Very caring
excellent doctor…don’t need to anything more
He was very good at describing my knee and how everything was looking good
Did not do any surgery yet. Can't give a 5
Very knowledgeable in his field. He is friendly and I appreciated his pre-surgery phone contacts for both of my knee replacements.
Very helpful.
Dr. Tocks has a nice pesonality & as a surgeon he is top notch. I had TKR on 7/23/26 ,by 7/27/26 I startep P/T with a cane only for assistance & a 118 ° flexation. Since then I have 135° flexation,walk well & do most of what I was doing before surgery. Only at a slower pace @ this time.
Very knowledgeable and professional. Prioritizes the needs of the patient.
Phenomenal doctor. Phenomenal, responsive team. My tkr was such a great experience. Highly recommend.
He is excellent!! Second time I saw him him in about 5 years. Really nice guy with a wonderful disposition. Helped me & he’m never know the gratitude I have towards him!! I can walk again on my right knee. Thank u Dr. Tocks!!
