Mary worked with each of our three children throughout the college application journey. Each child possessed unique preferences concerning the type of college they aspired to attend. She surpassed expectations from the very beginning until the final decision was made. Her support encompassed essay writing, resume crafting, application guidance and every facet in between. Mary ensured that the process was seamless and stress free. As an additional benefit, they are all in the right place and have had extraordinary college experiences. She is truly exceptional.

My daughter connected Mary from the very first Zoom in Grade 10. Not only is she warm and personable, she knows this process inside out. While I met with Mary at the beginning of the process, she and my daughter had numerous meetings where so much was accomplished. Mary always filled me in on their process - and was always just a phone call away. My daughter had tremendous results, and I owe much of her success to Mary's guidance and wisdom.

Distance did not hinder this process. Mary was always available via phone, Facetime, or Zoom. Her accessibility sets her apart from other advisors - as well as her knowledge of this complicated and stressful process. My son worked very well with Mary and listened to her guidance and advice. I was impressed with her help in developing my son's essay - which was amazing. Without her help, my son would not have gotten into his chosen colleges. Mary is strategic in her approach and offers insight that really made the difference.

My son used Mary as his college advisor during his junior year and not only did she assist with picking the perfect college for him, but the most amazing major as well. Her patience, expertise, strong skills, and personal demeanor made this stressful process such a success for my son. Her informative meetings with both my son and me kept us at ease and well prepared so that there were no surprises. I truly believe my son is happy and succeeding at college because of Mary. I highly recommend her to anyone starting this process.

Mary came highly recommended by neighbors in my community. She assisted my children during their most stressful time in high school. She has a wealth of information on colleges across the country and helps your child find their perfect fit. She communicates very well with high school students, has a calm demeanor, and focuses her attention on your child. Mary seamlessly guides you through the college application process and will set a timeline of your child responsibility to compete by her next visit. Mary will ease your mind and lessen any stress that comes along. Her professionalism, knowledge , and commitment are highly admirable. So much so, that I extended her contact information to many friends. I highly recommend Mary to assist your child's college search journey!

My son attended a Yeshiva high school in northern NJ, where college advisors were available. While this service was available, there was no comparison to the 1:1 attention he received from Your College Pros. Every question and concern was answered with expertise. Mary and Greg  have a great system that works so well with young people. I never had one worry during this process, thanks to Mary and Greg.
