Melissa Prusky
With over 35 years of business experience, I proudly joined the investment industry more than 20 years ago.
As an entrepreneur at heart, I've founded, grown, and successfully sold two businesses. This firsthand experience has provided me with deep insights into the importance of capital preservation, strategic growth, and financial security—perspectives that uniquely inform my approach to supporting my clients. I’m dedicated to creating personalized retirement roadmaps, offering guidance every step of the way, and adapting dynamically to each client’s evolving needs, whether their goals are short-term or long-term.
Through the exclusive "Mandeville Difference," I customize portfolios for clients, blending private and public investments guided by the Framework of Wealth Creation.
As a divorced mother of two grown daughters, I understand the unique financial considerations that women face during various life stages. I have a special passion for empowering women through financial education, clear communication, and careful planning, helping them confidently manage and grow their wealth.
A graduate of George Brown College, I started my business journey in 1983. Today, I'm a fully licensed Investment and Insurance Advisor with certifications in CSC, CPH, WME, and LLQP.
Philanthropy holds a special place in my heart, especially initiatives focused on rapid diagnostics for breast and ovarian cancers. As a founder of Oakdale's Golf Fore The Cure, we've raised over $2 million for Princess Margaret Hospital Foundation and Sunnybrook Hospital Foundation. Giving back is an essential and fulfilling part of my life.
Outside of work, I cherish time with my family, including my two daughters, son-in-law, and grandson. I also love traveling and golfing whenever I can.

After earning my bachelor's degree from the University of Guelph, I began my financial career with a prominent U.S. investment firm before joining forces with Melissa Prusky in 2018. Together with our dedicated assistant Andrea, we've built a team focused on exceptional client service and results.
In my downtime, I love staying active by playing squash and tennis, as well as traveling to explore new places.
I live in Toronto with my wife and our two children.

I joined Melissa and Martin in 2018 and have loved being part of the team ever since. Over the years, I’ve had the privilege of supporting the growth of our practice and take great pride in the work we do together for our clients.
I manage a broad range of administrative tasks—from opening new accounts to processing deposits and withdrawals, coordinating transfers, tracking statements, providing quotes, conducting research, and assisting with online access. Since entering the industry in 2015, I’ve taken on many different roles, and I genuinely believe there’s no issue I can’t help solve. I hold both the CSC and CPH certifications, which help me provide strong, knowledgeable support to our clients and team.
Melissa and Martin have also supported my husband and me in our own financial planning, and we follow the same trusted approach that we offer to each of our clients.
I live in the Greater Toronto Area with my husband and our two children. Outside the office, I love to travel and spend as much quality time with my family as possible.

I'm thrilled to be part of the Prusky-Garcia Team, which I joined in 2025! With a background in both financial services and real estate, including fulfilling roles at Mortgage Group and BMO Bank of Montreal, I’ve developed a passion for building meaningful client relationships and delivering personalized care.
I'm naturally organized and approachable, always ensuring our daily operations run smoothly—whether managing account details, coordinating client communications, or providing steady support behind the scenes. My goal is to foster warm and trusting connections with both our clients and the wonderful people I work with every day.
When I'm not at work, you'll find me enjoying family life in the Greater Toronto Area with my husband and our two children.
