STEVEN L. BLUMLEIN, MD REVIEWS

Dr Blumlein is a real "people" doctor. He is compassionate, understanding, a real listener and someone who generally cares. He makes sure that you understand the information that he is telling you. He even does this with your family. Makes everyone's life a little easier. I have been seeing Dr Blumlein for 13 years now and I am so glad I found him.

It is actually my husband who is a patient of Dr Blumlein's. My husband unexpectedly had a coronary episode which was very scary. Lucklily for us Dr Blumlein was on call. He listened, assessed and diagnosed his problem in a very short time. From a spouse's point, he is very caring, informative and excellent in his field. I would highly recommend him to anyone in need of a cardiologist.

This was my first visit to see Dr Blumlein. What an AMAZING experience. He was very detailed, explained my condition better than my prior cardiologist out of state and also changed a medication that should have been changed before. Very glad I found him. Dr Blumlein, if you read this, THANK YOU so very much.

DANIEL P. O'NEILL, MD REVIEWS

Dr. Daniel O'Neill, M.D. Is a very experienced and caring cardiologist. I have been seeing him for five years, and he always listens to my concerns and recommends appropriate next steps. We always make decisions together. This is the first time I have ever placed a post on Google, and I would highly recommend Dr. O'Neill for all your cardiovascular issues. I would definitely give him all five stars!

Dr. O'Neill is warm and approachable. He answered all of my many questions and made me feel comfortable. His office staff is efficient and I've never been left waiting past my scheduled appointment time. Another plus, his office is conveniently located to my home.

Dr. O'Neill is very good. He checks all aspects of your problem and authorizes the proper tests and medications. He has a sense of humor and is concerned about your personal life as well as your physical needs. Good doctor and I highly recommend him.

PETER Y. HUI, MD REVIEWS

Dr. Peter Hui is beyond outstanding. He has been my cardiologist for 15 years, and he has managed my case not only with the best and most thorough clinical care imaginable, but he is kind, compassionate, and committed to his work. What makes him so great is that he stays right on top of your case, and anytime there is a need for care, he moves quickly, efficiently, and completely to address and to solve every aspect of the issue — all while taking the time to fully explain to you in understandable terms what is going on and why he is recommending the treatment that he prescribes. I trust him implicitly and I feel 100% safe in his hands — and with something as important as my heart, that is a very welcome and secure feeling. He is the best of the best, and if you are lucky enough to have the opportunity to get into his practice, by all means, jump at that chance. Thank you for everything, Dr. Hui!

Dr Hui was well informed about my issues when I arrived, he listened carefully to my questions and concerns. He then laid out and scheduled the next steps for my treatment. I am very satisfied with his knowledge and skills.

Dr. Hui explained everything in a manner a person could understand and did not rush the process. He was present during the entire appointment, and made sure all my questions and concerns were addressed.
