Dr, Grundy comes off as an authority on everything. I saw one of his ads on line about leaky gut and it took forever for him to come around to tell you that he is trying to peddle a supplement that he has created. Sounds like a real grifter to me! Also, the entire time during his long winded video presentation, he can’t help but tell you all of his accomplishments over and over again. There are so many of these people out there now and you really have to be careful!
