Do not recommend this place at all. After hearing a radio ad, I figured I'd set up an appointment and see what the doctor says about my breathing problems through my nose. I'm not usually even very critical but the front desk people were not all that professional at check in but whatever. Then, the real frustrations started though. I drove over an hour to this appointment and lo and behold... it's not a doctor. It's a physician's assistant that sees me. She didn't convey much knowledge or insight but just said let's do a nose scope and see if I can see anything. I explained I already had that done before but she could do it if she wanted. Thought this was part of the initial evaluation but no... IT'S A $600 SCOPE. Took her less than a minute to perform and there was absolutely no explanation this would cost any extra or be outside of the initial exam co-pay (I had already paid $40 for the appointment). So you're saying I have to pay $190 for a visit to not even be seen by a doctor and get no answers whatsoever? Unbelievable. After calling and talking to their billing department, they were not helpful either except for apologizing this was not explained and that it would be raised to their operations department. This place is a scam and provided no answers at all. Will be cancelling my "follow up" appointment and never going back. read more

Vernon Hills: I had a few surgeries and it has helped me sleep better, however insurance didn't cover one. So 8K out of pocket later i was set. All payments up front, paid in full. it covered follow up appointments too. Then the scammers say I owe another $1500 dollars!!! I just got a letter from a collection agency. Stay away from the liars!!! Trent Schlesinger read more

Went to breathe better. They statuses my turbinates were too large and reduced them in size. After the 1st follow up I developed a strep infection. I had not been in contact with anyone but them. After the strep infection I developed an ear infection. Informed them of such and they just asked am I taking antibiotics repeatedly. Informed them after 12 week follow up that I still wasn't breathing like I should and something felt blocked. I was told that they needed to perform another Head CT to find out what was blocking. I went to an ENT doctor with Aurora and they stated that there was nothing wrong with my breathing and allergies were to blame and that Advent suckers ppl into those things all the time. My insurance company paid about 30k for all their services over 12 weeks. I wouldn't recommend them. read more

It's been a week since I had my balloon synoplasty procedure and I'm worried that I'll never be right again . Following the procedure, I spiked a low grade fever and had flue like symptoms for four days . I still struggle with no energy , sinus headaches and not being able to get any decent sleep at night . The worse part is I blame myself for falling from the slick marketing and the promise of a quick recovery with appreciable results . All I know is I won't live like this , ill take matters into my own hands if I have to . read more

The billing issues are outrageous. I had the balloon thing done last week in Blaine, MN and was in the chair maybe 20 minutes and the total bill was over $13,000. Had a deviated septum "fixed" in April 2023 and the "doctor" who did the procedure 3 months earlier told me that my septum is still deviated when he was doing the balloon procedure. What the? This business is a total scam. If anyone is interested in a class action lawsuit, please email me at ottomik19@gmail.com. read more

I am a new patient who took the home sleep test, however after 5-6 days no one contacted me with the results. Tried to call my local Advent office, but could only reach a call center in WI. Actually I couldn't reach them because I received a recorded message to leave my phone number and I would get a call back within 24 hours. This system is terrible, why cant I just call my local office directly without going to a Wisconsin call center. Talk about impersonal service! read more

WOW pretyyyy boy Madan make beutiyful son I love his his body and It makes me so happy LOVE$ LOVE LOVE LOVE LOVE? read more

I went under the knife two times with Advent. First time was 2 procedures. Tubinate reduction and fixing a deviated septum. A few years later I went back because I still wasn't breathing well. Again had turbinates reduced and fixed my deviated septum (because apparently they didn't get it right the first time). They also did balloon synoplasty on my second surgery. Today (about 6 years later), and I still can't breathe. It's really no different than before all the procedures. I went in a couple years ago to ask them why nothing has worked and that visit was another cha-ching for them. Healthcare is the only industry where they can get it wrong and when you ask about it, they charge you again. Anyhow, I may have another procedure at some point because not breathing through the nose is no way to live, but it wont be with Advent. I wish they helped my situation, but they didn't. And the cost, inconvenience and discomfort (for a couple weeks after each surgery) makes all of it very unfortunate. read more

