Dennis Mongeon, 85, of

Mandan, passed away

March 18, 2020, sur-

rounded by his family.

Dennis was born on

January 3rd, 1935, in

Rolette, ND. He graduat-

ed from Rolette High

School in 1952. Follow-

ing high school he pur-

sued a career in education

and received his teaching

diploma from Minot State

University. He also at-

tended St. John’s Univer-

sity in Collegeville, Min-

nesota. After graduating

from college, he married

Carol Jean (Myrum)

Mongeon in Anaheim,

CA, on June 8th, 1963.

Dennis and Carol then

moved to Mandan where

he began his teaching

career with the Mandan

Public School District,

where he dedicated 28

years to teaching students

at Mandan High School

and Mandan Junior High.

Dennis was an avid

sports fan and coached

numerous sports through-

out his career, including

golf, where he was the

head boys and girls coach

for numerous years. He

also was an assistant for

football, basketball, wres-

tling and cross country.

Dennis had a positive im-

pact on many of his stu-

dents and athletes

throughout his career. He

also officiated many

basketball and football

games around the state.

Dennis’ impact carried far

beyond retirement and

when his former students

and athletes saw him in

the community they regu-

larly stopped to share his

impact on their lives as a

teacher or a coach.

During his teaching

career Dennis also worked

summers as a crop hail

adjuster and after retire-

ment continued this work

for many years and en-

joyed meeting people

from all over the state

whom he always remem-

bered. When mentioning

a last name, Dennis could

identify where they were

from down to the mile

marker and landmark to

where their farm was.

Dennis loved his fami-

ly. He was a great hus-

band, father, brother,

grandpa and great-grand-

pa. He did whatever he

could to make sure he

could attend as many

sporting events as possi-

ble of all his kids and

grandkids. His brownies

were a major hit for all the

grandkids. He would

often just randomly drop

off plates of them for all

the grandkids to come

home and discover on the

doorstep. He was also an

avid golfer and became a

pillar around the Mandan

Golf courses. He even

stepped in for a brief

period to manage the

Municipal Golf Course.

He was able to golf all the

way through the summer

of his 84th birthday. In

addition to his love for

golf, Dennis enjoyed the

outdoors fishing and

hunting. He was also a

die-hard Minnesota every-

thing fan; Twins, Vikings,

Gophers, North Stars and

Wild. Whether he was at

home, on the golf course,

out fishing, or anywhere

away from home, he had

to have the Twins on. He

was a Minnesota faithful

and they lost a great fan.

Dennis also spent a

great amount of time with

many of his lifelong

friends and family at the

local gathering spots to

have coffee, play cards, go

fishing, or just stopping

by for a visit.

Dennis was a kind and

generous man, always

putting others’ needs be-

fore his. Dennis’ faith

was important to him and

he passed that on to his
