Philip De Fazio

Real Estate Agent, Husband & Proud Dad of 3

Real estate has been in Philip’s blood since childhood. He grew up watching his aunt build her own brokerage from the ground up — inspiring him to follow in her footsteps and help families find the place they can truly call home.

He works with all types of properties but has a real soft spot for detached homes and pre-construction. There’s nothing he enjoys more than handing someone the keys to a home that’s brand new and built just for them.

Philip knows South and Northwest Calgary like the back of his hand and has been loving the growth and community feel of the Southwest. Outside the city, you’ll often find him helping clients in Okotoks and High River — two places he describes as “small-town charm with big heart.”

Clients describe Philip as honest, straightforward, and easy to talk to — someone who turns transactions into relationships that last for years.

When he’s not with clients, you’ll find him spending time with his family, playing with his kids, or at church on Sundays. His dream home? A traditional-style acreage with plenty of room for the kids to stay close… even in their 30s (maybe 😅).

His motto says it all: “Whatever you do, work at it with all your heart, as working for the Lord.”

MARIANA RAMZI

Real Estate Agent, Local Expert, and Proud Mom 💗

Mariana has proudly called Calgary home for over 15 years and knows firsthand how important it is to find more than just a house—it’s about finding the place where your life happens. As a mom to two daughters, she understands that a home is where the little everyday moments become lifelong memories.

Specializing in Calgary’s South communities, Mariana brings real knowledge of local schools, family-friendly neighbourhoods, and the lifestyle that comes with them. Whether you’re buying your first home, upsizing, or investing, she’s here to guide you with honesty, care, and confidence.

Mariana discovered her passion for real estate through her own homebuying journey—and never looked back. With a background in business and years of hands-on experience working in her family’s company, she’s all about building genuine relationships and making sure her clients feel supported every step of the way.

When she’s not out showing homes or negotiating deals, you can find her chasing her kids around Chuck E. Cheese, sneaking in a strength class at F45, or unwinding with a glass of wine on a sunny patio. She loves exploring new local gems and connecting with the people who make Calgary such a vibrant place to live.

KATUS WHITWAM

Real Estate Agent & Resident Cool Cat 🐱

With a decade of experience in the fast-paced world of hospitality, Katus thrives in environments where personality, problem-solving, and human connection come first—so naturally, real estate became her next great love. Whether it’s navigating high-stress deals or simply finding the perfect vibe in a home, Katus brings calm confidence and genuine care to every client she meets.

Specializing in condominiums (yes, she’s officially certified!) but passionate about all kinds of properties, Katus loves how every client brings something unique to the table. Her favorite part? Helping people find their “forever” place—and watching how personal preferences shape each search.

She grew up in Airdrie and now calls NW Calgary home, making her an expert in both communities. And while clients love her honest approach and down-to-earth nature, she jokes that friends would probably just call her “the coolest person you’ve ever met” (and they’re not wrong).

When she’s not showing homes or hosting open houses, you might find her knitting with her cats, sipping wine with loved ones, or exploring downtown Calgary’s live music scene. Oh—and for five summers, she managed a floating restaurant on the Shuswap, accessible only by boat or water plane. Yes, she literally lived at work—and loved every second of it.

Katus dreams of one day settling into an acreage in Rocky View: close enough to the city for business, but peaceful enough to enjoy evenings on a quiet patio.

If you’re starting your real estate journey and want an agent who’s authentic, approachable, and just a little bit adventurous, Katus is ready to help you find your way home.
