"Trillian is our primary form of internal communication"

5/5

What do you like best about Trillian?

We've been using Trillian over 10 years now, it's been perfect for us - light weight, no bloated features, easy to use, helps us communicate faster and more efficiently than email or phone. Highly recommend. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

The downside is that employees have less face-to-face time and can sometimes misinterpret tone in messages. We’ve had to find new ways to encourage staff to get to know each other better. Obviously, this isn’t really a limitation of the software but more of a broader societal shift, and that’s the only thing I could criticize. Review collected by and hosted on G2.com.

5/5

What do you like best about Trillian?

I like best that this chat is user friendly and HIPAA compliant. It is able to be accessed from laptop, desktop, cell phone; both in office and away from the office. This allows us to set up group messages where we can chat about patients directly. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

The one and only thing that I don't like about this is when you are using a group chat you are not able to buzz anyone to notify them or grab his/her attention versus when it is chat one on one you can select to buzz the recipient to get their attention. Review collected by and hosted on G2.com.

What problems is Trillian solving and how is that benefiting you?

We have one messaging service used by employees and physicians both on site and off-site best part it is HIPAA Compliant. The fact it can be used on your cell phone, your desktop, and laptop. Saves time from walking files down to the clinic as they can be sent safely through Trillion. Can message group of Radiologists and or physicians about patient and they get messages right away don't have to go check email to get message comes to phone just like a text and pops up on computer like any instant message.
