A’tera 519 Appoints Executive Chef Alexander Diaz, Introducing a New Era of Contemporary Coastal American Cuisine

A’Tera 519, the AAA Four Diamond flagship restaurant of Basalyga Hospitality Group, proudly announces the appointment of Executive Chef Alexander “Alex” Diaz, a classically trained culinary professional whose career spans more than three decades in fine dining, luxury hospitality, and culinary leadership.

A graduate of the prestigious French Culinary Institute in New York City, Chef Diaz received classical French training under internationally acclaimed chefs including Jacques Pépin, André Soltner, Alain Sailhac, and the late Gray Kunz. Their influence helped shape the technical precision, discipline, and ingredient-driven philosophy that define his cuisine today.

Following graduation, Chef Diaz continued his professional development under the mentorship of Chef Luc Dendiviel, former Executive Chef of the celebrated Bayard’s in New York City. He later expanded his culinary repertoire through advanced training in Barcelona, Spain, with Lizarran Tapas, where he immersed himself in traditional Spanish and Mediterranean cuisine.

Throughout his career, Chef Diaz has worked in some of the Northeast’s most respected kitchens, including the legendary Jean-Georges during its acclaimed four-star era, Brasserie, Palma Restaurant, and Il Mulino New York. These experiences refined his ability to combine classical European technique with contemporary American cuisine while building high-performing culinary teams dedicated to exceptional hospitality.

Before beginning his culinary career, Chef Diaz proudly served in the United States Army, where he received formal food service training through the Quartermaster School and the Academy of Health Sciences at Fort Sam Houston, Texas. The discipline, organization, and leadership developed during his military service continue to shape his management philosophy and standards of excellence.

Chef Diaz has also shared his culinary expertise through collaborations with Food Network and Telemundo, further demonstrating his passion for education and the craft of cooking.

At A’Tera 519, Chef Diaz is leading a renewed culinary vision centered on Contemporary Coastal American cuisine elevated by refined French and Mediterranean influences. His seasonal menus emphasize pristine seafood, premium meats, locally sourced ingredients whenever possible, and modern techniques grounded in classical foundations.

“Great restaurants are built by great people,” said Chef Diaz. “My goal is to create a culture where discipline, creativity, and teamwork inspire excellence every day. Every dish that leaves our kitchen should reflect craftsmanship, integrity, and an unwavering commitment to our guests.”

Under Chef Diaz’s leadership, A’Tera 519 enters an exciting new chapter while continuing its tradition as one of Pennsylvania’s premier fine dining destinations and reinforcing the standards that have earned its AAA Four Diamond distinction.
