth was born and the family moved to Buffalo, NY where Joe attended graduate school. Their son Tim was born there, and Joe received his PhD in Cognitive Psychology. Martie taught herself to become a seamstress and began to take university courses. When the family moved to Rochester Michigan, where Joe became a member of the Psychology Department at Oakland University, she started a dress-making business while continuing to take courses.
When the family moved to Natick, Martie attended Framingham State College and received a Bachelor of Science degree in Economics and Computer Science. She worked as a demographer at Boston Edison and as a software developer for a time-sharing company. She then joined the finance division at Zayre Corp., later TJX. She advanced to the position of financial manager of TJX’s Systems (Communications and Computer) Division supervising her own group.
During those years, she guided Ken and Tim through their school years and into college while encouraging Joe in his career.
Around the age of 50 she gave up her finance position to attend Simmons University, where she received her master’s degree in social work and, two years later, her Clinical Social Work license.
After receiving her Social Work license, she started her own psychotherapy practice in Natick where she helped clients with their relationships and work-life issues.
In 2004 Martie and Joe moved to Yarmouth Port in Cape Cod, where they continued their careers while enjoying the Cape lifestyle. In 2007 Martie was diagnosed with a brain tumor, a meningioma, which was treated with neurosurgery and radiation, ending her psychotherapy practice. In 2014 she and Joe published a book about the way the brain tumor changed their relationship, Relationship Rewired: A couple survives the effects of a brain tumor
For the next decade Martie took up painting and began writing stories, fiction and nonfiction, an anthology of which will be published soon.
Martie is survived by Joe, Ken, Danielle Tim, Joanna and Nina.

My sincere condolences to you and your family on your loss.

I had the pleasure of having Martie as a yoga student and then she became my friend. It’s hard to connect with people as you get older but Martie and I instantly connected over our love for yoga and reiki and all things spiritual. She has a beautiful kind spirit and I felt so lucky to have spent time with her. She was also a mentor and really helped me through a rough time when my mom was sick. I’ll miss you Martie.

as a proud grandson of william and emma hayes i offer my condolences to your family.

Joe , Donna & I are so - so sorry to hear of Martie’d passing . I’m in tears for my favorite “Cousin” and his Beautiful wife, Martie and her family . Love, always .. Cousin Jim & Donna YarmouthPort

Please accept my deepest personal sympathy and genuine solace

Aunt Martie was one of a kind. Compassion and Kindness overload. She used to host our Thanksgiving Holidays at her home and was always the gracious hostess. She continued to educate and elevate herself throughout her life! She will always be an example of what hard work, perseverance and compassion for others brings to your life! She will be greatly missed by myself and my sister Marsha. Blessings to her dedicated husband Uncle Joe, and Cousins Kenneth and Tim and their families.

An amazing story of Martha's life ! Our hearts go out to the family and all those who knew Martha. This wonderful woman will be missed.

I will never forget spending time with you at The Natick Service Council in the 1990s. I'll always remember your great sense of humor and infectious smile. You were a very special woman. My condolences to your family and friends. Jonna

To Billy Hayes, we extend our sincere condolences to you on the sad loss of your sister Mattie. Although we never met her she obviously led a full life and reared a wonderful family. May her soul rest in eternal peace. Liam & Kitty.

Joe and Family. We are so sad to learn that Martie has died. She has been a fighter for a long time as you all have been. We will catch up by private letter. Our heartfelt condolences.

Martie was a lifelong friend. How lucky was I ! We went to the same kindergarten. and the same church. She loved people, and they loved her back. She is a heroine to me. She has had many major health obstacles,, and she met each with courage and a determination to find a path forward.. She became a wonderful writer, painter, and an avid reader when her mobility was impaired. Quality of life mattered to her, and she actively tried to enhance the lives of those around her. She lived a remarkable life with many achievements. She will always be remembered and missed.

I already miss you Martie. You were a wonderful person. Thank you for all you did for me. Love, Marian (little sister)
