Parkstone Growth Partners

Founder Lou Marinaccio is the sole decision-maker on new investments, drawing on 18 years of deal experience as a Partner at North Castle Partners. Partner Dylan Kindler, who joined in 2018, supports sourcing, due diligence and portfolio operations. The firm’s website lists no additional investment committee members.

Parkstone explicitly markets itself as an alternative to traditional private equity. Its partners take hands-on operating roles inside portfolio companies — including as CEO or President — rather than installing third-party executives. Marinaccio currently serves as CEO of portfolio company Physical Therapy Billing Services, and Kindler as President.

The firm targets entrepreneurial, founder-led businesses in healthcare, consumer and insurance sectors. Known investments span revenue cycle management, autism therapy, dental service organizations and adolescent behavioral health — all lower-middle-market service providers, primarily in Florida.

Parkstone appears to operate exclusively through direct control investments, with no public indication of fund-of-fund commitments or LP stakes in external private equity vehicles.

The source of Parkstone’s investment capital is not publicly disclosed. The firm does not reference a parent family office or a disclosed LP base, and its AUM remains undisclosed.

Parkstone is a manager of external private equity assets, not a family office. Unlike a single-family office that invests a single family’s wealth, Parkstone’s capital sources are not publicly tied to a specific family, and the firm markets itself as an investment manager rather than a private wealth vehicle.

The firm has not publicly disclosed a co-investment program or any history of syndicating equity alongside external general partners. Its known transactions appear to have been wholly controlled platform investments, including the 2018 formation of Parkview Dental Partners with Bayview Dental Partners.
