Ariane Biagini Cowper
Residential & Commercial Real Estate Broker
Associate Broker
Raised in a bilingual household on the Westmount flats, Ariane was immersed in the world of real estate from an early age. As a third-generation broker—and descendant of John Hand, a distinguished builder whose work helped shape Westmount and Notre-Dame-de-Grâce—Ariane brings a heritage of craftsmanship, architecture, and deep local insight to her practice.
Ariane earned her French Baccalaureate in Economics and Social Sciences at Collège International Marie-de-France before pursuing Humanities and Communications at McGill University, specializing in Art History—an influence that refined her eye for design, quality, and aesthetics. She later completed a post-graduate degree in Public Relations at McGill and continued her studies in New York City, earning a degree in Fashion Marketing from Parsons School of Design. Her professional journey through sales, marketing, public relations, and operations management has shaped a well-rounded, strategic, and client-oriented approach.
Ariane is often described as a “tranquil force”, known for her calm demeanor, determination, resilience, and industrious nature. She values integrity, trust, and discretion, offering each client a highly professional, attentive, and thoughtful real estate experience.
Since beginning her real estate career in 2021, Ariane has worked closely with her colleague Karen in a dynamic and rewarding partnership. Under Karen’s mentorship, she was exposed early to a wide range of transactions and an exceptionally thorough approach to client service. Together along with Allyson, they are committed to exceeding expectations and guiding buyers and sellers through every step of the process with clarity, care, and expertise.
Allyson Kassie
Residential Real Estate Broker
Associate Broker
Known for her sincerity, honesty, and unwavering dedication, Allyson is a trusted professional who takes pride in delivering the highest level of service at every stage of the process. For her, success is never measured by the bottom line—only by the confidence and satisfaction of her clients.
Allyson’s professional journey began in 2004 when she opened Bloom Maternity, the first high-end maternity fashion boutique in Montreal. What started as a personal passion quickly grew into a celebrated retail destination recognized for its style, service, and forward-thinking approach. Allyson’s ability to anticipate client needs, curate exceptional experiences, and build meaningful relationships formed the foundation of her career.
Following the success of Bloom, Allyson was invited to participate in the local version of Dancing with the Stars. What began as a one-time experience turned into a true calling. Falling in love with ballroom dancing, she opened her own studio in 2013, where she led teams to competitive victories while fostering an environment built on camaraderie, confidence, and genuine human connection. Her work in both business and coaching strengthened her natural leadership skills and deepened her commitment to helping others achieve their goals.
Together, these experiences paved the way for Allyson’s transition into real estate—a profession that merges her entrepreneurial instinct, her love of people, and her talent for guiding clients through major life transitions. She is proud to be joining the renowned Karen Karpman team at Sotheby’s International Realty Québec, a team that brings signature warmth, care, and professionalism to every client they represent.
Whether you are buying your first home, transitioning into a new phase of life, or selling a cherished property, Allyson approaches every transaction with heart, expertise, and a genuine interest in the personal story behind each move.
Allyson looks forward to helping you reach your real estate goals with confidence—and with someone in your corner who truly cares.
