What We Believe

Better customer service begins with a consultative approach

We can’t serve your customers if we don’t know your business. We utilize a consultative approach so we can create the best plan for you.

Consultation to build your answering service plan

We start each engagement with a consultation to identify your business needs, industry specifics, financial parameters, message delivery requirements, etc. Then we create the answering service plan that will fit your needs.

Quality control ensures satisfaction for every customer

Delivering professional service to your customers means holding our employees to the highest standards. Our employees undergo rigorous ongoing training to ensure they are well equipped to represent your brand.

Weekly reviews & accuracy checkpoints

Every agent is evaluated weekly on three random calls to comply with MLT’s quality assurance program. The program checklist features 16 specific aspects of handling each incoming conversation.

The performance checks don’t stop there. After each message is taken, it is reviewed once more by our dispatch team for accuracy. Then, our dispatchers ensure the message is properly routed.
