Josh Ulberg developed a passion for the building trades at a young age. Growing up in the building industry, Josh loved to help his father on jobsites and that love grew into a very clear vision that the construction industry was the career path for him. After graduating from Ferris State University with a Building Construction Technology degree, he went into the residential construction field full time. From 2000 to 2007, Josh worked with his father and brother building new homes and fabricating custom cabinetry. In 2007, Josh began his sole venture as Josh Ulberg Builders, LLC. At this time Josh’s passion became a healthy obsession for developing a superior custom home tied with creating personal client relationship that would last a lifetime. With this mindset, Josh was able to accumulate many successful projects into his portfolio and customer loyalty relationships that brought him repeat business. Knowing that God is always in control, he had another plan for Josh. So, with much prayer, and now thankfulness, Josh and Lucas merged their talents to form Viking Construction Group in 2017. Josh resides in Jenison, MI with his wife, Kimberly, and three children.
