Katie Greniger, CNP

Dermatology trained Certified Nurse Practitioner
Brief info

I obtained both my Bachelors and Masters of Science in Nursing through the University of North Dakota and have worked in healthcare for nearly 20 years. I'm passionate about providing exceptional care to the members of the community that I grew up in. Born in Brainerd and raised in Grand Rapids, I married my high school sweetheart and we have three beautiful daughters together. We all enjoy the great outdoors that Northern Minnesota provides, including water sports, fishing, hunting, biking, and walking miles of trails at Tioga. I have a passion for fitness and love spending time with family and friends.

Katie currently sees patients in Grand Rapids and Bigfork.

Dermatology professionals are DEFINITELY professional-Nicole Manecke is the BEST!! My husband and I both see her and think that she is truly on her game! She listens, she does thorough exams and we are relaxed and confident that we have received the best care one could want. Nurse Angela is a DELIGHT! She also was very professional and kind-easy to talk to—the two make a Superior team.

Friendly caring staff with nice clean and organized facilities. The online check in software was slow and clunky the day I used it and I got a second notice to check in after I already had done it.
