On the morning of November 9, 2021, with his daughter, Marilyn, by his side, Dr. Justo L. Mari, 94, was called home to join his wife, Diane, and son, John, after a long battle with dementia. Justo was born on May 12, 1927, in Alaminos, Pangasinan, Philippines, the ninth of ten children, to Dr. Justo C. and Rosa deLeon Mari. Justo enjoyed his childhood in Alaminos, although he often talked about the disruption of his family during the Japanese occupation of the Philippines, during WWII. The schools closed, and his family had to move to the country. His father was a physician and pharmacist, and always told him that he should be a priest or a medical doctor. Justo chose medicine, and after graduating from the University of Santo Tomas Medical School in Manila, Philippines, he moved to Fargo, ND in 1954, to complete his residency and internship at St. Luke’s and St. John’s Hospitals. During this time, he met Diane Erickson, a nurse at St. John’s Hospital. At first sight, Diane knew he was the one and wasn’t getting away. They were married on June 1, 1957. While completing his residency, his supervising physician noticed Justo’s talent for suturing, and encouraged him to pursue a career in surgery. He and Diane moved to Minneapolis to complete his surgical residency at Minneapolis General. Jeff and Marilyn were born during this time. Knowing his love for the outdoors, hunting and the lakes, a colleague invited him to Bottineau, ND, where he took a position as a general surgeon at St. Andrew’s Hospital in 1961. John and Jackie were born during his time in Bottineau, where the family lived until 1975. A friend, who was a Fargo Clinic partner, offered him a position as an Emergency Room Physician at St. Luke’s Hospital. The family moved to Fargo, ND in December 1975. Justo worked in the ER for 10 years, followed by 5 years in immediate care, and retired in 1992. After his retirement, Diane and Justo were blessed to be able to spend the next 20 years between Arizona and Little McDonald Lake in Minnesota. In his free time, Justo enjoyed spending time at the lake, fishing, hunting, and smoking his daily cigars. During his years in Bottineau, he was a member of the Country Club. He never picked up a golf club, but spent every Wednesday evening at the club playing poker. He was a man of few words, but loved to tease and joke with those around him, even in his final years at Kinder Care in West Fargo, ND. Justo was preceded in death by his wife, Diane (December 16, 2020), son, John (November 6, 2021), parents, eight siblings, granddaughter, April Beth Mari (March 1, 1989), and many other dear relatives and friends. Carrying on his legacy, all in Fargo, are his son, Jeff (Kaley) and daughter-in-law, Lynne, Mari; daughters, Marilyn (Dr. E. James) Werre, and Jackie (Dr. Daniel L.) Mengedoth. Grandchildren, Sydney (Patrick) Stoa and children, Remy and Jaxon; Chanel (Brent) Malone and son, Marshall; Dr. Jordan (Dr. James) Muir and daughter, Jocelynne; Katelyn (Zach) Frappier, and daughters, Mari and Koa; Audra Mari; Jade Mari (fiancé Davis Geske); Jarett Mari; Max, Austin, Samuel and Simon Mengedoth. Also left to mourn his loss is his sister, Virginia, Philippines, and many other nieces and nephews.

(Justo also saved me from trips to the doctor with my kids which was greatly appreciated.) It is sad losing them . My condolences to the family.

  9. Jeff, Marilyn and Jackie,
    What wonderful times our families did have! My dad has been waiting for Justo to join him! In my heart, I am going to believe they are rejoicing and living free of pain! I am not sure heaven was ready for the Ohnstad, Mari, and VanSickle group! Mom and Dad loved your parents and all of you! My mom still talks about the Mari boys always stopping to see her at the lake! If only we could be young again and camp out by our cabins, stomp on ketchup packages as we walked to the drive in and let’s not forget Jeff only wanted meat on his hamburgers! Just think how many times we would go to Canada and not go through Customs or even have a passport! Oh the stories we could tell! I hope that put a few smiles on all of your faces during this time of tragedy! Virtual Hugs to all of you and I wish I could there. Please know I will be thinking and praying for all of you! Much love! Kathy Berard (Ohnstad)

  10. Im sorry to hear about Justo. My mom was at kinder care care. And he was such a fun person to be around. Him and my mom used to tease each other. In some ways it helped her deal with being there at first. Again Im so sorry for your loss. Chris Larson family

  11. Thoughts and prayers to all of Mari families during this most incredible difficult time.
    Scott, Kristin, Zach, Erica and Jake Peters

  12. In our little town of Bottineau, it was such a gift to have a fine local surgeon. When I was a second grader, Dr. Mari did a expert job stitching up a deep cut across the arch of my right foot.

    I also recall going to Dr. Mari’s office with classmates Lori and Marilyn to get our ears pierced.

    May your family find peace and consolation in loving memories of a life well lived.


  13. Marilyn, Jim and Family,
    We are saddened by the passing of your Dad and Brother. While your Dad may have longed for relief, your Brother passes far to young. Our prayers are with you and your family and also with your Dad and Brother as they make this heavenly journey together.

  14. Such a wonderful loving family. It was such a pleasure getting to meet John when he would visit Justo he was always smiling and so happy, and it was such a pleasure caring for justo (papa) for the past year he was truly a man of so few words but the ones he did say always made you laugh and meant so much. Sending prayers to you all in this time of great sorrow
