Ron is survived by his wife Arlene and four daughters; Traci, Ronda (Evan), Lori (Tom), and Shelli (Marcel), and four grandchildren, Reese, Douglas, and twins Danielle (Tanner) and Nicole. Born in Portland, Oregon on April 19, 1929, he was the second son of Dr. Frank and Ethel Trotman. He was preceded in death by his siblings Robert Trotman and Roger Trotman.

Ron met the love of his life, Arlene Lemler, in his hometown of Merrill, Oregon. They were married on June 27, 1954, the year before he graduated from dental school. After graduation, Ron and Arlene were stationed at Ladd Air Force Base, in Fairbanks, Alaska where Ron began his dental career. It was in Fairbanks where the first of their four daughters was born in 1958.

He practiced Dentistry for an unprecedented 61 years, retiring at the age of 87. Ron was devoted to his wife and daughters, all of whom he was incredibly proud of. He loved the outdoors and took many camping trips with their Airstream and enjoyed hiking and bike riding throughout the Pacific Northwest. The mountains held a special place in his heart. Ron taught his entire family to ski, and both he and Arlene skied well into their 80’s. Ron has climbed most of the Cascade peaks multiple times, including Mt. St. Helens and Mt Hood a total of eight times. Ron and Arlene enjoyed golfing and were members of Riverside Golf and Country Club for over thirty years. Ron was an avid runner and ran several marathons, ran the Hood to Coast Relay multiple times, as well as local Triathlon events well into his 70's. Ron enjoyed road bike riding and participated in several local biking events such as the Seattle to Portland Bike Ride (STP) and Cycle Oregon, and he rode his recumbent tri-bike as recently as two weeks ago. Ron and Arlene celebrated 65 years of marriage in 2019 and were looking forward to their 66th anniversary later this month. He was truly loved and will be greatly missed.

Dr Trotman was my dentist for 50+ years. Three generations of our families went to him and briefly to Rhonda as well. What a wonderful doctor and person.

When he sent me to a specialist, he praised Dr Trotman for his work.

We have missed him so much since his retirement. We are so glad he got to retire and enjoy life.

We send our condolences to his family. I’m sure you are all very proud of him and will miss him terribly.

Kathy Stapleton and the Carr family.

Dear Arlene and family,
I send my heartfelt condolences to you all. What a wonderful legacy Ron has left in his life work, his children and grandchildren, and all the people he touched throughout his life.
I started seeing Ron as my dentist at the age of 7 and he was my dentist until it seemed that driving 4 hours each way from my new home in Port Townsend was maybe enough at the age of 55.
I’ve never had another dentist as committed to the care of his patients. I have the utmost respect for his genius and innovation in dentistry around the role of bacteria and inflammation in dental care. He was a strong advocate early on that one’s oral health significantly impacted one’s overall well-being. Those of us fortunate to have had him as our dentist and friend have been the beneficiaries.
May you find comfort in the memories of a life well lived.
In sympathy and fond remembrance,

Ron was a lovely man. Always ready with a hug and a greeting.
Loved his family and was greatly loved by them. I will miss the family gatherings at Ronda and Evans and sitting next to Ron and talking together and enjoying his company.

He was our dentist as well. He was a wonderful husband, father, and grandfather and a legend in his profession. Our prayers and condolences go out to the family and friends of this great man. ♥️💔

I only know Mr. Trotman through one of his 4 beautiful daughters, Shelli. During the 20 years I’ve known her, conversations about her father were frequent. He created great memories and is with us forever.

Sending love.

I have so many wonderful memories of this very special man! His youngest daughter Shelli and I became friends in the first grade. We lived on the same street , and their house was my second home for many years to come. I was included in numerous trips and festivities while literally being treated as one of their own. I’m so grateful to have seen him in September 2018. We had a lovely conversation, and it is a comfort knowing my last words to him that day were, “I love you....”

This man will be truly missed by many as he inspired those around him! I had the privilege to work with Ronda for five great years. Her stories of her dad were the best especially, the skiing and camping ones. My heart goes out to the entire family during this time and may God provide the comfort needed during this difficult time.

I would like to send my sincerest condolences to the Trotman family. His daughter Shelli is a dear friend of mine who always spoke so highly of her father. Her love, respect and endearment for her father was enormous. May the family receive comfort and love during this difficult time.
