ADVENT is celebrating 20 years of transforming lives with simple Airway- Breathing Solutions. On November 1, 2004, Dr. Madan Kandula and Dr. Gwen Kandula took a leap of faith by opening a small independent ENT practice, Advanced Ear Nose & Throat Specialists, in Milwaukee, Wisconsin. No patients. No network backing them. Just a determination to put patients first and deliver care without the bureaucracy and frustration found in large healthcare systems.
What began as a single office with three employees is now a trusted name in upper airway care, with 30 clinics across six states. 20 years later, ADVENT has treated over 111,000 patients and remains committed to the same mission: access to healthy Breathing Triangles.
Pioneering New Ways to Breathe Well
From the beginning, the Kandulas knew they wanted to practice healthcare differently. They focused on simple, in-office solutions that gave patients relief without the hassle often found in typical healthcare systems. In 2006, just two years after opening, ADVENT became the first clinic in Wisconsin to perform Balloon Sinuplasty—a breakthrough procedure that clears blocked sinuses quickly and effectively.
The momentum continued. In 2007, ADVENT introduced an in-office CT scanner, offering patients more convenient care with faster, more accurate diagnoses. Instead of waiting for follow-up appointments, patients could now speak with an ENT immediately after their scan to receive a diagnosis on the spot. These innovations embodied ADVENT’s patient-first approach: keep it simple, keep it effective.
The trust patients placed in ADVENT fueled our growth, laying the foundation for the expansion that followed. By our 10th anniversary, we had celebrated new clinics in Mequon, Wauwatosa, and Oconomowoc.
A Turning Point: The 2018 Rebrand
In 2018, we took our next big step—rebranding with a new name, ADVENT, a new logo, and a sharp focus on airway-breathing health. The new name reflected the heart of what our practice had become: a place where patients stuck in cycles of sinus issues, snoring, and poor sleep could find real solutions. And the new logo was intended to represent bold, edgy moves within the healthcare space.
As part of this transformation, ADVENT developed The Breathing Triangle®, a framework to help patients understand the connection between their nose and throat. When one part of the triangle is blocked, the entire airway system can fail, causing exhaustion, snoring, and chronic health problems. This model became the foundation of ADVENT’s care, allowing patients to finally connect their symptoms to the real cause—and find solutions that work.
The rebrand wasn’t just about a new name—it was about clarifying our mission. This sharper focus on breathing and sleep health set the stage for continued growth. By our 15th anniversary, we had opened our doors in Oak Creek & Pleasant Prairie, Wisconsin and Vernon Hills, Illinois, bringing our simple, in-office solutions beyond Wisconsin’s borders.
Responding to Patient Needs
ADVENT’s growth has always been driven by patient feedback and trust. As more patients came to us for help with sleep apnea, they made their frustrations with CPAP machines clear—bulky, uncomfortable, and difficult to manage. We responded by introducing Oral Appliance Therapy to our practice in 2022, giving patients a simpler, more comfortable way to reclaim their sleep.
This approach exemplifies ADVENT’s patient-first philosophy—listen, innovate, and deliver solutions that fit real lives. Today, patients from across the country and beyond travel to ADVENT for simple, in-office treatments that restore healthy breathing and restful sleep.
A Global Sinus & Sleep Destination
What started as one clinic in Milwaukee has grown into 30 locations across six states—Wisconsin, Illinois, Indiana, Minnesota, Ohio, and Tennessee. Patients visit ADVENT from around the world, drawn by the promise of effective, straightforward care. In response to growing demand, ADVENT has opened 24 new clinics in the last five years, continuing to expand access to innovative, in-office solutions:
- 2020: WI: Appleton; IL: Northbrook, Oak Park, Chicago Loop
- 2022: IN: South Bend, Goshen; MN: Blaine; WI: Green Bay
- 2023: MN: Eagan, Maple Grove, Woodbury
- 2024: IN: Avon, Keystone Crossing Indianapolis, Southport; TN: Franklin; OH: Miamisburg, Dublin
From the first 25 patients we saw in 2004 to the 20,000 patients treated this year, every milestone reflects our unwavering commitment to practicing healthcare differently. Innovations like our in-office Balloon Sinuplasty, Oral Appliance Therapy, Nasal Cryotherapy, and Allergy Drop Immunotherapy continue to set us apart, transforming lives one breath at a time.
