The business was founded in 2003 by Steven Sim in Knightswood, and quickly grew in popularity leading Sim to open a further two branches in Bearsden and Milngavie.
In 2017, Sim and Son purchased the former Temple Anniesland Police Station, which was refurbished into a contemporary funeral home and head office.
It is the fourth Scottish business to join Funeral Partners.
Sim said: “I want to maintain the high standards the Sim and Son name has become known for, and Funeral Partners is the right family-oriented network for the job.
“Funeral Partners allows Sim and Son to continue operating as it always has while investing in it and supporting with administration processes.”
Sam Kershaw, CEO of Funeral Partners, added: “Steven and Shona have built an excellent reputation for high standards, quality of service and first-class facilities in Glasgow West End. Their business values and principles align well with our own, making them an excellent addition to our family of businesses.
“I am delighted that both Steven and Shona will continue to work within the business together with their well-respected team. We look forward to supporting and investing in Sim and Son.”
