Michael F. Costello, age 61, died Saturday, February 13th, following cardiac arrest due to lingering symptoms from Covid-19.

Born on February 8, 1960 in Pompton Plains, New Jersey, to Jane and Jerry Costello, Michael was a graduate of De Paul Catholic High School in Wayne, New Jersey. He continued his studies at Franklin and Marshall College and began a 20-year history working as a loan officer in Lancaster, Pennsylvania. When Mike moved to Silver Spring, Maryland, he worked as a loan officer for Weichert Realty. Although he was a life-long Mets and Giants fan, Mike’s number one sport was golf. An avid golfer, Mike’s favorite player was Jim Furyk, “The Grinder,” who went to high school in Lancaster County. Mike admired Furyk for his unique swing and no-nonsense approach to the game. Michael’s love of golf led him to work at Kenwood Country Club in Bethesda, Maryland. For more than ten years, Mike enjoyed the Club’s rolling hills and the banter with club members while working at the golf shop, as a manager in the dining room, and as a starter on the course. Most recently, Mike worked at Mon Ami Gabi restaurant in Bethesda where he was considered “family” and where friends and colleagues from Kenwood would often visit Mike to share stories and lots of laughter.

Known for his wicked sense of humor, his relentless teasing, and his rapid-fire responses, what Mike would not reveal were his selfless acts of kindness for friends and acquaintances in need. On more than a few occasions after hearing that friends were having difficulties in their marriages, Michael didn’t hesitate to reach out—even if it meant a long bus or train ride, to deliver his message: “You have a beautiful wife and family. Don’t make the mistakes I made that I regret to this day.” His advice was always taken to heart. If there was a need, Mike would be there to listen, to offer help in whatever way he could, and to help others learn from his life experiences. Throughout the pandemic, Mike gave great comfort to his 89-year-old mom and dad, as he called them often during the week to check on their health, give updates on his, and as a stock market enthusiast, remind his father to “let Mom order whatever she wants when the pandemic is over because her stock is doing much better than yours.” For many years, Mike was a sponsor in the AA Program.

Mike understood the beauty and the pain of the world and perhaps that is why he most identified with Furyk, “The Grinder.” Mike knew what it meant to face life’s adversities and like his favorite golfer, he tried to find ways to grind out a strong finish on tough courses under the toughest conditions. Mike wasn’t always victorious, but just as Furyk was elevated to the status of “the grinder of all grinders,” so too was Mike. In May, Mike contracted Covid-19 and continued to fight against the lingering symptoms of the virus right to the end.

Mike loved to share stories with family and friends about his two sons, Grant, a sophomore at the University of Maryland, and Joey, a senior at Gonzaga High School in Washington, D.C. He took great pride and derived great joy in how his sons approached school, sports, and work, and most of all in how they lived their lives. Mike was loved by his many nieces and nephews and for years to come they will remember his “legendary, unusual, and epic” dance moves that put him in the center of the dance floor at family weddings. Mike loved music, especially the songs of Bob Dylan and Neil Young. He dabbled with guitar and sang their songs with passion though not always in tune. In his final weeks while suffering with Covid-19 symptoms, Mike felt relief and joy listening to Dylan songs performed by his friend and brother-in-law’s band.

Mike is survived by his two sons, Grant and Joey, and his best friend and life partner, Francesca Mazzaglia Costello. He is also survived by his parents Jane and Jerry Costello of Pompton Plains, New Jersey, his sisters Nancy Rishty and her husband Joey of Mechanicsburg, PA; and Eileen Marx and her husband, Joe of Lawrenceville, NJ; his brothers Brian and his wife Rose of Edmond, OK; John and his wife Veronica of College Park, Maryland; and Bob and his wife Evelyn of Morristown, NJ. Mike is survived by many loving nieces and nephews: Nicole, Ray, Bobby, Teresa, Kevin, Chris, Katy, Kyle, Carly, Clare, Patty, Charlie, Sebastian, Matteus, Shannon, Robbie, Logan, Kellen, and Cameron. Mike is also survived by Francesca’s siblings: Domenic Mazzaglia of Rockville, Maryland, and Josephine Veliz of Silver Spring, Maryland, and his nieces Angelica and Grace, and his nephew, Zachary.

May you rest in God, Mike. May your fairway drives travel straight and far, and may you stay forever young.

Mike and I began working together as starters at Kenwood on the very same day, August 16th, 2008. I always looked forward to seeing and talking with Mike over the ten years we worked together in the golf shop and in the starters booth. I would never walked away without a smile after being around him. He was so easy to talk to and made everyone around him feel so comfortable and upbeat. If you ever needed a helping hand, Mike was there.

I did made Mike very jealous about 3 years ago when, through pure chance, I got the opportunity to play a round of golf with Mike "Fluff" Cowen, Jim Furyk's current caddie and former caddie of Tiger Woods at Northwest Park Golf Course in Silver Spring. I immediately texted Mike when I realized who I was being paired up with and as you can imagine he was beside himself! Unfortunately he was working in the golf shop at Kenwood that day. I wish there was some way he could have joined me. It would have been one of the highlights of his life!

I was so saddened and shocked to hear of the passing of Mike when I returned to work at Kenwood this year. He was one of the nicest human beings that I have ever met. We were all very lucky to know him. My thoughts and prayers go out to the Costello family.

Whether on the golf course or in the dining room Mike ‘s upbeat attitude and kind attention added to our pleasure when enjoying Kenwood’s links or a meal. John and I, our kids, grandkids and guests always thought of Mike as one of the club’s assets reflecting the friendliness of a family club. He was missed when he left. Our condolences to his beloved family. We’ll drink a toast to a really great soul.

I met Mike around 2007. He was going through a rough time, but had the determination to overcome it. He apparently did. He was a very honorable man. He used his life experiences to help others and would freely share with them about his path. I am very saddened to hear about his passing. My condolences to his family and friends. May peace be with Mike and all who knew him. Godspeed Mike.

I am writing this on behalf of my entire "Stewart" family. We were all so sorry to hear of Michael's passing and wanted to extend our sincere sympathies and to let you know that you are all in our thoughts and prayers at this difficult time. The Stewart and Costello parents have been friends for a long time so this hits close to home. We hope the memories and love that you share with each other helps.

Whether you were in the grill or at the starters booth no one made you more welcome than Mike. With a wry smile and a wicked sense of humor we touched on all the topical events of the day. My prayers and blessings go out to all Mike’s family. You will be truly missed my friend. Chris and Jean Fowler

To all that knew Mike, but especially to his parents, Jane and Jerry, his sons Grant and Joey, and to Francesca...I did not know any of you, but I can tell you we sure knew Mike at Kenwood . I can never remember a time when Mike did not have a smile on his face and he had such a way of always putting one on mine as well. Always in such a wonderful, positive mood, and always selflessly asking how I was doing. I can’t imagine what a difficult, tragic loss this is for each of you, but try to take comfort in what an amazing person he was and the wonderful joy he brought to us here at Kenwood. I’m so happy to call Mike “friend”. Our sincere condolences to each of you.

I am so sorry to hear of the passing of my friend Mike Costello, when I hired him as a starter I had no idea what a valued employee he would become. Always a gentleman with a easy to like personality, he quickly made Kenwood home and became friends with so many Members.
He had a knack for bringing out a smile from most every contact. RIP

I was very saddened to hear the news of Mike's passing. "Mikey"the way I used to call him, was a very kind and affable person always in a good mood and willing to accommodate at the golf starting booth. He displayed exactly same attitude at the restaurant which made dining by far more pleasurable. My condolences go to the entire Costello family.
