About this company
Radon & Mold Professionals is an assessment-only firm in Bonita Springs, Florida, run by owner John Cosgrove and inspector Greg Gomez. They do not perform remediation. Their website states this explicitly, and Florida law prohibits the same company from assessing and remediating on the same project. John holds a Council-Certified Indoor Environmentalist (CIE) credential from ACAC and Florida Mold Assessor license #MRSA5. Greg holds a Council-Certified Indoor Environmental Consultant (CIEC) credential from ACAC and Florida Mold Assessor license #MRSA763.
What stands out is the breadth of indoor environmental testing they offer beyond mold: radon testing (short and long term), odor identification sampling, allergen and particle ID sampling, and water damage moisture mapping using infrared thermal imaging cameras, moisture meters, hygrometers, and borescopes. They send samples to accredited Florida labs. They also do post-remediation verification to confirm a remediation contractor's work met standards. John handles litigation cases involving indoor air quality, which is a niche most mold assessors do not serve.
John has worked in indoor air quality since 2004. Greg joined the firm in 2009 after several years doing restoration fieldwork. The company serves both residential and commercial clients across Lee and Collier counties, and they list real estate transactions, insurance claims, and legal cases as regular use cases.

Review consensus
John Cosgrove is named in the vast majority of reviews. Reviewers consistently describe his inspections as unusually detailed, with multiple people noting he spent hours on-site. His reports get specific praise for clear photographic documentation and actionable recommendations. Several reviewers mention John answering follow-up questions by phone after the inspection at no additional charge. Greg Gomez is praised by name for his knowledge, pleasant demeanor, and willingness to arrive ahead of schedule. Mandah Lento, a Local Guide with 168 reviews, calls them a preferred vendor and highlights fast scheduling. Repeat client Liz Hoffmann and repeat client Sopio Quincannon both came back for additional projects.
0 found across 27 total reviews at 4.9★. No negative reviews found. Without any complaints on record, there is no data on how the company handles dissatisfied customers or what kinds of problems might arise.
Every single review is 5 stars across 27 total reviews spanning 2018 to 2026. This is unusual for any service company. One possible explanation is the small, owner-operated model: John and Greg do all the work themselves, so there is no gap between the person the client talks to and the person doing the assessment. The company also occupies an assessment-only niche, meaning they never deliver bad news about remediation costs, which removes a common source of friction.
John Cosgrove (owner, senior inspector -- praised in majority of reviews for detailed inspections, patient explanations, and follow-up availability). Greg Gomez (inspector -- praised for knowledge, pleasant manner, and early arrival). Sherry (mentioned once by Daiva AO Scan, role unclear -- positive context). Doug (mentioned once by Brian B. as inspector -- positive context, older review).
Ask for John or Greg by name when booking. Request a sample report before committing so you know what level of detail to expect. Since this firm does assessment only, they can recommend remediation contractors without a financial stake in the work -- ask John which local remediators he has verified through post-remediation testing.
Keep in mind
- This is a two-person operation. John and Greg handle all assessments, so scheduling during busy seasons in Southwest Florida may require advance booking.
- They cover a wide service area from Marco Island to Punta Gorda. Confirm turnaround time and any travel fees if your property is at the edges of that range.
- With only 27 Google reviews over many years, the sample size is small. The 4.9 rating is strong but based on limited volume.
