I was his patient for a long time, every time he said he will do this or do that he always back out of the procedure he agreed to do! I have has Gastroparesies for over 10 years. And he said I have the same thing and I’m ok. Well yea he is a dr so I’m almost 100% that he got top care! I still suffer to this day with nausea, vomiting, severe abdominal pain and low strength. Worse dr ever.

Dr.Dalton is the nicest gentleman caregiver. I am deathly afraid of hospitals&needles.Never mind discussing internal intestinal problems.He put me at ease to explain "ALL"my problems/colitis,the big D, everything.Whenever Dr.Dalton performs a procedure on me,I'm relaxed&confident.Every 1 has been a breeze.His bedside manner&support of his patients while in the hospital are over&beyond.A visit/the Dr.leaves you feeling at ease,like a chat a friend. Thank you Dr.Dalton for ALL you do! Sincerely, Sharon Silvia Patient PS. Let's not forget to rave of his crew,all very helpful.Especially Hope Daggett,NP. very personable,great listener,&fantastic diagnostics skills.Thank You Hope,for your patients with me.

JWD has been my doctor since I was a teenager and he is intelligent, kind, always takes time to talk and listen during appointments. Bedside manner is second to none!

Beware of Steward Medical Group practice. Dr Dalton refused to allow me to see a Podiatrist that was within my health plan but out of the Steward Medical Group. I made several calls and waited 5 days to get an answer regarding my referral request only to be denied. The Office Staff told me I had to go to a doctor within the Steward Medical Group or the doctor would be penalized. Filthy office with dirty smelly rugs and chairs you can smell as soon as you walk in

I have been a patient of Dr. Dalton's for over 20 years. He is excellent. Sometimes the wait maybe long but it is worth it. Spends enough time with you follows-up and he is just a great doctor. They dont make doctors like Dr. Dalton anymore.
