Heidi J. Diamond

12/08/1958 - 12/03/2025

Beloved Daughter, Sister, Aunt, Mentor, and Trailblazing Media Executive

December 8, 1958 – December 3, 2025

Heidi J. Diamond, a radiant force of brilliance, warmth, and unstoppable love, passed away peacefully on December 3, 2025, in New York City, NY, just five days before she would have celebrated her 67th birthday on Monday.

From her roots in Silver Spring, Maryland, Heidi built an iconic career that reshaped entertainment and media: launching Nickelodeon in the UK, leading networks at Food Network, GSN, AMC Networks, and Martha Stewart Living Omnimedia, driving digital health innovation at HealthiNation/GoodRx, and later championing women founders as co-founder of AngelHive, CEO of Diamond Enterprises, and Venture Partner at 125 Ventures. An adored adjunct professor at LIM College, she mentored countless rising stars with the same fierce belief in them that she had in herself.

Nothing lit her up like family and friends. She was the devoted daughter of Larry (Deceased) and Vicky, the heartbeat of her siblings Jeffrey, Brett, Georgia, and Laurie, and the world's most cherished aunt to Lexy, Charlie, Erin, Austin, and Noah plus godmother of four. She showed up for every trip, game, graduation, heartbreak, and triumph with ice cream, advice, and arms wide open. To her countless chosen family and friends, she was simply irreplaceable—the one who always answered, always remembered, and always loved without limit.

Heidi is survived by her mother Vicky Diamond; brothers Jeffrey and Brett; sisters Georgia and Laurie; nieces Lexy, Charlie, and Erin; nephews Austin and Noah; and an enormous circle of mentees, colleagues, friends and loved ones who will carry her light forever.

Thank you, Heidi, for teaching us that living fast doesn't mean living shallow—it means loving deep, showing up fully, and never, ever leaving anything important unsaid or undone.

A celebration in NYC of Heidi's extraordinary life will be announced soon. In lieu of flowers, the family kindly requests donations to the American Heart Association (http://heart.org) or organizations supporting women entrepreneurs, or simply performing one bold act of kindness in Heidi's name.

We love you forever and we will miss you endlessly. Thank you for every fierce, beautiful, love-filled day. Happy early 67th in heaven, our dear Heidi.
