Rosario spent many years working as a Spanish translator in a hospital settings and wherever her services were needed before settling in to her ultimate life's work, being a mother. When her children were older, Rosario worked for 15 years as a Spanish teacher at Assabet Valley Regional Vocational school in Marlborough. Rose loved teaching and enjoyed all the relationships she made with co workers at Assabet. Rosario enjoyed the simple pleasures in life and was rarely seen without a small dunkin donuts cup. She reveled in making the holidays special for her family and finding the time to lay in the sun during the summer. Rosario loved taking spontaneous day trips with her husband. She joyously accepted the job of doting grandmother, "Abu", two years ago and found her enjoyment in celebrating her children's happiness.
