Mack & Letty B Take Mornings At 93.9 MIA Miami

My 93.9 MIA WMIA Miami Beach Joey Brooks ValentineiHeartMedia Hot AC “93.9 MIA” WMIA-FM Miami Beach has announced it will launch “Mack in the Morning with Letty B” on Monday, April 1.

Mack moves to WMIA from afternoons at CHR “Y100” WHYI, while Letty B joins the station from 102.7 KIIS-FM Los Angeles where she currently hosts weekends and overnights and previously middays. Nick Pena will serve as producer of the show.

93.9 MIA, Variety from the 80s, 90s and Today, announced today the debut of “Mack in the Morning with Letty B,” effective April 1. “Mack in the Morning with Letty B” will broadcast weekday mornings from 6 a.m. to 10 a.m.

“Mack in the Morning with Letty B” will star popular Miami on-air personality Mack, Los Angeles native co-host Letty B and producer Nick Pena. The new morning show will broadcast the latest entertainment and lifestyle headlines catering to the local Miami scene as well as entertain listeners with interactive games and news.

“I am excited to announce Mack, Letty B and Nick as 939 MIA’s morning team,” said Joey Brooks, 93.9 MIA Program Director. “Not only is this group entertaining, but they are committed to the South Florida community. Individually, each of them brings a unique perspective to the show and I am confident that they will quickly earn listener loyalty.”

“I enjoyed my time as afternoon drive at Y100 and I’m excited to kick off a new chapter at 93.9 MIA,” said Mack. “I’m grateful for the opportunity to take the next step in my career to morning drive here in Miami. It’s a good thing we have Cuban coffee!”

“I am beyond thrilled to join 93.9 MIA and the amazing iHeartMedia Miami team,” said Letty B. “I can’t even begin to describe how excited I am to join Mack on this incredible journey to wake-up with Miami every morning.”

Note: An earlier version of this story inadvertently mistook this Letty B with Letty Baltazar who co-hosted with Big Boy on KPWR Los Angeles. We apologize for the confusion.
