Dr. Drew Pinsky, the host of radio call-in program Loveline, is leaving the show on April 28 after 30 years as its regular host.

The 57-year-old board-certified internist and addiction medicine specialist known as Dr. Drew wants to focus on other projects, including his current stints on HLN, the radio show Dr. Drew Midday Live with Mike Catherwood on 790-KABC Los Angeles and his Adam and Dr. Drew Podcast, which will expand to five days a week.

"I am not leaving radio,” he says in a statement. “The Loveline brand is still strong and perhaps we will bring it back some day. But for now, this version is ending and I will be focusing on all of my other projects. It has been a privilege to have served the listeners and share deeply in personal stories. I am deeply grateful for this opportunity."
