Consistent Experience Every Time!My wife and I have been coming to Northern Horizon Dental in Alcona since 2019 and the level of customer service... from the time you check in, to the moment you book your next appointment is second to none! Denise, Pam and others who have been at the front desk are very accommodating with billing arrangements, appointment changes and reminders. Also, the quality of oral care I've received from Amanda and more recently Treza and Tarlan have been superb! The environment is safe with all the Covid Protocols they have in place! Keep up the good work everyone!read more
