Client Testimonials
Rene Pierre St Laurent
David is the most technically and financially knowledgeable SR&ED tax credit advisor I have worked with. In addition to his detailed knowledge of the CRA's SR&ED rules and regulations, David has worked with our firm to reposition our activities in the context of SR&ED eligibility, thereby increasing our SR&ED refunds. David's past experience as an R&D Manager and Executive was also instrumental in helping our company to identify our key development activities. Perhaps most importantly, David & SKYMAX Consulting have helped our firm establish a solid reputation with the CRA, thereby facilitating subsequent SR&ED Tax Credit claims.
