My doctor here is Amazing! He is very personable and took his time with me.

Dr. Kadzielski explained the situation clearly and gave us options for how to proceed with care.

Dr. K is an outstanding provider. I have had the pleasure of working for and with many physicians over the past 30 plus years and his care is a knotch above the best!
Southshore - PG Survey


Dr. Kadzielski was wonderful. He spoke with my daughter and made her at ease. He was informative about her condition and what to do about it. He also recommended she get her Vit D checked because her bones look thin. I like a doctor that looks at the whole picture.
Southshore - PG Survey


Dr. K was very quick, really nice, courteous and caring. However, I felt like I had to pull explanations out of him. I told him my symptoms and he jumped to asking me if I wanted to fix it and if I wanted "relaxation". He didn't explain I needed surgery, but maybe assumed I knew? When I asked specific questions, he answered. But he did not offer much information unless I asked.
Southshore - PG Survey


The doctor did not mention any side effects or concerns about the cortisone treatment. However, I asked a nurse and she handed me a fact sheet. I read that and then had additional questions for the doctor.
Southshore - PG Survey


I unfortunately have spent a lot of visits with ortho docs. and Dr K goes above and beyond and makes you feel he is concerned I often recommend him to others

doctor was straight forward in explanation and care---also explained my options
Southshore - PG Survey


I have been to SSO a few times and although dr is thoughtful and explains well the process in general feels rushed. regardless of who we are seeing it just always feels like dr is in a tight time table. I'm sure it's dictated by insurance and I get it, it's just a bummer.
Southshore - PG Survey


I loved Dr Kadzielski. He was excellent. I've been a patient of Dr Ayers for years but went with my physical therapists recommendation for this doctyfor my elbow issue

Dr K was great! My 12 year old son broke his finger - Dr K reset it right there and we went off to cast it in another room. Highly recomment Dr K
Southshore - PG Survey


Dr. Kadzielski, in particular, was wonderful! Not only was he kind and knowledgeable, but he was in tune to the importance of my daughter's return to sports, and his treatment plan reflected his ability to listen and understand her personal situation. That was very much appreciated.

Dr. Kadzielski was polite, informative and caring. This was my first visit and my problem was treated efficiently and has been corrected to this point in time.

Although I waited a long time on this visit; I have not waited in the past, so I was not concerned. I understand that sometimes delays are a way of life.

Dr K went above and beyond he is a. great doctor
Southshore - PG Survey


I have told friends I recommend the doctor.
Southshore - PG Survey


My original appt was with Dr. Marchetti because I had a very positive experience with him two years ago. After he examined me, He suggested I meet with his colleague Dr. Kadzielski. The interactions with both doctors was pleasant, medically helpful, and I especially appreciate that both doctors thought of each other when evaluating my care. This is a good demonstration of the Practice working well as a team to drive top quality patient care. Well done!
Southshore - PG Survey


Very polite & professional. Took the time to listen to my concerns, answer questions & explained what he was going to do to treat my hand. Very friendly & showed a genuine care & concern for me as a patient.
Southshore - PG Survey


The doctor is quite tall and the exam rooms are small. His height is intimidating. I would suggest he sits when talking with patients to appear less threatening.
Southshore - PG Survey


I could not have been happier with my care
Southshore - PG Survey


I have been seeing Dr. K once every few years over a 10 yr period and during that time he has grown in patience and compassion and has also become less hurried.
Southshore - PG Survey


I have and you saw my father.

he is the best.

Extremely pleasant kind & genuinely caring. I would recommend *Dr. Kadzielski to my family, friends & co-workers etc.!
