What Gentile Holloway O'Mahoney & Associates does

Gentile Holloway O'Mahoney & Associates, doing business as Gentile & Co., is a privately held, founder-owned landscape architecture, land planning, and environmental consulting firm chartered in 1988 in Jupiter, Florida. The firm provides an integrated suite of professional services spanning visioning, master planning, site planning, amenity design, hardscape design, LEED-certified sustainable design, development entitlements, permitting, ecological compliance, vegetative assessments, and adaptive-reuse environmental projects (such as landfill-to-park conversions). It serves both public-sector clients (municipalities, fire-rescue facilities, public parks) and private-sector clients (luxury residential estates, golf clubs, mixed-use marinas, institutional campuses) across South and Central Florida, with selected project work extending into Georgia, Mississippi, North Carolina, Costa Rica, and the Bahamas/Caribbean.

The firm's core technology is its domain expertise in Florida's coastal and inland environmental regulations, zoning, and land-use policy, supported by 12 LEED certifications and the FASLA National Leadership designation held by founder George G. Gentile. It operates as a single integrated professional services practice rather than a productized or platform model — services are delivered through direct project-based engagement. The firm has completed more than 500 projects over 35+ years and maintains a portfolio spanning master-planned communities (e.g., the 2,050-acre Abacoa Greenway), institutional campuses (Max Planck Institute, LEED Gold), luxury residential (Ritz-Carlton Residences, Old Palm Golf Club), and civic identity projects (Jupiter Gateway).

Revenue is generated through quote-based, project-based professional services fees. Pricing is not publicly disclosed and is obtained through direct engagement via website contact forms, phone, and email. The firm relies on direct enterprise/government sales and professional network referrals rather than channel partners, resellers, or digital marketing. Customer segments are split between private-sector luxury/commercial work and public-sector government/civic projects, with additional institutional and environmental/conservation engagements. The company has no disclosed revenue, no funding rounds, no investors, and no parent or subsidiary entities.
