Meet Lower School's new faculty

Join us in welcoming LS Learning Specialist Caitlyn Tisch and Red Door Kindergarten Teacher Jennifer Lefkovitz.
Caitlyn Tisch joins USN after spending time in the Chicago area where she worked for 10 years as a special education teacher. While attending Indiana University and earning her bachelor's in elementary education, Tisch competed on IU's swim team also. She holds a master's in special education and a certification in autism spectrum disorders. As the new LS Learning Specialist, Tisch will be an invaluable member of the division's student support team. 
 
Jennifer Lefkovitz joins the kindergarten team in the Red Door classroom. Lefkovitz holds a bachelor's in elementary education from Indiana University as well. She has a master's of education as a reading specialist and additional hours studying educational practice. Lefkovitz brings 16 years of teaching experience in first grade to the West Wing and looks forward to welcoming the Class of 2035. 

In addition to new full-time faculty, the Lower School will be supported by a few long-term substitutes due to extended leave. 

In the Blue Door classroom, we are happy to share that Megan Collins is joining the kindergarten team in late November when lead teacher Lynn Welliver begins her maternity leave. Collins will join Blue Door before Welliver departs to ensure a smooth transition. Prior to moving to Nashville, Collins was a kindergarten teacher and team leader at the Hillbrook School in Los Gatos, California for eight years. She earned a B.F.A. in art history and an M.A. in teaching elementary education from the University of South Florida. Collins enjoys painting and swimming, and loves to go on hikes with her husband Joseph and their 9-month-old daughter Hazel. 
 
In second grade, we are delighted to welcome Molly Darr '92 back to Lower School as the maternity leave substitute for Megan Peterson. Darr will be with the class for the first half of the school year. A skilled and experienced teacher, she has taught for a total of 25 years, 17 of those years being in second grade at USN. Prior to joining the faculty at USN, Darr was a special education teacher in a variety of settings, having received her bachelor's in special education and her teacher certification from Middle Tennessee State University. Interestingly, Darr came to USN as a second-grader herself when her mother, Doni Princehorn, became the Lower School Music Teacher. She and her husband Brad have two teenage children, Hannah and Carson '25. Darr’s hobbies include spending time with her senior dog Charlie Newman, volunteer work with dogs at the Williamson County animal shelter, travel baseball, and gardening. She is thrilled to be back in her "home" of second grade.

  • Back-to-school Popsicle Party cancelled

    Mother Nature is not cooperating for our annual Popsicle Party. Depending on which weather app you use, actual and feels-like temperatures are 98 to 101 and higher. Under these conditions, we would limit student activities, so, in the interest of everyone's health and well-being, we are going to cancell our gathering at the River Campus. There is just not enough shade and certainly no air conditioning to bring relief to hundreds of USN families. Thank you for understanding. We look forward to seeing you in a few days for the start of our new school year.
