We are business-building investment partners.
Parkstone Growth Partners was founded in 2017 to provide business owners with an alternative to selling their business to traditional private equity. We invest in and help operate entrepreneurial businesses in the healthcare, consumer and insurance sectors. Our partner companies are either seeking capital and expertise to grow, or seeking values-driven new ownership to preserve and build upon a founder’s legacy.
Our hands-on approach means that we will take operating roles inside of our partner companies as needed to achieve our shared plans, including as CEO when appropriate.
We bring decades of shared private equity and operating experience across numerous companies and business situations to each partnership to achieve mutual success.
