I love this podcast I just found through the host’s appearance on TCG! Her voice reminds me so much of Kathy Bates as Jo Bennett on The Office!
Sheryl, I absolutely love the show. You are so kind, down to earth, and capable. Whenever I hear your voice I envision Reba McEntire circa 1990 Tremors. 💕
Mac is wonderful and I could listen to her all day, but so many episodes with Nancy Grace, who is so disrespectful to any subject she is not educated on. Cringe.
Sheryl McCollum has IT! She is a generous host to her guest speakers and nails the emotions of her audience.
The title got my attention. Is there anything Mac can’t do? CSI, Director, HOF, Mother, Wife, Friend. I admire her and must read her new book.
