"I highly recommend Dr. David Jeffrey for his high quality educational instruction in all aspects of chemistry and environmental science. He brings a high degree of content knowledge, coupled with genuine concern and compassion for every one of his students." Craig Tucker, former Head of Science Department, Canadian International School of Hefei, Hefei, Anhui Province, China.
"Dr. Jeffrey is a bright, knowledgeable science teacher who is committed to reflecting on his own practice and continual improvement. Regardless of how well a lab or lesson goes, he strives to make it even better the next time. Dr. Jeffrey is the rare individual who does not automatically become defensive when asked about his pedagogical choices. He makes the time to get to know his students as people, and in turn they want to perform well in his class.
Dr. Jeffrey is also eager to be involved in other aspects of a school. He was an active member of our STEM team that recruited a high-profile scientist to speak on behalf of our school. He is a willing volunteer for committees and came up with creative class options each year when our minimester rolled around. He wrote thoughtful report card comments about his students and was deliberate about giving students the benefit of the doubt.
Dr. Jeffrey is a lifelong learner in the very best sense of the word. Once you interview him, you will have an even better sense of both the depth and range of his knowledge." Dr. Paul Oberman, Head of School at Robert M Beren Academy
Houston, Texas. Former Head of School, Atlanta Jewish Academy, Atlanta, Georgia.
"Dr. Jeffrey’s dedication and concern towards content and student alike, coupled with a compassionate interest in finding innovative pathways to student success, ensure a great educational experience for all involved. Few teachers match the commitment Dr. Jeffrey exhibits as an educator in his willingness to meet each student at their particular starting point and carry them forward in a journey of learning together." Chris Mark, former Diploma Programme Coordinator, Canadian International School of Hefei, Anhui Province, China.
“Dr. Jeffrey is a very intelligent, dedicated teacher who cares deeply for each student. He makes the extra effort to develop crucial student-teacher relationships and also keeps in contact with his students down the road. My daughter, a G10 student of Dr. Jeffery this past school year, mentioned how Dr. Jeffery presents difficult science content in an easy-to-understand visual format while at the same time consistently challenging students to perform their best.” Chris Marionni, Head of EAL, Canadian International School of Hefei, Anhui Province, China.
"Dr. David Jeffrey has been a brilliant source of inspiration and a strong guiding force for me. I was able to get to know each other personally, beyond the relationship between teacher and students.
This was because of his encouragement and dedication to make the class engaging and stimulating the students’ curiosity. I remember his smile and his eyes brimming with enthusiasm whenever I entered his classroom. I respect Dr. David for his passion to lead everyone to success as well. He tried his best to help every single student in his classroom to understand difficult ideas and be engaged with learning, which makes him special from any other teacher.
I strongly believe that education should always make students to gain ‘knowledge’ and fulfillment of what you have when you leave the classroom. When having classes with Dr. David Jeffrey, I never had such a question of “What did I learn today?” Rather, I entered the class with questions about my insights on the previous lessons and went out of the classroom with fulfillment more than satisfaction. The questions remained after the class made me constantly motivated in the class and become a better conceptual learner as an inquirer rather than to memorize the formulas like a machine.
Dr. David is an initiative and always has a positive attitude while teaching us, which made me enjoy the time spending with him to learn.
Dr. David Jeffrey’s passion on his teaching will give a huge influence on my life." Vito Park, former math student, Canadian International School of Hefei, Anhui Province, China.
"Dr. Jeffrey is an extraordinary teacher whose passion for science is only challenged by his desire to help others. It was an honor to work alongside him." Derek J. Bethel, Head of Mathematics, Canadian International School of Hefei, Anhui Province, China.
"Dr. Jeffrey has been an invaluable consultant for chemical contamination assessment and mitigation. He has a thorough understanding of regulatory requirements and a sensitivity to the costs of achieving compliance. Most importantly, "Risk Assessment" provides an EXACT target for compliance and is critical to any financial analysis. I welcome contact to discuss the benefit I experienced." Michael Tansy, CEO, Tansy Development, Santa Barbara, California.
"Dr. Jeffrey is a consummate educator. He brings a passion for knowledge, a dedication to complete and rigorous understanding, together with genuine interest and care in his students. An individual dedicated to both student success and an impeccable ethical dedication, he is a complete professional. It has been a privilege to work with him and I recommend him completely." Mr. Devon Bobowski, Head of Science Department, Canadian International School of Hefei, Anhui Province, China.
"Dr. David is an extraordinary educator with an outstanding range of knowledge, enthusiasm, and professionalism toward science. He possesses a lot of rare and respectful qualities, I am consistently amazed by his courtesy, unique insights, and scientific rigor.
As an undoubtedly talented educator, Dr. David is not only able to demonstrate all the concepts in a clear and precise way, but also effectively stimulate students’ interest in the content and guide us to think deeper and wider. It can be said with absolute confidence that his passion for science had hugely and positively influenced my view, consciousness and learning towards science. I am sincerely grateful to have the privilege to be taught by him." Cher, former Grade 10 Science student, Canadian International School of Hefei, Anhui Province, China.
"It was an absolute pleasure working with Dr. Jeffrey as a colleague. Not only is he incredibly knowledgeable about chemistry, both the theoretical underpinnings and how it relates to everyday life, but he is also a genuinely caring educator who wants nothing more than for his students to succeed. He's not afraid to take on new challenges and work outside his comfort zone — our school needed someone to teach Algebra, and he stepped up to the plate and did an excellent job. He constantly works on refining his craft, with an tinkering with his instructional approach in a way that any good scientist would recognize." Bill Shillito, Instructor of Mathematics, Oglethorpe University, Atlanta, Georgia; former colleague at Atlanta Jewish Academy.
