Meet the Summit Ag Insurance

Jeff Dominisse

Crop Agent/Manager


I am a Business Partner and Manager of Summit Ag Insurance.  I work with clients in Nebraska, Iowa, and South Dakota.  Since 1997, I have been involved in the crop insurance industry.  Over the years, I have seen many changes to the industry and work with clients to help make vital decisions for their operation.

I  am a native of Cedar County Nebraska.  I have always enjoyed rural life and have been fortunate to have been raised in that setting. Being involved in production agriculture and crop insurance has been a great way to appreciate the rural life that I grew up in.

As an agent, I have been assisting clients for 20 years with securing insurance for farm, home, auto, health, and life insurance.  I am the communication between the insured and the insurance company by providing quotes, finding answers to questions, explaining insurance coverage, and reporting claims.  

I began working at Summit Ag Insurance in 2012.  My husband Sean and I have two daughters, Alexandra and Samantha. I am an active member of Grace Lutheran Church, PEO chapter, and a 4-H leader.

Crop Agent/Manager


At Summit Ag Insurance, I assist producers with their precision technology. Farmers are  able to insure their actual acres and use their data for harvesting records. This new technology is very beneficial to the producers.

I attended college at UNL where I graduated with a degree in Ag Economics and Ag Business.  While in college, I was a member of the AGR fraternity.   After college, I returned to my home town of Pender, NE where I farm and am an active member of the Northeast Nebraska Corn Growers Association.  I have been working at Summit Ag Insurance since 2012.

Crop Agent



At Summit Ag, I assist farmers in making their crop insurance decisions that best fits their needs.  My role is to help producers look at insurance on a field by field basis and make the best decision as a whole for their operation.

I am a recent graduate at University of Nebraska Lincoln.  After graduating, I decided to return to my hometown of Wisner.  It is near Wisner that my family farms. Farming has had a strong impact on my life and career, so I am excited to return to the area to help serve farmers in the area.

At Summit Ag Insurance, I enjoy working with clients by presenting them with the information they need to make some of their important decisions, especially with marketing their crops. Each grower is met with on an individual basis to review their personalized field plan.

I began working at Summit Ag Insurance in 2015. My husband and I farm near our hometown of Hoskins where we raised our three daughters and now enjoy watching our grandchildren grow up. I am a past 4-H leader, EMT and Fireman for a volunteer squad.

Personal Lines Agent


I work closely with clients to help educate them about how they can better protect themselves with policies that meet their needs.  Showing someone how they can protect their livelihood is important to me.

I began working at Summit Ag in 2015.  In my free time, I love to spend time with my family and making trips back to my hometown of Winside, NE.  As a family, we spend a lot of time outside together.

Crop Agent


At Summit Ag Insurance, I enjoy working with our clients to accurately report and verify their planted acreage and production.   I love learning new things and always strive to stay on top of the ever changing and growing crop insurance industry.

My husband, Aaron, and I have two children, Finley and Teagan.  We love spending time outdoors and spending time with our extended families.  I began working at Summit Ag Insurance in August of 2019.


I work with agents to report and verify our clients' acres and production to ensure that they are correct. I enjoy learning something new every day to help producers more understand the complexity of crop insurance.

Growing up on a farm outside of Howells, NE before moving into town taught me the importance of hard work. I graduated from Northeast Community College in 2019 with a degree in Business where I also was on their volleyball team. In my spare time, I enjoy golfing, playing sand volleyball, and spending time with my family.
