About Mario

I've spent more than 28 years helping buyers and sellers navigate real estate with confidence. I bring a diverse background to real estate--offering clients construction insight, psychological awareness, business acumen, and unwavering advocacy. I have strong negotiation & clear communication skills, and pride being hands-on from start to finish -- especially when transactions get complicated. Known for listening carefully and working tirelessly, I am dedicated to guiding clients through every step of the process with honesty, expertise and care. I'm a consistent multi-million producer and have been recognized nationally among the top 5% of agents for sales performance.
I work with a wide range of clients from luxury and relocation buyers to sellers of historic homes and new construction. As a side note, for more than 23 years, I have served as a tour guide in the historic Allegheny West community, sharing my passion for architecture and local history during the Christmas Victorian House Tour and Summer Wine & Garden Tours. My goal is simple: make the process smoother, smarter and less stressful while delivering results my clients feel good about and consistently call me back.

Home Types: House, Townhouse, Condo, MultiFamily

Years of Experience: 29

Education: BA in Psychology, John Carroll University
