I like him very well I had went to another hospital before him and didn't like the doctor at all but with him I feel comfortable

02/19/2026

He's a real nice guy and wants to get the right diagnostics and not just force something on you.

02/19/2026

Excellent care and takes his time with you.

02/18/2026

First impressions were very good

02/17/2026

He really cares about his ok patients and is very thorough plus he takes his time and listening to their concerns and talks to them about their concerns and explaining every thing.

02/16/2026

Timely appointment. I find him to be professional and mindful regarding my health issues. I have confidence in him. He listens and explains well. Excellent bedside manner.

02/16/2026

He takes the time to listen to your concerns and issues and will offer recommendations for methods or next steps to stay ahead of heart disease and keep it in check. He is absolutely the very best!!!!!

02/13/2026

So easily to understand the concerns and the proper steps to be taken.

02/11/2026

Very caring and kind. Explained findings very clearly.

02/11/2026

Hard to change cardiologist,

02/09/2026

He addressed our concerns. He cared and friendly.

02/08/2026

Didn't listen. Didn't explain things. I felt very dismissed with asking questions.

01/31/2026

Learn a lot.

01/28/2026

He is wonderful

01/22/2026

Dr Janeira is a great cardiologist and always takes time to explain everything that I need to do for my health

01/22/2026

Covered everything in full during visit

01/21/2026

Dr. Janeira is the best. Has great bedside manner and truly cares for his patients.

01/20/2026

This was my first appointment, very attentive to my concerns.

01/16/2026

He appears to be good doctor, but as a heart physician, he talks 1,000,000 miles a minute and always in a big hurry and I feel like I have to talk just as fast and remember quite quickly to ask questions before he cuts me off to go out the door. I am trying to trust in him to not worry before my upcoming major back surgery and also my future with my cardiovascular health. I’m sorry, but that is how I felt since my first appointment with him. It may be because I’m worrying too much and as he said, I’m good till I’m 80 a couple years back, but I do have mild conditions.

01/14/2026

There dr was easy to understand and informative showing me on a screen the results of my heart scan.

Dr. Janeira uses his experience to help us to improve in our health condition,

11/12/2025

Clear, consider, but speaks at your level. He adjusts his speech for your level.

11/12/2025

I feel like he considers my overall health wants and needs and considers all my health issues when presenting options. Not for just one issue, but all of them in concert as a whole system, and not just their singular sliver of the story. I am more than just one 'condition'. Too many doctors don't even consider that I have more than just their one specialized health concern. They are offering a single brick, and it has to fit into a building project. They brick is not the only piece in the tower. Even if they feel theirs is the most important piece: it still has to fit with ALL the others.
