Ruth Griffin is a great math tutor. She has helped my middle school daughter understand algebra, and helped her with some basics my daughter *should* have studied in late elementary school. Ruth arrives prepared with games and plenty of her own material to support what homework and tests my daughter is working on, she arrives on time, she clearly understands what my daughter is going through and explains with patience and grace. I can’t recommend her enough. signed, a mother who has not studied math for over 30 years.
