  1. Amidst all her honors and achievements, Rosita remained a humble farm girl who put others ahead of herself. She learned love, service, consideration, and doing her best from devoted parents. She loved Jesus from an early age and did her best to serve him in every situation.

  2. Sister Rosita was a wonderful neighbor and friend. Fiercely independent, she was a joy to talk with. Her smile, positive outlook on life and people and sense of humor will be missed. Her commitment to health and well-being was evidenced by her early morning trips to the gym and walks around the neighborhood. She would often stop to pull up a chair to chat for a few minutes in the summer when neighbors were around outside. May her sweet soul rest in peace.

  3. Joe and family; my thoughts and prayers go out to you in your time of loss. What a wonderful and fulfilling life she enjoyed. Her service to the Lord is heart warming. God’s blessings upon you. Sincerely; Tom Owczarski Montague class of 1962
