Financial Advisor | CERTIFIED FINANCIAL PLANNER™ Professional

Steve 1

I was raised on a dairy farm in Jasper County and even though I had a great childhood, I knew that milking cows for the rest of my life was not for me.   I saw my dad not miss a milking for over a decade to make sure my siblings and I had opportunities he never enjoyed (I am the youngest one in the picture).  We learned first-hand the discipline and focus it takes to finish a job no matter the difficulties you encounter.  My parents worked very hard on that farm, and they taught us what it takes to fulfil your dreams.  I met my beautiful wife Jodi in college and we started making dreams of our own.  Jodi teaches 3rd grade at Dieterich grade school and also runs a college consulting business on the side, Achieve with Jodi.  We have 3 amazing children – Mark 24, twin daughters Jordan & Rachel age 22.  Yes that’s right – we had 3 kids within 3 years.  They have all recently moved back home from college, but they are all 3 EMPLOYED!!

I grew up in a sports family and our favorite sport was whatever was in season.  My two older brothers were setting school records and winning championships and I wanted nothing more than to do the same.   I loved basketball, but was fortunate to win the state in the high jump and earn a track scholarship.  Track was my ticket to college, but after an injury I soon realized that I was better with numbers than staying healthy.  (I’ve had multiple knee surgeries and have the HONOR of being the youngest double knee replacement for Dr. Bonutti at age 45.)   I still golf and love sports, but eventually realized that finance was my REAL calling, where I really could help people.

After graduating from Eastern Illinois University in 1990 with a Bachelor of Science degree in Finance, I moved to St. Louis and obtained my securities license.  After a year in the “city”, my high school accounting teacher told me that Peoples State Bank was looking for someone like me.  This led to me starting the investment center for the bank.  In 2003, I completed my degree from the College of Financial Planning and became a CERTIFIED FINANCIAL PLANNER™ professional.  This certification requires a broad understanding of investments, insurance, taxes and estate planning strategies including trusts.  I truly enjoy the personal relationships involved in financial planning and love to develop a plan that fits my client’s situation.

I fortunately decided to affiliate with Commonwealth Financial Network in 2017.   It has been a wonderful decision to partner with an independent firm with so much to offer.  They offer a unique networking experience designed to help hone my expertise, share best practices, and provide ever-higher levels of service, education, and leadership to my clients.

I was born and raised near Wendelin, Illinois.  This small town is known for Vic’s Café/Tavern and the Holy Cross Catholic Church.   I became a Jasper County resident when I married my husband, Kevin Kocher on March 26, 1988.

We have two adult children—Kelsey & Jordan—well actually three if you count my spoiled dog, MAX (Havapoo short for Havanese Poodle).  Our kids both joke that Max is the favorite child and all the inheritance will go to him someday!!  Kelsey works at Pacific Cycle, Inc. as Cash Application Supervisor in Olney, Illinois and we are lucky to have her back living at home.  Jordan works as a Physical Therapist at Rehabilitation & Performance Institute in Owensboro, Kentucky where he also lives with his wife Skylee.  At this time, I have two grand dogs, Milo (Schnauzer) & Theo (Goldendoodle short for Golden Retriever Poodle).

I graduated Olney Central College in 1988 with an Associate degree as Administrative Assistant.  I actually started working at Peoples State Bank as an intern in the accounting department my last year of college.  It didn’t take me long to realize that I was a people person, so I moved from accounting to the teller department.  My husband would probably say, people person means I like to talk too much!!

In 2002, I took advantage of an opportunity to work with Steve Mammoser in the investing department.   Back then, I had no idea what a wonderful learning opportunity this would be, especially from a Certified Financial Planner™ like Steve.     A lot of work & time goes into making a financial plan for a client.  Just think about it this way, we are all created differently and not one of us is created the same.  With that being said, each plan is individually prepared with you, the client in mind.  Why not take the opportunity to come meet the staff at Peoples Wealth Management to see how we can help you with all your retirement and investment needs.

Ok a little more about me, to relax I love to drive in my jeep with the music up loud.  Yes I am one of those people, that are singing and dancing in their cars, please do not judge until you try it!!  I also love to spend time with my husband Kevin my dog Max, and my other two children that is when they have enough time for their old mother!! 

I have a total of 30 years of investment and banking service experience, along with my life and health insurance licenses.  With my extensive investment service knowledge, I look forward to meeting with you and your family to help with your investment needs.

My husband and I moved back to the area in 2013 after spending 5 years in Lawrenceville, IL.  Although we are thankful for our time there, we realized the importance of family after having a child of our own and jumped on the opportunity to move back closer to home.  Originally from Teutopolis, my husband, Josh, and I planted our family’s roots in Newton, his hometown.  He came back to serve as a teacher and coach of jr high baseball and basketball, and now is a school administrator in a nearby community.  We now have two children who are an inseparable pair and keeps us on our toes.   Ava is our 7-year-old who has a huge imagination and loves to learn, play outside, and is quite the little artist.  Hudson is our 4-year-old who would live on sweets if we would let him and loves taking over his sister’s toys, playing outside, and can melt your heart with his compliments and affection.

I started my college career at Lake Land College and graduated with an associate’s degree in Business Administration.  I then continued on to Eastern Illinois University to earn a bachelor’s degree in Business Marketing.  I realized during college, as I was taking accounting, finance, and other mathematical classes, that I was best suited for the “numbers world”.

I come to Peoples Wealth Management with a broad background in investments and accounting.  My main role and commitment is helping clients and making their experience as seamless as possible.  Outside of work, I enjoy spending time with my family and friends, being outdoors, crafting, and my husband may say I have a slight shopping problem.  As my daughter is starting to get into extracurricular activities, I have helped coach her soccer and baseball team.  I have gotten to know her classmates and friends better and I am proud to be a part of something she enjoys doing……. while she will still let me!  When we need a break from our busy schedules, we look forward to a Gulf Shores vacation with family every year.  I consider the beach my “happy place” and it’s nice to not make any plans for the week, relax, and just let the kids play.  I love meeting new people and I look forward to getting to know more people in this community I now call home.
