About us

Built from the mountain top

Ioannis “Yanni” Karakostas is a second-generation Greek-American, born and raised in Boston, MA. His passion for craftsmanship began at the age of 7 when he first set foot on a roof, working alongside his father, Dimitrios, who instilled in him the values of hard work, precision, and dedication to the trades.

Yanni’s family heritage is rooted in generations of skilled masons from the mountainous regions of Greece, where his ancestors built and restored entire villages using nothing but stone.

Όρος“Oros” means mountain top in Greek, Yanni’s commitment to elevating each project to its highest potential.

With Yanni at the helm, Oros Builders brings tradition, expertise, and relentless dedication to every project, ensuring it reaches the pinnacle of quality and craftsmanship.
