She is fortunate to have explored various career paths such as working in the corporate world as a product developer, co-owner of a chain of salons in New York City and she opened a catering firm in Europe.  The journey of life has taught her the lesson of self advocacy and she feels this is deeply ingrained in her beliefs and how she inspire others. She believes that one must always work towards improvement and growth. Taking calculative risks and creating a community helps direct us towards greater success.

She has worked across K-12 classrooms and is passionate about uplifting them from where they are.  She instills strong values of higher education and helps other aspire to soar beyond their comfort zone as growth lies at the edge of discomfort.


Her personal life has greatly impacted her professional career. She has been fortunate to start her educational journey in New York City schools under a full scholarship from the State. She served inner city students and the international network of schools as an ENL educator.  Sonal raised her daughter as a single mother which enabled her to teach in Long Island, Dutchess County and Westchester County school districts. While her husband worked on his medical practice internationally,  she was able to share her best practices via professional development in private schools, collaborate with IB schools and advise on State school policy work in Gujarat, India.  She has worked as an adjunct at Hunter College within the Curriculum and Teaching department along with providing professional development across districts in Westchester County and Dutchess County. Since 2019 she has been closely affiliated with NYS TESOL volunteering my time during annual conferences to support various outreach work from the network. 


As an educator she aspires to create the best opportunities of success for ELLs through the implementation of effective and inclusive academic programs, an academic environment which fosters growth and assimilation all while keeping the heritage advantage of our ELLs. She truly believes that rich cultural diversity represented by ELLs, their stories and life experiences have so much value which inspire passion for success. 


Sonal believes her commitment to providing education rights and her love for advocacy fans the fire of bringing justice and voice where it's needed. She has faith that together as a community we can help our students and families harness success with the right exposure and guidance.
