Hi! I'm Chelsea DiMarzio, co-owner and COO of LD Expert.  I am a speech language pathologist that has been serving students through telepractice since 2014. I have Bachelor's degrees in Psychology and Communications from Walsh University and a Master's degree in Speech Language Pathology from The University of Akron.  I love working with and advocating for students, especially those who struggle with language and literacy. I deeply believe that words matter, and that the personal relationship with each student, family, and school team is the key to building up that student's confidence in his or her ability to work hard and tackle big challenges.  I've been fortunate enough to work with hundreds of students in various school systems across the country through telepractice. This experience has helped me better understand the real challenges our students face, but also to see the very big potential each student has when they know the people closest to them believe in them.

Hi! I am VIcki Landolf. I was raised in a small shore town in the southernmost tip of Ocean County New Jersey. I taught for 18 years in the very school that I attended alongside teachers that had not only me as a student, but my four children as well. One of the highlights that occurred in NJ was that my 4 children, my husband, and myself all received our 2nd degree blackbelts in Tae Kwon Do. However, in 2007 we packed up and moved to the mountains of North Carolina. Here I taught 11 years before retiring. I now spend my time as a floral manager in a grocery store making floral arrangements for customers. I have been married for almost 33 years and enjoy the company of my 3 dogs.

Hello! My name is Belinda Sinopoli. I am certified in Elementary Education and as a Reading Specialist in the state of Massachusetts. I have been teaching for almost 20 years! Since childhood, I had wanted to be a teacher, and decided to pursue a Master’s Degree in reading from the American International College due to my brother’s struggles with Dyslexia. My undergraduate degrees are from Berkshire Community College and Massachusetts College of Liberal Arts. I currently work full-time as a reading interventionist with students in grades K-6. I have tutored students from grades 1-12 in phonemic awareness, phonics, comprehension, and writing skills. I am certified in Fundations, Wilson Just Words, and Wilson Level 1, and I have been trained in other reading programs, such as Keys to Literacy and Heggerty. I have taken several workshops and classes on how to teach students of varying abilities. I love teaching, and I love helping students succeed in their learning. I tailor my lessons to meet each student’s individual needs. I am excited to work with your child, and give him/her the skills needed to succeed.

Hello!  My name is Tim Burk, and I am excited to be a part of the LD Expert Team!  My passion is to help students move from survival to competence in their academic subjects, and share with them how fun and fulfilling learning can be.  I have a B.A. in Music Education from Northwest Nazarene University, and an M.A. in Music from Seattle Pacific University.  My primary instrument is Trombone, which means I am interested in how things work, and basically any subject (just try me).  I was a substitute teacher for a number of years, pursuing higher education in various subjects, and have experience in helping students gain understanding in all the K-12 academic subjects. Because I’ve been fortunate to spend part of my career in various classrooms as a substitute, I was able to learn how to quickly develop meaningful relationships with students in order to teach them in engaging and flexible ways in all subjects. It matters to me to meet each student where they are at and build from there. I look forward to helping your student gain confidence in Iearning!
