Grant was one of my-closest friends, we’ve known each other for a very long time. We shared many memories, thoughts and laughs together. I will truly miss this inspiring individual. His passing has left a deep wound in my heart, but I do have many memories to fall back on.
You are a true hero. RIP my brother.

Allison Yates says:

When I first met Grant I knew he was a colorful character. Once I got to know him I knew I was blessed to call him a friend. He always had a story to share. And he always had a jalapeño for a snack and offered to share. He lived hard and loved hard. He will be missed by so many, but we all have our stories to allow us to never forget a legend. A true hero.

Grant was a great guy. We worked as partners on the FCTF US Secret Service. He never met a bad guy he wasn’t willing to chase. Rest easy my friend. We got it from here.

Lyndon Johnson says:

I’m really gonna miss my friend Grant we were wht we called across the alley neighbors. Grant and Terry always looked out for me and my family and watched over my home when I was out of town. One day they got together and decided to stain my fence I told them they didn’t have too , but they just told me they were bored and needed something to do. Also when we had the bad ice storm last year Grant saw me and my son out shoveling snow and ice in the driveway he brought over his blow torch so I could melt the snow/ice to get out for work… he was just that kinda guy. Rest easy my friend miss you already.. LBJ

Joe Pondrom says:

I met Grant in 1974 when I transferred to HQ Btry 2/14 in Dallas as the new Bn Comm Chief. This was quite a crew of Marines but Grant was the ringleader even as a Cpl. We became friends and had many good times together both as Marines and deputy sheriffs, which there isn’t enough space here to cover even a few. Grant called me the afternoon he passed wanting some information about our old Marine unit as he was working on a reunion plan. You are missed my friend. Fair winds and following seas Marine! Semper Fi!

Laura Boatright says:

Didn’t know Grant real well in school but I sure remember how cute he was!
Always real sweet to me when the opportunity came around!!

Ginger Lee Edwards says:

Did we know the same guy?

Franklin Hinton says:

This is such a loss to our group and he will be missed dearly. He was a guy with an incredible resume and life. Although it was not immediate in talking with him, Grant was an extremely valuable asset in his many facets of service to our country and some very powerful individuals in his earlier career.

Grant was like his employee#, 67976… he was the same from both directions, he harassed everyone with the same level of disrespect… Just joking, not really 😊… I thought a lot of Grant and considered him a true friend! He always kept me on my toes when he was deployed and always had a joke or a laugh to share to make the day better.

Rest in peace, Grant!!! Happy Birthday and Father’s day! I’ll never be able to look at Coffee, Hog wings, or Jalapenos again without thinking of ya… I’ll miss you, buddy.

Janice Pugh says:

Precious one. Some people enter our lives and quickly go.Others enter our hearts, and we are never the same
All the love we shared, all the love you gave will forever be in our hearts (brokenhearted as the are now). We have been truly blessed with you, God’s gift to our family. The shared juneteenth birthday with Cleve fun unlimited with jokes, laughs and meat loaf birthday cakes. We know you rest in the arms of Jesus and we’ll meet on the other side. Always, Nanny & Cleve.


I’ve known Grant since we were crib buddies in the early 1950’s. Our parents were very close and played a lot of bridge. He was a year behind me at TJ. I still fondly remember a trip to Port Aransas that we took following my graduation from TJ in 1969 with his Mom Jan. When Grant later joined the Marines my Dad wrote a letter to Grant every other day while he was at boot camp to keep his spirits up. Unfortunately our paths diverged after we each got married in the mid 70’s. We only spoke sporadically after that. Grant reached out to me a week before he died saying he wanted to get together for a cool one. We met at his favorite bar in Richardson and had a terrific three hour visit, got caught up on things, and planned another meeting with my wife, and my brother and his wife. Sadly, Grant passed away the next day. I will always regret letting all those years get away from us. Grant was truly one of a kind with his infectious belly laugh, razor sharp wit, and kindness to others. I will miss him a lot!! SEMPER FI GYRENE!!!!


Unlike any other experience in this life, losing a friend or family member absorbs our memories to realize how much we will miss your presence. Just as the evening of a day leaves a remnant of a forgotten day, you won’t be forgotten. You rode life like a bicycle and kept your balance toward family and friends, through your smiles, laughter, and kindness along the way, I can only say… I will miss you Jack Grant and thank you for being a friend at heart.
