Staff Directory Bios – Circulation

Cathy Holnagel, Circulation Supervisor

I’m an “old timer” having worked in various areas of the Cedarburg Library for 30 years. The last 6 years have been as Circulation Supervisor. We have six wonderful library aides who keep the Circulation Department running, and two CHS students who shelve our returned books. I LOVE books and so this is the place for me!



Jeff Messerman, Library Associate

I’ve been here 3 years, starting as the person who unpacked the van delivery every morning and moving my way over to “Library Associate,” which basically means every new book that comes down the pike passes through my hands first. Yes, getting first look at the new books is absolutely as cool as it sounds! When I’m not tossing books around (gently, always gently) I’m in the Radio Room tending to all the sounds of our internet radio station, CPL Radio, which streams 24 hours a day. When I’m not at the library, you can find me at home with my wife and five kids, two dogs, one very dangerous-to-mice Siamese cat, and a guinea pig named Rollo who possibly might live forever…seriously, she’s really old.

Sharon Hartley Iverson, Library Aide

I’ve always been a lover of books and a life-long learner and I am excited to be a new member of the CPL learning community.  My background includes both education and visual art where I have taught for the past 25 years. In addition to teaching and artmaking, I love all things nature—from gardening to exploring the woods and prairies in our area to collecting stones and lake glass from Lake Michigan. A favorite pastime is to relax with a strong cup of coffee and a new piece of fiction by a favorite author—Barbara Kingsolver, Ian McEwan, Ann Patchett, Alexander McCall Smith, Elizabeth Strout, and the list goes on…It’s my privilege to join the staff at CPL and I’m looking forward to assisting patrons with their library needs.

Donna Roszak, Library Aide

As a retired high school Spanish teacher, I am excited to be a part of the Circulation Department where I have the opportunity to aid library patrons with all the wonderful services the Cedarburg Public Library has to offer. I am also a self-published author of a curriculum-aligned question and answer book, “Ask Me Smarter – Brain Questions for Kids to Help Them Soar to Scholastic Success.” It is aimed at parents, teachers, and home-schooling families of elementary school children grades PreK-5th grade. It is available on Amazon. I am a strong believer that knowledge is potential power. I also create Spanish teacher products at Teachers Pay Teachers with my store, “Ask Me Smarter / ¡Pregúntame!” I live in Cedarburg with my husband Paul, and two sons, Joey and Lucas. Our family loves to travel, fish, hike, and relax in the North Woods. We are also avid Brewer, Packer, Buck, and Badger fans. I am excited to learn and grow along with all library patrons as I continue on this journey. Our beautiful library has something for everyone, and all can be assured that it echoes the famous Dr. Seuss mantra, “Oh the Places You’ll Go.”

Megan Ferstenfeld-Torres, Library Aide

I’m excited to join the CPL staff as a part-time Library Aide after a long stint as a stay-at-home mom.  I have been residing in Cedarburg for the past 11 years with my husband and two sons, ages 12 and 8. My family and I enjoy spending time outdoors hiking and camping and taking in all that Cedarburg and Wisconsin have to offer.   Before moving to Cedarburg, I practiced law in San Francisco and Los Angeles.  I also hold a BA from the University of Notre Dame in Political Science and Spanish Language and Literature. As a research-oriented attorney and all-around avid reader, I have spent many hours in and out of libraries and am thrilled to be able to serve the Cedarburg community in a library setting.

Molly Witte, Library Aide

I have lived in Cedarburg for most of my life. After moving across the country for school and work, my husband and I returned to Cedarburg to raise our two daughters in this wonderful community. I have been privileged to work in the Circulation department of the Cedarburg library since 2015. I assist with book repair and also volunteer at my daughters’ school library. Besides reading, I love cooking and walking my dog around town.


Jill Wiza, Library Aide

After spending 17 years in the healthcare industry working as an RN in both hospital and public health settings, I was fortunate to be able to become a stay at home mom to my growing children. Fast forward to 2006 when my youngest started at Webster and I walked into CPL and noticed a job opening in Circulation. Hired by our former director, Mary Marquardt, I never looked back. I have always loved libraries and feel blessed to work with an amazing staff, and I particularly enjoy all of the special programs we offer. One of my favorites was the presentation on comfort animals.
