Staff always so courteous and everyone is always on time

My husband had his second visit with Dr. Kellar on Monday. 4/29. I had come with him to his first appointment since there were some serious issues that we wanted to get the doctor’s opinion on. We were both very impressed with Dr. Kellar in particular - and also all the staff. We already have recommended you Dr. Kellar to dear friends of ours! Maureen Donnelly and her son Joseph who you saw today (5/1) in your office. It is so very refreshing to find a doctor who is so knowledgeable and at the same time so very personable! That is a rarity today!! Many doctors do not give you the time of day - but Dr. Kellar takes precious time to truly listen and ask questions and answer any questions asked of him. The staff members in the office also are very efficient and friendly - which makes it a delight to come for an appointment. God bless you all!

They are so nice there!!!

Best pulmonary office in area

Great experience

Wonderful experience. Loved the doctor and his staff. Very professional and kind. I am so happy Dr. Wilcox referred me to Dr. Kellar.

Dr Kellar was very attentive and spent time with me to ensure all my questions were answered.

Dr Kellar always giving me enough time to explain the disease or problems.

I was pleasantly surprised with the ease of getting an appointment with Dr. Kellar. The office staff are friendly and helpful every step of the way. They explained everything we were doing and why we were doing it. Dr. Kellar was a breath of air. We discussed the results of the in office testing and set up a home sleep study to complete the exam. The most impressive evaluation of my exam came when he happened to pass by me in the hall during a walking/O2 test. When we met later on he noted that my O2 levels were acceptable but he noticed that I was extremely weak. As a result I am exerting significantly more effort to do simple functions like walking resulting in significantly heavier breathing. Going beyond the actual exam results he suggested physical exercises targeting areas that would help improve my breathing. The ensuing conversation was extremely useful and has given me more direction to improve my breathing.

Great job, lot good information. Thanks

My appt was on time, Amanda is very knowledgeable of sleep apnea. She takes her time and listens to your concerns. I only gave 4 stars because it is difficult to make an appt. I was always playing phone tag. I always had to leave a message for a call back. Never had a live person answer the phones.

Very amiable and helpful staff. Amanda gave us a thorough review and explanations of conditions . Also, she gave suggestions and helpful information regarding lifestyle changes, pertaining to our shortness of breath and fatigue problems.

Excellent care; reliable; friendly staff

Well you were awesome

Ms Law has been extremely helpful. She took the time to listen, to consider what i had to say and gave her professional feedback. Which I very much appreciated!

Good

Amanda Law has always been forthright, caring and easy to talk with. I have dealt with both Amanda and Dr. Kellar several years ago when my husband was seeing them. I was so very happy to see that she was still with the practice and believe her to be the best!

Appointments are on time.

Amanda helpful and knows her stuff. I would recommend her to any of my friends.

great response on phone with dr.kellar---timely advice and script done

Very friendly staff

Great customer service, was seeing another doctor in Elgin I had really bad experience with. After checking Dr. Kellar reviews decided to come see them. 100% recommended

Like allays, Dr. KELLAR, and his stuff provide the most possible professional and fast help. Congratulations!. I 'am his patient from 1998 and I am vary happy with that.

Everything was explained very good about my visit

Dr. Kellar was very personable.

Very nice talk with Dr. Kellar

Excellent staff and doctor. Everything was explained to me in an easy to understand way. All very courteous and helpful.

Amanda was very helpful in reviewing my status and setting up a new machine. I felt like she took all the time I needed for this visit.

The appointment with Amanda was thorough and what it should be. However she told me that someone from the office would call me to set up next year's appointment the same day we talked. No one called me at all.

Sharp, knowledgeable & professional. First face-to-face with Amanda but she knew everything in my medical file. Addressed both a recent Covid related matter, as well as my long Covid & upcoming scheduled tests. Wife & I both were impressed.

Very helpful even on short notice. Listens to concerns and good advice.

Very happy with my numerous experiences

Very thorough and easy to talk to

Friendly and knowledgeable staff. Excellent care.

It was superb.the tests were good and the interpretation of the results was even better. Can’t ask for much more. Thanks Jen Cantù and Dr. Denis Keller.

First visit….Everyone was very friendly & professional. Suggested change in Rx already has improved my condition.

Easy to set up appointment and check in. Completed testing inside of 20 minutes and saw the Doctor ten minutes later. I spent 10-15 minutes discussing results, treatment options and prescriptions. I'm very happy with the care received and would recommend this office to anyone interested in sleep study or pulminology appointment.

High level of care and concern.

The visit went fine no

It was such a pleasant experience this time with everyone we came in contact with today. It was like a new era. It makes all the difference in the world when people around you are nice to talk to and are willing to help you all the way. WAY TO GO NE Pulmonary & Sleep Medicine. Thanks

The whole experience from setting an appointment, check in, seeing the nurse, and doctor are welcoming & easy to work with. Thank you!

Great people

Excellent!!

Explained everything, answered every question.

Dr. Kellar is one of the best. He is very patient and takes his time with you. He is also one of the only doctors I have had that goes into great detail about your condition and other issues it could be stemming from. No other doctors I've had take that kind of time with you. My husband and I both see him and are very happy.

Learned more in 15 minutes with Dr Kellar than my previous doctor in 5 years. Very personable and thorough.

Everyone in the office is friendly and professional.

Dr. Spent time with me and over test results. Very friendly and thorough visit.

Great so far. No nonsense. Friendly staff. Dr K is straight to the point.

Everything was great!

The best there is

a positive experience. Amanda was very helpful and provided info to guide me.

Ms. Amanda Law takes time with patients and carefully explains test results and online CPap data. She is highly professional and delivers her recommendations and findings in a very comfortable way.

Dr Kellar is very nice but he also tells it to you like it is. He told me my breathing problems will only get worse if I don't start some strength training. I've reached the magic age of 70 when you have to keep moving it or you will lose it, without building muscle you can't last in a very productive way.

Able to work me in to the schedule and explained options and answered my questions. The staff was VERY friendly and helpful on the phone setting the appointment and in the office. Actually a person answered the phone and not a computer which today doesn't seem to happen. Good experience!

Nice group

Dr. Kellar & his staff are all very good at what they do, primarily helping us breathe. And, they do it professionally with compassion & humor. I have, over many decades, been seen by various Pulmonologists, but Dr. K & his whole group are amongst the best in the areas that count, giving a care about the patient.

All employees here are very responsible & respectable. Highly recommend

it was my first visit, recommended by my radiation oncologist. the testing was very thorough, and dr. kellar actually spoke english to me instead of doctor speak. i was truly amazed and told him so. i left there with a complete understanding of what was going on in my lung, and why. dr. kellar is without a doubt one of the top doctors on my lifetime list of doctors i've seen. if you go see him, tell him stuart sent you. i won't get a discount (insurance pays) but i'd like him to know that i'm referring people to him.

Very good Dr is responsive.

Dr. Keller was friendly and fast, but he covered everything he needed to.

Jenn takes good care of me, she ran the needed tests, checked my bipap machine and gave me advice and offered to call Apria to get a better mask for me. Dr. Keller was very informative and took time to talk to me about my condition and what can be helpful. Yes I will tell friends about this practice.

I had a good discussion with Amanda but am confused that I was told that I had to meet with Northwest Pulmonary staff in order to process an order for a replacement hose for my CPAP machine but the hose showed up next day so I'm confused why I had to meet with staff because the order was obviously place prior to my appointment with Amanda.

Dr. Kellar is a doctor that listens to you and takes time to explains everything to you. He answers your questions and doesn't rush you. He is pleasant too.
