I am very happy that I found and met Dr. Morgan and his professional staff…read more He took his time and put great detail in finding out what caused my severe allergies. The allergy test was very interesting and he was very knowledgeable at the results and explained to me in detail what I was allergic to and not. Then he prescribed me some skin allergy medications that I never heard of .... But most importantly, they worked on my skin. His office team is also very efficient, friendly and knowledgeable. When I needed a prescription refill or appointment with another dermatologist, they sent the referral right away. I am ultra impressed with this.

Needed to do an update- Dr Khan may be a good Dr but his staff reflect on him as well. This is…read moreabout improper billing and prior authorizations.. Dr Khan is a great Dr. The problems are with his billing and getting prior authorizations. They will bill you and your insurance company for things you've never had in his office- like albuterol or tests you never had done. When you call his billing dept they always say the same thing, we don't know what each patient gets so we just bill everyone for it, bet our insurance companies want to hear that. They didn't get prior authorization for my last appt then billed insurance for multiple tests I never received. This appt they put in for the wrong thing. I don't have sleep apnea, never have, I'm an asthma patient, but my authorization for todays appt is for sleep apnea, which means the insurance company will deny yet another claim from his office.

What: breathing test with Megan and first appointment with pulmonary specialist Dr. Ralph…read moreNietrzeba. Service: really pleasant experience all around. 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.

Dr. Wojcik is very knowledgeable and professional, but once you leave him, you're on your own. It took months to get her prescribed medication. And now longer for her oxygenator.

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 have a 50% chance of getting an adult that pulls up my file and sincerely has a conversation and tries to help, and a 50% chance of getting what I can only presume is a teenage girl that says 5 words that don't make sense and then redirects my call.

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.

I rarely leave a negative review but I've been having some respiratory issues for some time now and…read moregetting a hold of anyone via the customer service line is difficult. Both times I've called have been a minimum of 45 minutes waiting with constant and incessant "your call is very important to us" messaging. The first follow-up call I received was from an unknown number/invalid caller ID. Not even a local Vegas number so I regretfully didn't answer it as it looked like spam. The doctor and staff were nice and helpful. This review is purely from the perspective of hold times, the hold music/messaging, and the endless transfers when you finally do reach someone.
