Our Story

The real estate industry is built upon relationships; and what better relationship to build a company’s foundation on then that of family. A brother-sister duo, Alex and Mariella Massa saw the housing market’s need to improve the appraisal process. They began their careers in the appraisal industry while in college and saw great opportunity to do things different and better. The siblings partnered to build their first appraisal company, Initech Appraisals, in 2005 which eventually led to the growth of Appraisal MC. They now operate one of the largest independently owned nationwide appraisal management companies in the industry. Their unique synergy and respect for each other and the appraisal industry as certified appraisers are just a few of the numerous things that make Mariella and Alex Massa successful in today’s appraisal world. Alex and Mariella complement each other in that they have strengths on different sides of the spectrum. Mariella is an industry thought leader and guides the company as a big picture visionary while Alex increases operational efficiencies and serves as a subject matter expert in appraisal compliance. They combine their strengths to develop and implement processes that serve Appraisal MC’s clients and purpose well.
