The booking process and communication with Stephanie was great and the changes I requested were not a problem. I have booked a number of events with Karstens and it’s always an easy process.

I just want to pass on a heartfelt thank you for hosting the COS training last week for the 4 day event. Sam, Kira and Hannah were so accommodating and helpful to every request or question I had for them.

Natalie van Winckel

Manager, Education and Virtual Health Services

Over the past four years, I’ve presented education programs at Karstens venues around Australia and the support from their team has been second-to-none. Everything is always set up and ready to go, so I can walk in, present, and focus entirely on my program with no stress. Their professionalism makes my sessions run smoothly and look even better, which is always noticed and appreciated by attendees. After presenting in venues all over the country, coming back to Karstens genuinely feels like returning to a second home.

Thanks so much for reaching out – everything was great! Phil and Shay (pardon any spelling errors) made everything really easy and seamless and we also loved meeting Stephanie on the first day who showed us all the rooms etc. All the conference guests really liked the open and bright spaces you offered – thank you so much for everything!
