- AMANNAMARIE MEDEIROSNov 26, 20245.0Choose no other! David and Shannon of AJ Dauphin are great as are other members of their team. My husband's family started using this company in the 1960's. AJ Dauphin has provided services (water heater, toilet repair/replacement, faucets, dishwasher, etc. )at my two properties in more recent years including fixing other people's poor work. So, be careful whom you hire! Prompt, personable, patient and skilled: that's AJ Dauphin and Son.