A big shout out to Alyssa B. in the Advent billing department!! The MOST friendly, courteous, patient, knowledgeable, and helpful woman I have ever dealt with when dealing with billing departments in a medical setting. She went out of her way to work with me. You just don't find that kind of customer service any longer. I thank you, Alyssa! read more

I think this place is simply a scam! Their big thing is just to get you to do the x-ray of your head, which is around $600.00 out of pocket. Insurance won't pay much. Don't start down this road. If you sink the $600.00 in their scam programs, you may want to continue "chasing the dragon" so to speak AND, Having sunk the upfront money, you continue to throw more money at these "phoneys" . Notice the lack of people in the parking - folks are generally smarter than me- I don't know how they stay in business? Anyway , after you let these snake oil salesmen con you, and you plunk the $600.00 money down supposedly they will shrink you Nasal Turbinates" or some thing like that? Ads play on the radio constantly saying how they will cure you . all lies Personally, I paid for the 600.00 xray, in feb 2020, and missed my MUST return date by 1 month because of Covid. They said I had to pay another 600.00 and/OR, succumb to another x-ray and the $600.00 fee again. I said no way. Wrote them I nice letter asking them for a refund of original, 600.00, they just blew me off! read more

My husband was the first among us to visit Advent and had a sinus procedure so he could breathe more easily. His snoring was atrocious and sometimes he would shake the bed. He had a procedure with Dr. Kandula and was breathing better that day. His snoring disappeared. I was so impressed, that I had to try Advent myself. I went into this with the attitude that I had had a conventional sinus surgery 8 years earlier and they would tell me there was nothing they could do. However, a scan (which they do right there and it literally takes 2 minutes and is painless - you are sitting. revealed that they could help clean out the sinus area so I could breathe better and get less sinus infections which is the reason I had the first surgery. I have been plagued with sinus infections in the lovely Wisconsin winters all my life. I had the same procedure with Dr. Ethan Handler and it was amazing how much better my breathing became and how fewer sinus infections I now get. I am very thankful to Advent (as is my husband) for improving our quality of life. read more

I previously wrote another review but Yelp keeps on removing bad reviews and leaves the good ones. Advent knows charges three times the cost of any other ear nose and throat doctor so please do your homework before you use these guys read more

This is a fake business. They get you in and have an unqualified technician see you and diagnose you. They wanted to put me on over the counter allergy medicine for the rest of my life. That is the advent solution. What a joke. They make it sound very different in their advertising. False advertising. They bill your insurance and even though I told them to only do what my insurance covers, and even though they did absolutely nothing for me, whiteout getting a bill, they suddenly send a collection agency after me. I'm disgusted. One star is way too much for them. read more

TURN 180 DEGREES AND RUN! I only wished I had researched Yelp! before hiring Advent for my son's breathing issues. This outfit is a poster child for what is wrong with the American medical system. My son had a deviated septum procedure and we were charged 3-4 times what is normal and customary. Advice: never go to a surgeon who is connected to an independent surgery center, because you know they are in cahoots with each other. I naively thought that my insurance company would serve as a buffer, however they paid the ridiculous bill and left me with a hefty co-pay. To make matters worse, I would rate my son's outcome as substandard. PLEASE! Don't fall for those warm and fuzzy advertisements. If you do, remember to get all costs upfront and match those to customary charges for the exact same procedure. My worst medical experience. Ever. read more

The paperwork before the appointment with the extensive language about paying if your insurance does not was a tip off. Had to sign a special form about exploring your nose with a scope. Then was seen by a guy who has been only doing this for one year. Bill came and sure enough for a 30 minute visit of talking and a 3 minute scope review of your nose - $1000 bill. $700 for the 3 minute scope. After insurance rightfully knocking down these obscene elevated costs, I am 'lucky' to only be paying $300 for a BS visit. Will not be going back. These other reviews helped me avoid the next step with the CT scan and costs only going up. Previous visits to ENT doctors were able to look at my condition and have treatment w/o an expensive CT scan. Whole thing is a sham with extensive marketing on the radio. read more

