# Mark Kiefer Electrician

**Trade:** Electrical · **Address:** 53 Grassy Pond Dr, Dennis, MA 02638 · **Phone:** (508) 737-5227 · **Languages:** English

**Rating: 3.2/5** (low confidence) — from 1 reviews across 4 sources.

## The honest read

Mark Kiefer Electrician is a small, long-running residential electrical practice based at 53 Grassy Pond Dr in Dennis, MA, operating in this location under the trading name Dennis Electric Co with owner Mark Kiefer at the helm for roughly 19 years per BBB. The Massachusetts state registry independently verifies an active electrician license (#26093) held by Mark B. Kiefer, the strongest fact in the record.

Online documentation of the work itself is thin. The only review turned up in this scan is a single 2023 Google comment calling the electrician "competent and honest," and Google's own aggregate shows 3.7 stars from 6 ratings overall. BuildZoom's permit database, separately, shows 74 permitted electrical jobs on file spanning Dennis, West Dennis, Dennis Port, Yarmouth Port, South and West Yarmouth, Harwich, Hyannis and Chatham — evidence of a real, working Cape Cod electrical practice even where customer reviews are scarce.

Worth asking about before booking: BuildZoom's own license display is confusing and internally contradicts itself, showing the same license number as both "Active" and, elsewhere on the same page, "Inactive" or "no active license on file." The state registry's own verification is the authoritative word here and shows the license active, but it's reasonable to ask to see current proof of licensure and insurance directly. The business is not BBB accredited, and BBB shows no numeric rating for it.

This looks like a solid pick for straightforward residential electrical work on the Cape from an operator with a long track record of permitted jobs, though the sparse review history means it's worth confirming scope, timeline and pricing directly before booking.

**Strengths:**
- State-verified license — active Massachusetts electrician license confirmed by the registry
- Long-running practice — trading as Dennis Electric Co about 19 years per BBB
- Positive review — 2023 Google review called the work competent and honest

**Concerns:**
- Confusing license panels — BuildZoom shows the same license active and inactive
- Thin public review base — one review found despite 74 permitted jobs on file

**Where sources disagree:**
- BuildZoom's own license panels contradict each other for license #26093/000026093: one panel shows it Active in Massachusetts (while noting its own last-verified expiration was July 2016), another shows it Inactive/cancelled via the City of Newton, and a third states "No active license on file" — the Massachusetts state registry independently verifies this license as ACTIVE, held by Mark B. Kiefer, which is the authoritative status.
