I love the automated scheduling with GReminders. I’ve literally spent hours of my day trying to coordinate time for a meeting. Now, I just send out a link to our online calendar and a little while later, I get a notification that an appointment has been scheduled. How easy is that!

Our Dental Practice was plagued with no show patients. We have a pretty long waitlist and it seemed like such wasted time when our dentist and hygenists were not attending to patients. We estimate that GReminders has cut down on our no shows by about 90%!

GReminders has made a huge impact in our business, from scheduling to reminders. We work so hard to get new Prospect meetings, this reduces no show rates dramatically.

Every no show is $250 lost. I am so thankful that I have found this tool for my practice.

Our office is crazy busy and sending text reminders to clients has been great, but with attorneys in and out of the office all day, reminding them of their own upcoming appointments has been equally important.

Very helpful software in reminding my therapy clients that we have sessions. It allows my clients to RSVP and let me know that they are coming. It also reminds them 24 hours before. This has been great in increasing attendance and reinforcing no show policies.

GReminders not only helped us reduce no-shows, but we also noticed a huge improvement with clients showing up for their appointments on time. That was one of the biggest issues in our office.
