For the past three years, I have had the pleasure of working with Mary Callahan in improving her tennis game. She is a very conscientious and fit young lady who thrives for nothing less than perfection in all her endeavors. Her maturity and drive helps her excel in all that she does, and especially helped her either win or lose very close tennis matches for her high school teams. She showed the same motivation, drive, and excellence on her high school dive team. Her caring helped her to enable other players and divers to also reach high levels of excellence. Besides helping others, she also took the initiative to organize practice events, market the programs for her team, orchestrate end-of-year celebrations for her and her peers during the sports banquets, and applaud her coaches for their efforts. Mary is a valuable person, teammate, and has the strength of character to achieve any goal she targets. I recommend her as a person of higher character who is very caring as I see her with her own pet, and her maturity makes her 100% accountable.
