Your 2019-2020 Tri-Presidents


Chelsea Blum

I am very excited to be one of your ONN Tri-Presidents. This is my third year in ONN and my second year serving as a board member. I have loved my time in this club especially my years on the Board. I have made lasting friendships, read books I wouldn’t have gravitated to myself and ENJOYED them, broadened my horizons with trying new local businesses and have grown tremendously as a person. 


My family and I moved to Oconomowoc in the summer of 2017 when I was 8 months pregnant with my son Cayson. We moved here from Milwaukee where we spent the last 6 years. My Husband Brian and I have a beautiful daughter Brielle who is 3.5 going on 13 and a very adventurous 2 year old son Cayson.


Brian and I met on a 6 seater airplane. We were 2 of the 3 passengers on it. It’s a cute story, ask me about it at a Mingle and I’d love to share! We are going on our fifth year of marriage and we’re enjoying every minute of it. 


This year in ONN I hope to meet many more new friends and assist in the growth of our community. Let’s make this the best year yet! Cheers to 2019-2020! 

Laura Adams

Hello! I'm so excited and looking forward to being your tri- president! This is my second year being a part of ONN.


My husband and I are born and raised in Oconomowoc and high school sweet hearts. Just after college we bought our first home in Waukesha. We had our two boys, who are almost 6 and 4, while living there. Nearly 10 years later, we moved back to Oconomowoc and are so happy to be back! As a family, we love exploring the outdoors, playing sports in our backyard and staying active in our community! 


I'm looking forward to meeting you in person at the monthly mingles and other ONN events!

Katy Tessmer

I am very excited to be one of your Tr-Presidents this year. I have been a member of ONN for 2 years. I tried out a mingle once and thought this is a fun group of woman  would like to hang out with more. I continued to join the club and attend mingles. I am now excited to help put on those mingles for everyone as a board member. 


I moved to the Lake Country area 12 years ago from Michigan. My husband Jim and I met freshman year in college and have been married 11 years with 2 kids James 9, Emmalyn 6. I absolutely love everything about Oconomowoc and the Lake Country area. As a family we enjoy outdoor activities all year round including wake boarding, hiking, and  ice fishing. I am a local realtor with Keller Williams in Hartland and love helping families find their homes. 


Elise Miller

Hello, I am this year’s treasurer.  I am a newer member to ONN but have lived in Lake Country for almost a decade.  I currently reside in Hartland with my husband, Nick, our two young daughters, our vegan dog, one scaredy cat, and lots of fish.  Our family is self-employed and we own business in Downtown Hartland called Lake Country Bed Barn. I take care of the books for the business, so I feel I well equipped in financial knowledge to be the treasurer. I am looking forward to having a position on the board to be more involved in the club.


In my free time you can find us hanging out in Lake Country at a new restaurant or visiting local parks and lakes.  I also enjoy many DIY crafts, cooking, and gardening. I am always up for a get together with coffee or cocktails!



Danielle "Danyee" Hartmann

Hello there! This is my first year with ONN and being on the board. I am also new to the Lake Country area. I grew up in Menomonee Falls and have lived in Wisconsin most of my life. However, I decided to join ONN and be on the board because I wanted to meet new people and be part of a great organization of women who support each other, encourage one another, and also have fun together!

My boyfriend Adam and I were introduced back in 2015 by his sister & husband who are one of my brother’s best friends. It took about 3 ½ years of us being friends and telling him I was moving to Florida to make me realize I liked him. We were long distance for our first year of dating, then I moved back to Wisconsin and now we reside in Delafield. I’m a Graphic Designer for Bubon Orthodontics and also freelance on the side. Adam is a Production Manager for his family business at MIRO Manufacturing. In our spare time, we enjoy being on the lake and going boating, playing volleyball, working out, Sunday brunch, exploring breweries, shopping (maybe that’s just me :) ), spending time with friends and our family. I look forward to meeting all of you at our upcoming events and also being your Membership Coordinator for the 2019-2020 year!

Secretary / Website Coordinator

Janine Haar

Hi everyone! This year, I am your secretary and website coordinator.  This is my third year in ONN. I joined early in 2017 after moving to Oconomowoc from Pennsylvania. I have absolutely fallen in love with Lake Country! I work in compliance for an employee benefits company. 

My brother and his family also live in the area and I love spending time with my two nephews! I love to travel and see new things - whether close to home or further away. I am always up for an adventure!!  I enjoy skiing, hiking, kayaking, and getting into crafty projects. I also love doing home improvements. If you are ever looking to go somewhere or try something new and need a partner in crime, let me know!
