Chace Nacke, APRN
Chace brings a well-rounded clinical perspective to the urology team, drawing on his experience in inpatient rehabilitation to provide thoughtful, patient-centered care across a variety of settings. His background has given him a strong appreciation for the importance of looking at the whole patient, understanding their individual needs, and helping them feel comfortable and confident throughout their care.
In his role with the practice, Chace divides his time between the hospital and the clinic. He rounds on urology patients in the hospital, helping manage their care and working closely with the rest of the medical team. He also enjoys his time in the clinic, where he has the opportunity to get to know patients, answer questions, discuss treatment options, and help guide them through their urologic care. Whether he is seeing a patient in the hospital or across the exam room table, Chace strives to make each patient feel heard, informed, and cared for.
Outside of work, Chace is a proud Florida Gators fan and is always happy to talk college football - especially when the Gators are playing. He is also a dedicated coffee enthusiast and considers a good cup of coffee an essential part of getting through a busy day. And because hospital rounds and clinic schedules can make for long days, Chace believes in the importance of keeping plenty of snacks within reach to stay fueled and ready for whatever the day brings.
Chace is grateful for the opportunity to care for patients and be part of their healthcare journey. He looks forward to building lasting relationships with patients and helping them navigate their urologic care with compassion, communication, and a little bit of Gator spirit along the way.

Testimonials
Dr. Marella is a Saint as far as I am concerned. Even though he was not my personal doctor, he came out on a holiday weekend to perform an emergency surgical procedure. He was knowledgeable, professional, and took care of my urgent needs in a timely manner. I can't thank him enough.

My husband saw Dr. Marrello in the Tavares office for the first time last week. He had had surgery on 2/11/2022. He was referred to an urologist as unable to urinate following surgery. Since his urologist could not see him for a month, we decided to try Dr. Marrella. His office got him in right away. They removed the catheter and gave him thorough instructions. Very clean office and a welcoming staff. Dr. Marrella took all the time necessary with us. When my husband had a question after he had finished, he came back into the examine room to talk with us again. We highly recommend Dr. Marrella and his staff. We have a follow up visit this week.
