Dr. Erdmann is FANTASTIC. I guess i am a skeptic at heart…and when i came in with my initial shoulder issue, i didnt come in believing he could help but i had tried everything. Dr. John helped me a TON. I have been in for back pain, neck pain, pulled muscles, diet issues, etc. He is a pro. VERY consultative and education based in his approach. I have entrusted my 3 kids with him in with various issues and he has helped EVERY TIME!!

Thanks for all you do Dr. John!!
