Best-practice hearing care in Bath, Maine — verified.
If you found us through Dr. Cliff Olson's YouTube channel or the HearingUp network, you're in the right place. Riverside Hearing Care is built around the same evidence-based standards Dr. Cliff advocates — and we're the only HearingUp-certified provider in Maine.
Why HearingUp Matters
Not every provider is created equal.
Research confirms that fewer than 30% of hearing care providers regularly follow gold-standard protocols like Real Ear Measurement — despite these being the recognized standard of care by every major audiology and hearing care organization.
The HearingUp network exists to close that gap. Dr. Cliff Olson, AuD personally vets every provider in the network to ensure they are committed to evidence-based, measurement-driven care. Ian Mishler is Maine's only provider to earn that verification.

Owner & Hearing Care Provider · Maine's Only HearingUp Provider
Ian Mishler is a licensed Hearing Instrument Specialist with national Board Certification in Hearing Instrument Sciences. He is the owner of Riverside Hearing Care in Bath, Maine. Hearing healthcare runs in his family — his grandfather, uncle, and father all worked in the industry — and Ian has spent over a decade serving patients across midcoast Maine using best practices.
After years working at other practices in the region, Ian opened Riverside Hearing Care to build something different: an independently owned, patient-first practice where best practices aren't optional — they're the heartbeat of everything we do. He joined the HearingUp network because it reflects the way he has always worked: measurement-driven, evidence-based, and focused on outcomes that patients can actually feel.
Ian serves patients in Bath, Brunswick, Topsham, Freeport, Wiscasset, Damariscotta, and many other communities across Midcoast and Central Maine, and offers mobile hearing care to senior living communities in Sagadahoc, Lincoln, Kennebec, and Cumberland Counties.
Come and experience the difference of what evidence-based hearing care sounds like. We look forward to serving you.

HearingUp certification means you can trust what you're getting.
Real Ear Measurement at Every Fitting
We use probe microphone verification at every single fitting — confirming your hearing aids are programmed precisely to your ear, not just manufacturer defaults.
Electroacoustic Analysis
Every device is verified in the test box to confirm it performs exactly as specified — catching any hardware issues before they affect your hearing.
Validated Outcome Measures
We use validated tools like COSI, IOI-HA, and HHIE/HHIA to measure real-world improvement — not just assume the devices are working.
Structured Follow-Up Care
Our 3-Step Renewal Program ensures you're supported well beyond day one — with scheduled follow-ups, fine-tuning, and counseling built in.
Independently Vetted
HearingUp certification isn't self-declared — it requires a personal review by Dr. Cliff Olson, AuD. Ian is the only provider in Maine to have earned it.
Truly Independent Practice
No corporate ownership. No manufacturer quotas. Recommendations are based solely on what's right for your hearing, your lifestyle, and your budget.
