I had been to other doctors who could not figure out why I was having a lot of pain in my thumb but Dr. Riggenbach noticed right away that my thumb joint was very loose. He recommended surgery after trying other options and he did a wonderful job! I don't have pain in my thumb anymore and I can't even see the incision scars anymore because of how skilled he is! He's also very kind and compassionate! Thank you Dr. Riggenbach! You are an amazing doctor!
