You will notice they don't list the phone numbers. I would be very surprised if they would take a call from an individual. Now if I was a lawyer calling along CEO/CFO of a publicly traded company like GNBT or Donohoe calling, stating I needed to ensure they were aware of recent and future already publicly announced events , then maybe I take the call. Probably not. They work for the OTC.
Understand the MM's of most OTC stocks know nothing about the companies. They each have multiple companies to deal. Most of these companies are tiny or outright scams. Most do not trade on fundamentals. For the most part all the MM's see are orders.
