Senior Project Manager (Marketing)

As a Senior Project Manager, Rayvee has been integral to the success of our ongoing developments. Rayvee's communication is top-notch, and his support was invaluable to our success. On many occasions performing work outside his area of expertise and juggling multiple roles simultaneously. He has helped find and train others to support the work while requiring little management or oversight. I enjoy working with Rayvee and look forward to our continued work together.
