No. Dennis is owned by Apex Service Partners, a private-equity-backed home services rollup (Alpine Investors / Partners Group / Apollo Funds (minority, 2026)). The local name was kept after acquisition.

Is it safe to hire Dennis?

Ownership doesn't determine the quality of the technician. It does determine the sales process. Ask for a written quote, decline same-day pressure, and compare with a verified independent.

What this means before you call

The name on the truck is not the owner. In investor-owned home-service groups, the price book, the sales process and the financing offers are usually set centrally, not at the local office. What to check before you sign →
