Meet Tamar

Tamar Lindenfeld received her Bachelors of Arts in early childhood and elementary education as well as in hebrew language from CUNY Queens College. She received her Masters of Science in Early Childhood Special Education from Bank Street College of Education. Since 2010, when she began tutoring, Tamar has been refining her craft in individualized educational support. While getting her masters she realized the reward of incorporating what she knew of special education into her tutoring sessions, and from this her educational consulting began. As her relationships with her clients deepened, her connection to their families grew and so too her desire to help the parent become an active member of the struggle that education (sometimes) can be. Tamar started Chalkdust Incorporated with a dream to provide individualized support to children throughout Manhattan. 


When she is not tutoring, consulting or teaching, Tamar can be found outdoors with her Australian Shepherd. A native New Yorker, Tamar now resides in the East Village and utilizes the parks, museums and cupcake bakeries that the city has to offer.

She feels it is crucial to give students hands on experiences that allow them to explore and to learn about the world around them in an individualized way. When working with children to prepare for G&T testing, it is this school of thought that guides Anna's plans for each session. In addition to teaching pre-kindergarten, Anna is trained in Teacher's College Reading Rescue and has used this training to work with students grades K-2 in literacy. With this work Anna has been able to bring students below grade level to grade level and above.

Shannon Ballou is an enthusiastic, progressive educator who values the whole child. Shannon received her education in Washington D.C. at the Catholic University of America. She taught pre-k for many years and followed a Reggio Emilia approach. She values song, dance, and rhythm when working with our youngest clients. Through her early childhood work she focused on fine tuning her expertise in developmental benchmarks of children from birth through early childhood. Shannon measured student progress by their ability to meet these standards. After teaching pre-k for a number of years she switched over to second grade to see how the work on the front end of early childhood education impacts the end of it, and the overall transition into elementary education. These experiences gave Shannon invaluable insight into ways that foundational skills impact later stages of education, and showed her how to prioritize skills with her youngest students. We are happy to welcome Shannon back to New York where she has returned to school to study at Columbia Teacher’s College to earn a masters degree in literacy.

She uses an empathetic approach to seek an understanding of each student’s mind, life, and world. She then crafts teaching and working techniques that suit a student’s learning needs while also contributing to the development of the whole student. She helps students build confidence, assess the skills and knowledge they already possess, and visualize what they can become. When she is not teaching, Victoria enjoys baking, playing the ukulele, reading, and spending time with her friends.
