Mark T. Belsanti

Mark T. Belsanti, CCIM Mark T. Belsanti, CCIM

Founder / Owner

Mark has been an active commercial real estate agent for over 20 years. He has enjoyed much success through those years; transacting commercial real estate in Flagstaff, Sedona, the Verde Valley, and Scottsdale, Arizona.  In 1999, he attained the Certified Commercial Investment Member (CCIM) certification.  This certification is one which separates a commercial real estate agent from the general real estate agent.  A CCIM is a recognized expert in the commercial and investment real estate industry and a CCIM is part of a global commercial real estate network with members across North America and more than 30 countries. This professional network has enabled CCIM members to close thousands of transactions annually, representing more than $200 billion in value. As a result, the experts who possess the CCIM designation are an invaluable resource for commercial real estate owners, investors, and users.

As well, Mark served as a Planning and Zoning Commissioner for the City of Sedona for three years prior to relocating to Flagstaff, Arizona in 2003. At that time, he started da Vinci Realty with his wife, Leslie.
