Nice to Meet You

Hey there! I’m Gretchen, your ADVENT Nurse Practitioner. It’s great to meet you! Let me share a little about myself. Before joining ADVENT, I worked in Dietetics and then spent time in the NICU. Now, I’m here to help the adult world breathe and sleep better. Being part of every step of your journey is incredibly fulfilling for me.

As my patient, you’re absolutely unique and special – no doubt about it! I want you to feel truly understood, and I’ll make sure you are actively involved in your care. Together, we’ll come up with a plan that’s tailored to your specific needs and gives you the best shot at achieving your goals.

I’m really excited to get to know you and be there for you throughout your patient journey at ADVENT.

How I Can Help

"I went to ENT's for years and they did very little to help my sinus issues. They just prescribed nasal sprays for years, one after another. Advent was great. All appointments were very detailed and informative. They spend a lot of time looking into my sinus problems. My breathing is so much better but not perfect after my procedure. I will take the improvement they gave me any day over the ENT doctors I saw before."

This place has literally changed my life. I have been a lifelong sufferer of sinus problems. Through the years, I have tried multiple over the counter remedies, seen several ENT specialists, and had a majorly invasive sinus surgery. None of it has ever really helped, and the surgery made it worse. I went to ADVENT...and I'm breathing more clearly than I ever thought possible. They truly delivered significant results. I am and will forever be grateful for the major improvement in the quality of my life.

This is a 1-stop-shop for issues dealing with those miserable nose, sinus and throat and breathing issues with lots of solutions and info to make an informed choice. Don’t waste your money on "a" specialist when it's all here under one roof and very reasonable cost wise. All we know is to go to Sleep centers that will slap miserable CPAP machines on you which only help with sleep disorders. Allergists give you sprays. Helpful....but ADVENT addresses several areas of sinus-nose-throat concerns. My Family member was given a Balloon Sinoplasty because sinuses were in bad shape from all previous nonsense and chronic drowning in mucus. He back at work next day with mild discomfort for 2 days. Major improvements! Was told if this didnt help as much as hoped, other things could be assessed. Very nice staff. Terrific follow up aftercare and support all along the way. very professional.
