Portland Math Tutor

An elite ivy league tutor. Precalculus AP Calculus and college advisor.with professor Lindgren's help I was accepted into John Hopkins. Former LaSalle student

Have been sending my daughter to John's for the past two years (she skipped a grade at Catlin Gable) and she loves it. He is great with kids and has a real knack for teaching. He makes sure to listen to the kids' concerns and helps them excel. Couldn't be happier!

Best high school math tutor ever. Both my children scored 5s on the AP Calculus tests. John is also a great college advisor. Highly recommend.

John has been helping my son out every weekend for about 6 months now. He is less nervous about his calculus studies and has a lot more confidence. Can’t recommend him enough.

John is a gifted tutor who can help you see the beauty in math. He's patient, enthusiastic, and knowledgeable, and he'll help you develop a love of math that will last a lifetime.

John has a great way of connecting with our 7th grader - making challenging concepts digestible without talking down. He’s more than just a tutor, a scholastic mentor to our kid who is as happy to discuss the cosmos as much as algebra. Thank you John!

I’ve worked with John for over 5 years. He helped me discover knowledge that I would’ve never thought that I was capable of understanding, and I am forever grateful for the relationship and mentorship with which he has provided me.

Our son has used him for several years with college level math. John was able to connect with him on a personal and academic basis.it felt like Chase got more help from John than several of the professors at either PCC or PSU. During Covid with remote learning the only option he struggled a lot; He would not have passed some classes without John's tutoring. Now Chase is transferring to Oregon State in Engineering this fall which is in no small part due to John's assistance.

I recently had a math tutor, John and my experience was great! He was friendly, patient, and knowledgeable. He made sure to explain concepts thoroughly and gave me plenty of practice problems to work on. He was also able to adapt his teaching style to fit my learning style. He made math enjoyable for me and I was able to improve my skills and grades in math. I would definitely recommend John to anyone looking for a math tutor.

John is a Master of his Craft, which is Mathematics. If you want to fall in love with this subject & carry it lifelong, along your academic & professional career, he's the one to contact. The conversations are like storytelling & they help make me look Computation from a new perspective at Gaming for Intel, for it's all Math, i.e lots of Linear/Modern Algebra, Calculus & a lot of imagination:)

John Lindgren helped my daughter get As in pre calculus, AP Calculus AB and BC and Linear Algebra. He was our college advisor. Nikki now attends Texas A And M.
Fantastic!

John is a brilliant communicator. I have learned so much from him. He has helped so many with Pre-calculus, AP & IB calculus. The Best!

Professor Lindgren is a life saver. I wouldn't have passed
I near algebra or differential equations without him. He's funny and supersmart.

John was incredibly helpful and supportive to my son through the application process. His insight and guidance was invaluable. He always made time to help and give feedback, even on short notice. My son really enjoyed working with him and became a much better writer. We are very thankful to have found John. Highly recommend!

John is a brilliant professor! My son at Westview scored 5s on his AP AB AND BC Calculus exams. He was also our college advisor. Though Sam had a D, he is now studying computer science at Michigan! He is Brilliant! And funny!
Five plus Stars!

John is a fantastic mathematician who really knows his subject better than anyone who I have had, but he is also a professional writer and poet. Teaching high school and university calculus is easy, but John also taught me how to write, which is difficult, but not impossible. He made my academic experience at Westview enjoyable and I also loved our conversations. I recommend him to any student looking to apply to an elite college.

Forget the cookie cutter establishments. Professor Lindgren is the real thing. From algebra to AP Calculus to advanced University math he covers it all. He also is a professional college counselor. My daughter couldn't have been accepted into Yale without his help. Passionate and dedicated.
Five supernovas.

John is a treasure! Forget agencies. He helped my son get into Stanford!
Oh yes. He’s a brilliant mathematician. Calculus.
Lake Oswego mom.

My 10th grade son has enjoyed working with John. He is an amazing tutor! He is very experienced, patience, knowledgeable and fun.
He did an amazing job with my son and the end result was amazing.

I highly recommend John as a tutor.
Thank you so much for your help!

My son got a little behind with math during the pandemic and we found John through word of mouth. John has helped my son get back on track and is enjoying math again. He made learning math fun! Thank you, John!
