Revenue Maximization Group is a subsidiary of a public company called Nexteligent Holdings from best I can tell.
After several high pressured phone calls from its President, Stuart Miller, our clinic signed up to work with them. We had to an up front fee, and our employees spent dozens, if not hundreds of hours gathering the information requested by Stuart Miller.
What ended up happening is that this company did not, nor could not deliver on the services and refunds it told us that it could deliver.
Stuart Miller flat out lied to us.
In summary, I strongly suggest you look for an alternate company, as we did, to fulfill our needs .
