Megan was super friendly and professional with the testing. Dr. N exceeded my expectations. I was previously seeing Dr. Paul Stewart at Pulmonary Associates (absolutely terrible bedside manner, long wait times) so I am so happy with the switch! Ambiance: clean waiting room with local news playing on the flatscreen TV. Would be nice if they would put on the closed captioning. Location: on the third floor of the Comprehensive Cancer Center building. Plenty of parking in front of building.

Took 4 months to see Dr Walter Willoughby and confirmed with insurance they are in network…read more Everything went well during my only visit, onsite tests done and extensive useful info from an old but caring and professional Dr. The problem came when I was billed $1,229 dollars for the single Dec 2, 2025 visit. Turns out my insurance doesn't cover it because they are out of network. Well turns out Dr office billing used Jeff Willoughby instead of Walter, maybe the son from a different location. I tried to reach out to the billing person, Michelle, many times and have not received a callback or response. Initially the bill was for multiple visit charges and when speaking to Michelle about the discrepancy she just informed sh would remove all charges because in order to go to a 2nd appt for online confirmation all bills need to be paid. Then she said if insurance doesn't pay they will usually write off the extra charges. Well what good is it to see an amazing Dr if you have to deal with billing issues from hell from their office?? I am unable to see Dr because I don't want my bills to double on every visit. **Update** Michelle from billing researched the issue and turns out that although Dr. Walter Jeff Willoughby is covered under insurance BCBS, my coverage is under a subset called HPN (High Performance Network) , which the Dr. is not covered under and thus the billing issue. Sadly I'm not covered as the office is out of network. Dr. Willoughby is very thorough, caring, and professional, he helped me find a better medication and he will be missed. Thankfully, Michelle in billing has empathy and sincerely apologized for the issue and stress it caused me and wiped the billing clean to zero balance God bless her!

I was referred to Dr. Willoughby by my primary after a CT scan showed an area of concern. When I…read morearrived, I was given several breathing tests and they did a blood gas test. After the tests, you are moved to a room where you sit and wait to see the doctor. I assume that he is going over your test results so when you're taken to his office, he knows your history and is ready to discuss the results and any issues you might have. During my first appointment, Dr. Willoughby recommended I get a PET scan to further check that area of concern. After the scan, I returned for a second appointment. The same breathing tests were done as well as a walk test lasting 6 minutes. Again, I was shown to the exam room to wait for the doctor. He had already made a copy of the Desert Radiology report of the scan to give to me. He showed me the scan on his computer and we discussed the results. Dr. Willoughby told me he was referring to me to another pulmonologist for a second opinion (those are my words). In any case, I have an appointment to follow up with another doctor to decide where to go from here. I found Dr. Willoughby to be ready to answer any question I had. He didn't hurry me and he explained things very well! It also was the first time a physician showed me an actual scan instead of just reading the findings on paper. I had confidence that I was in able hands. And, on a scale of 1 to 10, he dropped my anxiety level from 12 to 3.

First of all, DO NOT GO HERE! For context, I lived on the…read moreEast Coast for 35 years and NEVER experienced the level of unprofessionalism at doctors offices that I've experienced since I moved back here to Las Vegas. My experience was pretty much the same as other reviewers. Specifically, rude and unhelpful office staff. Also, the doctor was okay but not worth putting up with the despicable treatment from the front office staff to waste my time coming back to see. I had been to the office once and had gotten there early. At my second appointment, I arrived seven minutes late. I had been caught up in traffic with heavy roadwork. I was not intentionally late and had given myself the normal amount of extra time to get there. It was not my fault but I was treated like it was. When the girl at the desk informed me of the late arrival policy and she turned me away, I was shocked, as she pointed to a notice which was taped on the glass separating me from her. It said something to the effect of... late arrivals will not be seen. I informed her that I had not seen that notice when I was at my last appointment and that there was nothing on the website specifying any such policy. She just looked at me with a blank stare. I left there FUMING, swearing to never go back. Then a month or so later, to my utter amazement, I received a bill for the appointment I was turned away from. I then called my insurance company and reported these people and was assured that they were not about to pay for an appointment that I showed up for and was then denied. So, remember to always inform your insurance company if a doctors office tries to pull a fast one on you like these guys did to me. This is the worst business I've ever dealt with. These people obviously don't know how to run a business and should not BE in business. I've got some serious issues going on between my heart and lungs and I can't afford to be jerked around. Fortunately, my kids live in L.A. so I've decided to see specialists in that area. It's a slight hassle but well worth it to get the level of care that I can't seem to find here which actually also includes COMMUNICATING with the doctors office. As I said before, DO NOT GO HERE.
