For 27 years, Cheryl has welcomed everyone through the doors with a big smile on her face and a kindness that made every day brighter. Her warmth, dedication, and positive spirit have left a lasting impact on everyone lucky enough to know her. ๐Ÿ’š

๐ŸŒ Diversity is part of who we are - and at Greystone, culture connects us all.

At Greystone, we believe that different backgrounds, perspectives, and experiences make us stronger - as individuals, as teams, and as a company. Diversity Day is a reminder that the incredible mix of cultures, stories, and voices within our workplace is not just a statistic; it is one of our greatest strengths.

With team members representing 23 different countries and speaking 13 languages (and counting!), diversity is not just a word at Greystone, it is something we live every day. Every story, every background, and every voice contributes to who we are and helps shape the culture we are proud to build together. ๐Ÿ—บ๏ธ

Today, we celebrate this richness and reaffirm our commitment to fostering a workplace where everyone feels respected, included, and empowered. โœจ

We are also proud to have 105 immigrants to Canada on our team, in addition to our international employees, meaning more than 63% of our workforce brings international experience and perspectives that enrich our company every day.
