We use Henry Schein as our main dental equipment supplier including Dentrix Ascend, support is amazing they’re always available as soon as possible same day or next day. But we pay an arm and a leg yearly. What other companies are out there that do the same but better or even cheaper? We are a pediatrics dental office with multiple offices throughout socal. We get a lot of complains about ascend being slow and staff tends to label their computers as slow.
