Licensed & Insured.Established in 2005. Baron Tech (formerly known as BaronSweeps) is a small company with a big heart! We have been providing services for over 10 years in the area and still going strong! This business was first begun by my father and previous owner Oscar Olazo, who spent a great deal of his own personal time working double as he used to previously work for a company and serve his own customers at the same time, usually working late hours everyday in order to help support our family. He, then, finally decided to provide his customers 100% of his time to ensure that his customers were satisfied and opened what was Baron Sweeps. With his recent passing, I , Oscar Jr, who went side by side with my father since day 1, have taken lead and continue to provide the service my father dreamed of for his company.
