A beloved HGTV host has died at just 55 after a private health battle that has left his friends, family, and co-workers in tears.

Loren Ruch passed away after a lengthy battle with cancer. He was serving as head of the network as well as co-host of the popular “HGTV House Party” program.

The Emmy Award-winning daytime personality had been fighting acute myeloid leukemia, a blood cancer that starts in the bone marrow, according to the Hollywood Reporter.

“Throughout his three-decade career, Loren was the rare leader who lifted everyone around him. Known for his unwavering dedication, endless kindness, and unshakeable integrity, Loren built not only hit shows but enduring relationships, serving as mentor, advocate and true friend to countless colleagues across the television landscape,” Warner Bros. Discovery chairperson Channing Dungey wrote in an email to staff (obtained by The Hollywood Reporter).

“His impact stretched far beyond the screen. Loren was the connective tissue of every room he entered — the glue that bound teams, departments, and friendships. He possessed the rare gift of making people feel seen, valued, and inspired to do their best work.”

“For Loren, work was never just about ratings or accolades, it was about people. He built teams that became families, forged friendships that lasted lifetimes, and leaves behind a legacy of creativity, compassion, and joy,” Dungey added.

“For those of us lucky enough to have known and loved Loren, the things we remember, and cherish go far beyond his professional accomplishments. We warmly recall the way he supported his team and his colleagues, celebrating their victories and lending a sympathetic ear when things were difficult. Loren’s light touched everyone lucky enough to know him. Though gone too soon, he leaves behind a lasting imprint on both the television industry and the lives of those who loved him.”

Longtime viewers of HGTV know Ruch for his reputation as much as his time on-screen. He helped build “HGTV Dream Home” and “HGTV Green Home” into dynastic programming for the once-struggling cable network, leveraging the camera shots and drama of reality TV to pack a punch in the construction, furnishing, and sale of suburban homes.

In recent years, Ruch had turned his attention toward a new generation of programming for the network, buttressing the production of “My Lottery Dream Home,” “Barbie Dreamhouse Challenge,” and “Celebrity IOU,” according to the Daily Mail.

Ruch was the recipient of five Daytime Emmys for outstanding work in reality TV.

Ruch is survived by his husband, David Salas; his mother, Dolly Norris; his father, Larry Ruch; and brother Geoffrey Ruch. In lieu of flowers, donations can be made to the Alisa Ann Ruch Burn Foundation or Be the Match.
