Founded in 2004 by Dr. Madan Kandula, board-certified otolaryngologist sinus and sleep surgeon, and Dr. Gwen Kandula, audiologist, ADVENT is an alternative to conventional ENT practices. Having realized no other industry would treat consumers the way they’re treated in healthcare, ADVENT resolved to redefine the patient experience, leaving behind the long wait times, uncertainty, and dismissal and moving toward innovation, memorable care and simple in-office solutions.

“Friends and family would say…what are you on right now? I would just say I’m on sleep, I’m awake, I’ve got all this energy. And it’s an amazing thing. And it’s every day.”
“Before my procedure, I had a lot of headaches on a regular basis – I was missing work, not able to participate in my kids lives or family social life and those have gone away. It’s been very life-changing as I got my life back and I am able to fully engage and enjoy the things we like to do as a family.”
