Thank you again
Oh, that was a good experience with the Dr. Jonathan. No complaints. He's a good doctor.
I just wanted to say that Dr. Knowles is the best. He saved my life. And he's been amazing at laying out everything I've needed to be prepared for. He's been right about pretty much everything. And I entrust him not only with my life, but with anybody else who would need to see a doctor of his expertise. So thank you.
He's a great doctor, understanding, patient, he listens, and I like him a lot.
This was a particularly embarrassing situation for me, I didn't know what to expect. Dr Knowles is incredible he made me feel at ease and comfortable, I was able to express my concerns and he answered all my questions & let me know step by step what we will be doing going forward. He's very knowledgeable, I had a great experience... "AND I WAS WORRIED" ? Thank you Dr. Knowles and staff.. everyone from the front desk to the one who took my vitals was so professional and very nice.
