Diane Gunkel Obituary

Diane Gunkel (née) Lo Castro, just shy of her 70th birthday, passed away peacefully on Saturday, Dec. 6, 2025 at her home with her husband by her side.  Born in New Brunswick, NJ, she attended Villanova University post-graduation from East Brunswick High School.  She worked for the prosecutor's office in New Brunswick for several years. After raising her 2 sons (her primary focus), she worked in a dental office for many years, retiring 3 yrs ago.  She attended Abiding Presence Lutheran Church in Ewing and spent many years volunteering. Diane had a big personality, great sense of humor and was sharp as a whip.  Besides enjoying spending time with her family, she enjoyed annual girl’s trips with her high school friends.   She also enjoyed her monthly dinners and craft nights with her group of friends from Ewing. Diane loved to cook and host large family holiday dinners. She also loved to dance, especially to Motown tunes.  She will be deeply missed.


She is survived by her parents Richard and June Lo Castro, her beloved husband of 46 years Frank K. Gunkel, her sons: Randall Scott Gunkel, wife Peg of Mt. Laurel, Adam K. Gunkel of Xenia, OH, and her stepdaughter Jennifer Marie Gunkel of Columbia, MD. Her sisters: Andrea Greenspan, husband Brian of Plainfield, NJ., Karen Noa, husband Gary of Galloway, NJ, Lynn Lo Castro of Abilene, TX, and sister-in-law Gretchen Lewis, husband Peter, of Skillman, NJ.  Three grandchildren: Callum and Cole Gunkel, Cassandra Marks, and a great grandchild Mateo. She is also survived by many loving nieces/nephews and great nieces/nephews.


A gathering to celebrate Diane will be held on Saturday January 17, 2026 from 10:30 am to 12:30 pm at the Peppler Funeral Home 122 Crosswicks St. Bordentown, NJ. 08505

I worked with Di at the Prosecutor’s Office. Vacationed with her and her super nice friends one summer on Long Beach Island, remember her green convertible mustang, when she met her future husband in Plainsboro, attending her wedding, and sitting around the dining table at her home in Ewing the 1980s while our very young kids played together. A very sweet and a very wise woman. So glad we got a chance to catch up a year ago.

I am grateful for our friendship that has lasted through all life's trials, tribulations and triumphs. I love you Diane and I will miss you deeply.

Our dancing queen and the sister I never had. From cruising in the mustang to crazy times in Plainsboro. From helping pick out my wedding dress ( with approval from 3 yr old Randy) to decades later helping pick out the dress for my son’s wedding. My bff. You were always there for me. You are forever etched in my life. I will miss you beyond what words can express. I love you Di.

Our High School reunion

I first met Diane in middle school in science class. She was smart, pretty and teacher's pet. Everyone loved her. She was open, kind and generous. We reconnected at our high school reunions and later on girl's trips. Her positive spirit and courage always shone through, and it was always a pleasure spending time with her. I will never forget her. Sending prayers to her family and loved ones.

Remembering the fun and friendship. with heartfelt sympathy

Diane was a wonderful and caring neighbor and friend. We used to dance to a band called Fat Chance at Charlie’s Uncle in East Brunswick in the late 1970’s. She was always a positive person. She loved to laugh. I and my family (Grattan) will miss her. God Bless her and her family. Love Nancy Grattan Parisi
