The answer is really very simple. He had a number of businesses so he can't claim that he was surprised as to what was going on generally. More importantly, he had a responsibility to make sure that the dentists were properly credentialed before they treated patients. And finally, the "smoking gun" is that he had to use his own credentials, knowing that the dentists involved didn't have them. I'm afraid the government will have a strong case against him. I would also be concerned that the dentists will turn state's evidence against him. He needs a really sharp lawyer to minimize the outcome.
REMEMBER THIS IS NOT LEGAL ADVICE
To find an attorney, go to Martindale.com. This is a nationwide directory we lawyers use ourselves to find highly qualified legal specialists in various fields of law. These lawyers are NOT in Martindale because they paid to be included. They are there because they are rated as QUALIFIED by other lawyers in their field of expertise and geographic area as it applies to your kind of case. The process is this: other lawyers are asked to fill out questionnaires giving their opinion of the quality of the work of the law firm that ultimately appears in Martindale. The site is organized geographically and by legal specialty. Consult with two or three and select the one you are most comfortable with. The Martindale listing will have the names of current or past clients. Contact those clients as references for the firm.
Please refer to the JUST ANSWER disclaimer and rule on this site. You have to consult with an attorney in your state and discuss this matter with him or her. THE REASON is that we do not have an attorney-client relationship and the confidentiality that goes with it on this site. Our exchange is available for all to see. Note that this rule is applicable even though I am a New York attorney and your question may relate to NY law.