Wished I would have read these reviews before getting involved with this place. Just received my first bill for my 20 minute evaluation and sleep test and after insurance it was $973. How can they charge $1100 for 2 sprays into my nose and a mint lifesaver candy and charge that amount? My advice is to avoid this company at all cost. After reading other reviews I feel lucky that I got out before the real costs were incurred. read more

On 2010 I had many issues with breathing and sleeping due to nasal congestion. I went to see ADVENT to see if they could help. They determined that I needed a Septoplasti surgery to correct my deviated septum. Almost 9 years after the fact, I am still issue free and as a result have been able to sleep better. I received great great and great service. Hernan G (grateful customer) read more

I was able to get my son in quickly for an appointment to address our concerns. They listened, the testing was quick and we got instant results and recommendations. No procedure needed. My mom then made an appointment, had an in office procedure and tells me often how she can now take a deep breath through her nose and can finally breathe. She had a cpap machine for years (from another doctor) that she was able to ditch due to being misdiagnosed from her primary doctor from years ago. So glad she was diagnosed correctly and can breathe properly. All costs went through our insurance plan, so we paid what our insurance plan outlines for co-pays and deductibles. read more

Awfully Zero help but certainly quick to want all their fees They advertise they can help with chronic issues but push it off onto other clinics Do not go here read more

Changed my life! Years ago an ENT doctor stuck a tube with a light at the end of it up my nose and down my throat ($800 "procedure") and told me I had unusually small nasal passages and esophagus for an adult. Told me to use a nasal spray. Later a cpap machine and years of restless horrible sleep! My doctor recommended Advent. Changed my life the same day! I cannot tell you how wonderful it is to be able to breathe comfortably through my nose! My snoring was reduced (except when on my back). I do sleep with an oral appliance provided by Advent because I do have an excess amount of soft tissue in the back of my throat. After YEARS of thinking I couldn't breathe through my nose because of allergies, constantly congested I am happily able to take deep breathes through my nose. NO MORE machines! My husband is thrilled, he can sleep now too! read more

It felt like a used car sales pitch rather than a legitimate medical appointment. You are required to see a physicians assistant prior to being allowed to book an appointment with the actual doctor. Never trust any medical practice that advertises on radio/billboards!!!! Also beware they require you to have a nasal endoscopy (camera inserted into your nose/throat) during the initial appointment which is classified as "surgery" by most insurance providers as a "body cavity was entered" and may likely bill at exorbitant rates (my personal out-of-pocket cost was $980 just for the initial exam). read more

SCAM ALERT and STAY AWAY. They will bill you for everything. Almost seems to be illegal. AND DON'T do the Balloon sinuplasty. S60,000 and some change later, I am still not breathing. Then they tell you to get a CPAP machine. They should have offered the CPAP first in the first place but they are trying to scam the shit out of you. STAY AWAY and you have been warned! read more

Three years ago I had their balloon procedure after it was recommended after the consultation. They had me thinking that eventually they were going to do a procedure to correct my snoring/apnea problem. It didn't happen. Instead, I got stuck with a cpap machine and a $2200.00 bill. I'm worse off now than before I went in. I can still count on stuffy nose and sinus infections every winter. These guys are a huge ripoff. I think they call it bait and switch. read more

I had a nose medical procedure with Advent ENT in Oconomowoc a week ago. Today at 5:15 pm was my 1st follow up appointment for how I am healing. At 5:07 PM Advent called me to let me know they had a lock down yesterday and their front door keeps locking. I should call them to be let in if I find it locked. I let her know I was a little late as I got delayed behind a car accident. She informed me if I was more than 5 minutes late, my appointment would have to be rescheduled. At 5:18 PM I parked in the parking lot. I went to the front door of the building and found it locked. At 5:19 PM I called their office number. Their VRU took about 45 seconds to get me in queue for a person. Just then, someone came out and let me in. I entered their actual office door about 15 SECONDS past my 5 minute deadline. They refused to see me! 15 seconds and the locked building door issue too! I called their customer service department and was advised the policy is 10 minutes late, not 5 minutes late. I made arrangements to do my follow up care at the Oak Creek ENT office where I hope the customer service will be better. The level of customer care at the Oconomowoc WI ENT office would be a zero if this system let me enter it. I should have believed the reviews I read about this place. They were over the top nice before my procedure. Now they already have my money and obviously, don't care. read more

