Dr. Stephen has always been an excellent provider for my health, needs and questions. Her response time to me is immediate and thorough. Not sure what I would have done without her and her staff. Forever in her debt.

Yes, the provider was very in-depth on the explanation, provided excellent oversight, and definitely displayed a high degree of competency in knowing what she was doing, put all our questions to ease, and I would definitely recommend her to either family members or people I know.

My experience was great, since I didn't know her before; it was my first time seeing her on the first day. She was an excellent doctor. I'd like to see her for my gastroenterology as well, in addition to being an endocrinologist. I want her for my gastroenterology, and I'm going to talk to my primary care doctor because she referred me to her.

So I just wanted to say that this was a virtual consult visit, so I don't feel fully equipped to answer all these questions because we haven't done the procedure yet, the surgery yet. But initially meeting her and the information she was able to give me in her manner, I'm very hopeful and I was very pleased. But I'm at the very beginning of my interactions with the surgeon, so I look forward to the rest of my treatment.

[redacted] I spoke with Dr Antonia Stephen during an online consultation office visit. She reviewed the issue of a hyperparathyroid adenoma, which was determined from a recent CT scan. She informed me that I would need surgery and made me feel confident that the procedure would help to correct the medical problem.

Dr. Stephen seems very competent and knowledgeable about everything. I feel like I'm in good hands with her, but I don't feel like my thoughts or opinions matter much. I don't disagree with the course of action she has proposed, but I am also not sure if there are any other options available. I have not been asked for my input at all.

I need surgery [redacted] but she was not attentive to my concerns at all. I'm not confident about her abilities and feel very blown off, just another case and not a person.

I felt that she directed her comments to my son instead of to me. I am a competent, well educated, retired attorney And since I am the patient, she should have been talking to me instead of my son.
