JULY 2025: l was hoping for tbe doctor's new office to be at the Orange Coast Memorial campus...they didn't realize how busy and how full his office always was I guess. That's okay because he got an office right by my oncologist off of Warner and Euclid in Fountain Valley...beautiful new office. You're such lovely pulmonary doctor to work with! You are great to work with, knowledgeable and have a great bedside manner. Always making me smile.Dr. Singh has been treating me since I had covid a couple years ago and my breathing just wasn't the same but he brought my lungs back to a great place of health... working proactively not reactively! Thank you Dr. Singh for your professionalism, your kind and caring staff are a pleasure to work with JULY 2024 : Star review as there's always room for improvement. Dr. Samarjit Singh is always kind and polite. He makes the time to listen, and truly cares about your best well-being. I usually wait about 15 to 25 minutes to be seen and that's ok because I check emails and they always have great music playing in their peaceful little waiting room. He's also on staff at a doctor at Orange Coast Memorial. I've been a patient of Dr. Samarjit Singh for a couple years and highly recommend him. His staff is pleasant and on point with everything in his front office as well as back office. His assistant/nurses are kind and polite and have great bedside manner. Don't let me forget he's a doctor that actually smiles too. read more

I attended my first appointment today with Dr. Singh for sleep disorder treatment. Dr. Singh and his staff are highly-professional and made me feel welcomed. Moreover, Dr. Singh patiently and methodically explained the nature of my particular issue and treatment plan options. He further explained next steps and asked if I had any questions. As a result, I am highly confident that Dr. Singh will be able to help me. He is a true professional and a gentleman who goes to great lengths to assure his patients.

I wanted to see this pulmonologist because he's considered to be one of the best. Unfortunately, they turned me away because I pay for all of my medical out-of-pocket. My job doesn't offer medical, and I make too much money to qualify for Covered California. Not sure what the issue is if I prepay the entire thing before the office visit. I asked the girl that turned me away if she could recommend anyone, and she abruptly told me no. Really nice. read more

Absolutely smart doctor with big heart. We are lucky to have him as our doctor. Staffs are so nice.

Our team of medical experts referred us to Dr. Samarjit Singh to help my wife with several potential problems with her lungs. Dr. Singh has assembled a staff of very qualified, professional and carrying people. The office is well organized, clean and filled with state of the art equipment. After meeting with us for the first time Dr. Singh ordered blood tests and a CT Scan of the lungs. Dr. Singh is very informative and speaks to you with empathy and answers all your questions. On our second office vist my wife had a lung test done in his office by a very kind professional lady. Then we met with Dr. Singh, I brought results of tests done by other Drs. on our medical team and Dr. Singh reviewed them all and showed us his test results. He explains everything to make sure you understand it. The results were great and we have a plan to follow to make sure my wife does not have any Pulmonary problems. My wife of 53 years is being seen by the best and we highly recommend Dr. Singh and you will find him to be kind, very professional and his staff is just as good. We hope to be seeing Dr. Singh for many years as our Pulmonary specialist and a valuable member of our medical team. read more