Dont get me wrong. The people at vernon hills location are all stars. Very friendly and courteous. I received my bill and nearly choked. Even though I have very good insurance, I still have a lot out of pocket. Amount charged to insurance will be $50,000+ all said and done. Allergy test, CT scan, sit in the chair for 45 minutes. When I average the time I spent there it comes out to about $20,000 an hour. Seems excessive. Oh yea, the sleep study. Way way way over priced. No wonder insurance is so expensive. read more

Husband has had several procedures done. First one was in the hospital, others in house. Our insurance covered, but our balance has been in the thousands. He still had issues. I tried my best for him to see someone else for second opinion, but he kept going back to the people who couldn't give him relief! Last two procedures were this past fall and again this winter. First charge over $7,000. Didn't fix his issue. They convince him to have yet another procedure! Just got the bill- $41,000!!!. In house procedure, not a hospital. And an additional $5,000 for the PA to be attending?! Our insurance covered most but still have to come up with thousands on our own. 4 mos later he still snores and constantly sniffling, uses a nasal rinse daily. Would be worth it if he's cured, but that's looking unlikely. I'm frustrated he had this done without knowing costs beforehand. He did have to hold off a bit while they had to convince insurance to cover it. Feel scammed. read more

I had septum deviation procedure, nothing changed today except me paying out of pocket 3000 and my insurance paying hell lot of money. Later they advised to under go food allergy test ? Dont know why he didn't get that idea before the procedure...weird... read more

This place is a scam. We were just told that they won't accept a recent CT scan done at a different facility that is in-network because they obviously want to charge us out of pocket to do theirs- total BS! Proceed with caution! read more

I came in with breathing problems. They went and burned somethings out of my nose. I had it done 15 day's ago. Was the worst thing I ever had done. Now I can not use CPAC machine because I can not breath out of nose at all. I just keep getting run around about my nose. They did more damage. Terrible Place would never recommend. read more

6 Months later they send bills.. Bills of which I had no knowledge of ever suppose to get. Two office visits, and one Zoom visit and BOOM well over 1K just in office visits. Lets talk the CT scan that required, another 1K. What a waste. Know your upfront cost before proceeding. Understated what they will not tell you. I did not go with the operation, because after all that, they said the operation would cost up near 5K. Guess they will receive $10.00 a month from me. read more

Run Away. Money Grubbers. I was on a payment plan for 2 years, never missed a payment until severe medical issues in my immediate family kept me from my finances for a few weeks. I asked for help and missed a payment while finances were tight. I was threatened with collection agencies and told to pay in full. They hid behind their insurance contracts as a healthcare provider, stating they were required to collect all co-payments not covered by insurance. Heartless I couldn't even believe my insurance paid the outrageous fees for services. Be sure to preapprove services and make sure you are not financially responsible for charges considered to be over and above the medical standards. New 2019 laws require posted fees and prices for health services, shop and compare, BUYER BEWARE. read more

I wouldn't classify as a total scam; but, the charges are shameful and their accounting/billing system is horrible. My wife has experienced better breathing since procedures but at ~$18,000 per nostril/side for less than 30 minutes in office I'd recommend extreme caution to potential customers. read more

I was excited by the radio commercials that seemed like they finally would solve my snoring and apnea issues. I was seen not by a doctor but by an assistant, who was very nice, and for her 25 minutes with me I was billed $800. She prescribed nasal spray and said that one of the snoring contraptions advertised on radio might be a good fit for me. I went in really excited to find my issue and instead left just as frustrated. They wanted to set up another appt but I just can not afford it. The very opulent facility let me know that the appointment would be crazy expensive. Back to the drawing board I guess. read more

