About Us

Canine precision. Non-invasive inspections. Montana roots.

Montana Owned & Operated Rex – Fully Certified by Bill Whitstine • Serving Montana & Nearby Areas

Montana Mold Dogs was founded to bring the most accurate, non-destructive mold detection solution to families and businesses across the state. Our elite detection dog Rex delivers results you can trust — fast, clean, and without opening a single wall.

Rooted in Dillon, Montana. Trained by the best in the world.

Our Story

Founded in Dillon by Jess Reverie, Montana Mold Dogs was created out of a deep love for Montana homes and a frustration with traditional, invasive mold inspection methods.

Jess partnered with legendary scent-detection pioneer Bill Whitstine at the Florida Canine Academy. After months of intensive training, Rex — a working-line German Shepherd — earned full certification and is now proudly serving homeowners, realtors, contractors, and property managers throughout Montana & nearby areas.

Our mission is simple: deliver faster, smarter, and completely non-destructive mold detection so Montanans can protect their properties with confidence.

Why Mold Detection Matters: Health Impacts of Mold Exposure

Hidden mold can trigger real health issues — especially for families with children, seniors, or anyone with asthma or allergies. Early, non-invasive detection helps protect the people you love.

According to the U.S. Environmental Protection Agency and Centers for Disease Control and Prevention, molds produce allergens, irritants, and in some cases mycotoxins that can affect sensitive individuals.

  • Allergic reactions — sneezing, runny or stuffy nose, red/itchy eyes, skin rash, and postnasal drip.
  • Asthma & breathing issues — mold can trigger asthma attacks or worsen existing symptoms in people with asthma.
  • Irritation — eyes, nose, throat, skin, and lungs can become irritated even in people who are not allergic.
  • Higher risk groups — children, elderly, and those with weakened immune systems or chronic lung conditions may experience more severe reactions, including respiratory infections.
