Very pleasant and professional. Also takes time with patient to address their concerns.
Compassionate in His Care
Dr Katsikas is thorough, explains treatment and findings clearly and is compassionate in his care. I have been attended by him for over 15 years and he is consistent in his care.
Thorough and Considerate
He was very nice while being efficient. His explanation of suggested tests and possible next steps was clear. I did not feel rushed during the office visit. I think anyone being seen by him would feel confident that he was thorough, considerate, and would provide good care.