SCAM alert! Do NOT go to this place. They treat you like a number and get you back as often as they can and charge outrageous price for nothing. I went for a snoring problem. I've been to other real specialists, have tried numerous products, had 3 sleep studies which all were negative for sleep apnea. I go to Appleton location as a last resort to see what they have to say. After numerous visits, an at-home sleep study that showed sleep apnea, CT scan, blah, blah, they suggested 3 procedures even without seeing a doctor. The insurance only covered one, they said the other 2 were not necessary. That should've been a clue. Had the turbinate reduction and it did not go well. I was worse off, had to keep going back for follow ups and another procedure to cut out scar tissue?! And of course each visit was over $1800 and never saw the doctor again. Four months later and no improvement. Snoring is still awful. I don't feel any change in nasal airflow, but I am NOT going back for more "procedures". I'm getting a second opinion from a professional and we'll go from there. Would NEVER recommend this scam business. Each office visit was rushed, very impersonal, just not a good feeling. read more

Wife recently went in as she was snoring badly at night. After an array of tests, sleep studies and a bunch of other non sense, they say she is fine and I have a $2,200 bill. This place is a complete scam and insurance does not cover. They will not discuss costs at all.... and will tell you insurance covers when it does not. Stay away!!!! read more

I can see why this place has a 2 star rating. Keep calling my phone asking for a Jamie with a 259 area code...my name is not Jamie nor is there one at my number. And, I have a 414 area code. Saying goes, "good help is hard to find." read more

Don't go here! I had sinus surgery, a corrected deviated septum and reduced turbinates in May 2018 and my nose is still stuffy. When I called to schedule an appointment to see why my nose is stuffy, I was sent to the billing department and told that because of my balance (which we had been making monthly payments to) they would not see me until the balance was paid in full. They send the balance to a collection agency even though we had been making monthly payments. read more

I snored sometimes so loud the cats ran away. I lived on Afrin...couldn't sleep without it. This went on for years. Maybe 10 years at least. Went to nose and throat specialists before and still went back on Afrin. I didn't sleep well.Went to 2 overnight sleep studies and a couple home studies. I was losing energy. I finally made an appointment with Advent and after my preliminary visit I stopped Afrin. I did the rinse and Flonase. They did a scan of my sinuses and recommended the surgery. I had it done. I can breathe a lot better, sleep a lot better, have more energy. The doctor and staff were fantastic and answered all my questions even before I asked them. The rinse cleaned out allergens too. I would even do a testimonial. Give it a try. Yes you feel like you have a mild cold for a couple days after but without a suffy nose. It's worth it. read more

Advent charges an outrageous amount and they are not straight forward about it. They didn't help my nose either, the "doctor", who was a finance major, gave me a prescription for meds that did nothing. Insurance didn't cover anything either. Don't go here, go to your regular in-network doctor. This place is a complete scam and I will not be visiting them again. read more

I suffered for many years with chronic sinus infections. I was always on antibiotics and the worst drug ever prednisone constantly. I took ibuprofen daily because of the sinus pressure in my head. I had troubles sleeping because the sinus pressure hurt to lay flat. People used to say I sounded stuffy all the time. I was allergy tested by Advent and I found out a lot about what was constantly making me sick. I also had a CT scan done and saw the blockage that I had. I now am doing allergy injections and did Balloon Sinuplasty back in December 2020. Best two things I ever did. It is almost a full year since this all happened and not one time have I been to a doctor with a sinus infection. I have not had to be on antibiotics or prednisone since my surgery. I sleep better laying flat, I don't take ibuprofen like candy anymore and people tell me I don't sound stuffy anymore. While people told me what a bad allergy season it was in 2021, I didn't agree because I was great all year. Why I waited so long is beyond me. I am glad I let no-one talk me out of doing this. Thank you Advent!!! read more
