Lindsay (President) & David (CEO) Lamb

Lindsay and Dave founded OSR in 2016 after careers spend serving clients' facility-related needs throughout Pittsburgh.  Instead of being "across the table" from their customers, they align with their customers to navigate the many complex projects and services needed daily at facilities.  OSR's success is fueled by what they call R-squared...repeat and referral business.  They look forward to serving your needs as well. 

Dave and Lindsay reside in the North Hills of Pittsburgh with their two small children, Vera and David.
