Testimonials

“Rocks & Cornerstones was a huge asset to our North Broad Street project. Especially in regard to any dealings we had with the City of Philadelphia. Her knowledge of the process and people skills helped navigate that typically painful interaction with little to no friction. Additionally, despite the challenges that surfaced during construction, her professionalism and positive energy through the entire process was always welcome as she assisted us in opening our beautiful space to the public.”

Ethos||GSFM – Jonathan Jacobs

“We have worked with R&C for several years and have been extremely happy with their services. They have helped manage construction projects, coordinate and plan with sub-contractors and architects and streamlined our permitting process. We are happy to have them on our team.”

Hill Investment LLC – Joe Hill

“Had a full kitchen renovation and I am absolutely pleased with the results. New cabinets, granite, moved location of appliances and Bose designed the entire thing. She did all shopping providing a wide arrange of options for us to choose from. Very responsive and did not ask for final payment until after her last walkthrough to ensure all final details were completed. Will work with her again, already planning our next project.”
