Renen R. Sahr

Before joining First State Financial Services, I attended Midland University earning a bachelor's degree in Business Administration with a focus on Accounting. I then went on to attain the Life, Accident, and Health Insurance Licenses, as well as FINRA series 7 and 66 registrations.

I most recently attained the Certified Financial Planner designation. To become a CFP®, an individual must demonstrate an in-depth knowledge of the diverse financial planning topics. These topics include investment planning, tax planning, retirement planning, estate planning, insurance planning, financial management, and education planning. The average student will study approximately 1000 hours in preparation to sit for the comprehensive exam.

I thoroughly enjoy creating individualized financial plans that help clients reach their financial goals and feel confident in their financial futures. 

As a former golfer at Midland University, I still enjoy getting out to the course when I can. I am originally from Gordon, NE where I grew up on a small acreage and I now reside in Fremont.

As a Wealth Management Advisor, I'm here to help you plan for what's to come, protect what matters most, and invest in your future. By getting to know you and the things that are most important to you, my team and I will customize a plan to fit your specific needs. I believe nothing can really replace the value of the face-to-face interaction I have with my clients. I currently hold FINRA series 7 and 66 licenses.

One of the benefits of working with me is my ability to provide clear, easily understood explanations of financial products and services. The personalized program that I can provide is a roadmap to a more comfortable financial future.

My wife, Lyndsy and I have been married for 17 years and have lived in the Blair/Valley communities for the last 20. We both attended Dana College. In our spare time we enjoy watching our two sons, Cade and Brock, compete.

I have been working with individuals and businesses in the financial services area for over 38 years. I hold licenses 7, 63, 66, and 24. I am also licensed to provide; life, accident & health, and long-term care insurance.

I am dedicated to developing lifelong relationships with all of my clients. 

My wife, Katie and I have been married for 34 years, and we enjoy our four children. The life experiences of raising a family help provide the foundation for a financial relationship built on practical experience.  


Jessica S. Klintworth

I have over 15 years of banking experience. I have fulfilled several positions from Teller/New Accounts to Vice President Banking Center Manager. My passion for Investment Banking and Customer Service led me to my current role with First State Bank and Trust as a Client Service Specialist in the Investment department.

I grew up in Nebraska and attended the University of Nebraska, Lincon where my husband Chad and I met. After short moves to Kansas City and then onto Montana for several years, our family moved back to Nebraska to be closer to extended family. Our son Camryn attends the University of Nebraska, Omaha pursuing an Electrical Engineering degree and our daughter McKinzie is a Nanny in Pennington, New Jersey. I am excited to be a part of the Fremont community and extend my love for volunteering. My hobbies include reading, knitting, and spending time outdoors golfing, hiking, biking, and rafting with my husband and two children.

Look forward to meeting you!
