Wow, time flies when you are having fun. Seriously, this has been a wonderful transition for us and really appreciate all you have done to to turn a difficult situation into a positive one.
Gibson S. - Manager
Thank each of you for the hard work for our mutual client….This VB transition was well thought out and well executed and I really appreciate your hard work over a period of weeks and months.  A lot goes into a carrier change, especially when it involves one on one education and this team made it as seamless as possible.
Kristen - Benefits Broker
I want you to let you know how much I appreciate the excellent service you provided.  On a day that you were scheduled to be out of work, you took my call to your cell phone regarding a distraught employee who realized she had been scammed and compromised her csONE debit card. You had the card cancelled within 5 minutes! Outstanding customer service once again. Many thanks!
Maura S. - Benefit Specialist
I really appreciate help that csONE has provided us. I just shared at a staff meeting how helpful everyone has been, and how easy it has been to communicate with everyone! Thanks again!
Lisa C. - Manager
I would absolutely recommend csONE as a TPA for any District or employer. Having gone through a full year of working with a TPA that was unable to do the job successfully, csONE has been a true breath of fresh air and relief to the District as well as all our employees.
Amadee D. - District Manager
csONE service and competency is the best I have worked with. They are worth double the price paid to any other HRA provider. In my career, I have had to fire two other HRA providers mid-term for incompetency and csONE came to the rescue. With minimal stress they straightened out the past errors and made the process painless. I have one client who is offered free HRA services from an insurer and they insisted they stay with csONE.
Mike K. - Broker
csONE is absolutely the best to work with! Great customer service. Kudos to your team.
