With the necessary skills, and with hard work, "I got into honor classes and my GPA went up, and I just kept going on until my senior year."

While she did well in high school and planned to attend a four-year college upon graduating, due partially to financial reasons, she instead chose to attend Northern Essex Community College in Lawrence. She said it was a decision that tested her faith.

"I kind of lost faith, there," she said of attending the school. "I questioned myself and I questioned God."

Yet, "in the end, God had a plan for me, which was to go to a two-year college, get prepared, then transfer to a four-year college and achieve my goals," she added.

"At the end of the day I think my faith got stronger because I feel like I'm now closer to God."

She transferred to Merrimack College, from which she graduated this year summa cum laude with a degree in Child, Family, and Community Studies with a concentration in "Teacher Licensure Early Childhood Pre-K-2."

Graduating with such high marks was "very hard work," Mercado said, laughing.

Now, she works at the Lawrence Early Achievement Partnership (LEAP), where she works with pre-school students.

She's been offered a Kindergarten fellow position at Community Day Arlington School in Lawrence, and will start there in August.

"I always said that you need to be a special person to be a teacher. You need to have that patience, you need to have that love inside of you in order to be a teacher," Mercado said, adding that she loves her job.

"It doesn't matter where you're coming from, as long as you work very hard for it and you stay focused on your goals you will definitely achieve them," she said.

Mercado's story is one that the Archdiocese of Boston Catholic Schools Office hopes to see often repeated.

"The Catholic Schools Office is planning on how we can work with our schools and support them to create opportunities for Hispanic students. We most work hard to open the door to thousands of students like Yannelly," said Sister Barbara Gutierrez, SNDdeN, new director of enrollment at the Catholic Schools Office, June 14.

"Their stories are seeds ready to be sown; we (Catholics) are the earth that would help them to germinate and become inspiring stories-- or not," she continued.

Sister Barbara, previously the Director of Admissions at Notre Dame Cristo Rey High School, knows Mercado well.

Mercado worked as her assistant for a time while she was a student at the school, and said she learned much from Sister Barbara.

Sister Barbara "helped me tremendously," said Mercado, noting that she taught her computer skills and receptionist skills, among other things.

"She helped me more than you could ever imagine," she said.

Sister Barbara later attended Mercado's graduation ceremony from Merrimack College, after Mercado presented her with one of her four tickets to the graduation.

"I do have siblings, however, I felt that this was a very important event in my life, and I wanted people that helped me achieve that to be there," said Mercado.

For Sister Barbara, "that was one of my best presents."
