Qualifications & Experience

I'm a patient and knowledgeable online math tutor, with 11 years experience. My passion is teaching students who are struggling in math, and giving them a foundation and confidence so that they can succeed in math. I have over 10,000 hours of tutoring experience, and tutor students all over the country. My subjects are Algebra 1 & 2, Geometry, and Common Core Math levels 1-3 (including Honors classes for all subjects). I also tutor PreCalculus, ACT math and SAT math, but only with established students.
My former career was in molecular biology research at Johns Hopkins and Duke Universities. I began tutoring as a volunteer for under privileged children and adults, and that experience has helped to hone my skills to quickly detect deficient areas, so we can work on those to build a foundation of understanding.
My hours are 1-11pm M-F Eastern time with some weekend availability.

TESTIMONIALS:

Awesome and Accommodating
Cristl has been great at helping my 14-year-old daughter with advanced algebra and geometry. She is easy to understand, super personable, and very accommodating, especially when we've needed her last minute!
Sherry, 7 lessons with Cristl

Cristl is definitely a 5 star rating!
She helped my daughter with Geometry, and told me that she is very good at explaining topics and is very clear with her explanations. After today's first session with Cristl, my daughter has confidence to do the Geometry homework. My daughter likes to have Cristl to help her out so she can do better on her High School Summer Geometry Class.

Experienced and Patient Tutor
Cristl helped my daughter is Algebra 2 in April 2019. The lesson covered parabolas. After the first hour, my daughter felt confident about the lesson, and suggested she would like to collaborate with Cristl again for assistance in Alg 2, and even for future math classes.

Amazing Tutor!
Cristl is THE best tutor! My child began struggling with honors Algebra I in 7th grade and I was really,really desperate for help. After searching Wyzant for tutors, I was ever so lucky to find Cristl! Not only is Cristl patient and kind, she’s an incredible tutor. In 7th grade my child went from hating math and barely getting C’s to receiving A’s by the end of the year. Cristl is not only a fantastic tutor but she also builds confidence. Cristl has tutored my child for the last 5 years in many subjects including Honors Algebra I, Honors Algebra II, Honors Geometry, Honors Trig/Precalc, AP Engineering classes, AP Statistics, Honors Chemistry, AP Physics,SAT Math and some AP Calc. My child went from hating Math in 7th grade to being accepted to Mu Alpha Theta in high school, graduating in the top 10% of the class and pursing an engineering major in college. What makes the experience even more amazing with Cristl and the difference she made in my child’s life? ALL tutoring was done online as we live several states away. Even though Cristl had never met me or my child in person, Cristl was there for my child every step of the way to tutor and build confidence and she did it all online. It’s almost impossible to find the right words to thank someone like Cristl who had such a positive impact on your child’s life; we are forever grateful and thankful to Cristl!

Wonderful!!!
Cristl is just wonderful! She explains things in a manner that my child understands and retains. ;-) She has been so helpful to us this year! We couldn't have gotten through geometry without her.

Smiles after 1 session
So relieved to see smiles on my high school junior’s face after 1 session of PreAP Algebra 2 with Cristl. She really likes Cristl’s approach and style and finally understands what her teacher has been teaching. Planning on sessions with Cristl until school is out in May. #godsend #happymom

Great math tutor
My daughter has had many math tutors over the years, but this was the first online lesson she has had. She love it! She said Cristl was great and went above and beyond to help her understand everything. 5 Stars!

Thoughtful & knowledgeable
Cristl was able to make my daughter feel comfortable discussing where she is struggling in Math. In order for her to build back her self esteem, you have to go back to the foundation and this is just what Cristl has done. This is just the beginning but she took on the challenge of helping with a short window of time. I wish I had found her much earlier!

Very knowledgeable precalculus tutor
My daughter REALLY liked Cristl. She explained the precalculus topic so well and and made it so much easier to understand. We look forward to using Cristl again in the very near future.
