About Dr. Nicolau

Philosophy of care

I feel that patients deserve the best care. A multi-disciplinary approach is imperative to this. Regardless of what field of medicine, from nursing staff to different types of physicians, we are all on the patients' sides, striving to get them better and providing the best care they deserve. 

Why I entered medicine

Since I can remember, I was always interested in the sciences, excelling at them in school. In college, I took a course in physiology, which focused my passion for science towards life sciences. In short, surgery is a life science which encompasses physiology, pathology, and medicine. Together with the importance of good rapport and bedside manners, surgery allows treating the patient as a whole. Helping patients, with a focus on treating them as individuals, is my passion, and knowing this I ensure great care.

Personal interests

I enjoy photography, trying new restaurants and foods, cooking, going to the beach, traveling throughout the world as much as I can, and learning about new technologies involving medicine and health sciences.

Ratings and Reviews

About Our Ratings and Reviews

About our Survey

Our physicians and advanced practice clinicians (CRNPs and PA-Cs) are among the nation's best. That's why we show you patient satisfaction ratings and comments so you can read about and get to know our providers through the eyes of their patients.

To ensure our ratings and comments come only from verified patients, we work with NRC Health, a third-party organization. NRC Health sends patient satisfaction surveys on LVPG's behalf following an office visit or procedure. They ask patients about their impression of the health care provider and the doctor's or advanced practice clinician's communication skills.

What is included in the star rating?

Star ratings are based on a scale of 1-5 stars, 5 being the best. The rating includes responses to these provider-related questions:

  1. Physician Communication Questions
    1. Did this provider give you enough information about your health and treatment?
    2. Did this provider give you easy to understand information about your health questions and concerns?
    3. Did this provider listen carefully to you?
    4. Did this provider seem to know your medical history?
    5. Did you trust this provider with your care?
  2. Overall Provider Rating Question
    1. Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?

Why don't all doctors or advanced practice clinicians have a rating?

In order to have enough data to measure and compare, a health care provider must have at least 30 completed patient satisfaction surveys. Surveys are included for a period of 12 months from submission.
