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.

Randie Wareham

Randie Wareham


Growing up in Arizona I have learned to love and appreciate its natural beauty, from the Sonoran Desert to the high desert mountainous community of Flagstaff.

I was fortunate to be raised by a family of investors, realtors, engineers and contractors. This environment gave me the tools to be self-motivated, goal oriented, dedicated and honest in all that I pursue. These traits extend into my relationships with my clients, my friends. As a long time local resident I am a good resource to help you navigate the many unique neighborhoods Flagstaff has to offer. I am proud to be part of our community, super grateful for the ease of access to explore our natural lands and to also be a piece of the happiness that drives this city to be as awesome as it is! It was only a matter of time before I met my husband and we started our construction company together, began our own real estate adventures, became a mother and obtained my real estate license.

We have made Flagstaff our home for over 20 years and counting! Biking, hiking, digging in the dirt, designing, adventuring, along with hosting dinner parties with family and friends are just a peek into what drives me.

Flagstaff is an awesome place to live a healthy, adventurous, successful lifestyle, and to call home!
Let's get working together to continue your dreams!
Sunshine, Smiles, Randie?
