Fastpitch Coaching Staff

Our coaching staff encourages our athletes to contact their coach directly with questions, concerns, or to relay messages.  Learning to communicate with adults is an important life skill and we welcome that interaction with all of our athletes.  Parents may also contact their daughter's coach with any questions.

You may email any coach by clicking on their picture or name below.  Click here to send an email to the entire coaching staff. 

You may leave a message for one of the coaches by calling the John Marshall Athletic office at 507-328-5330.  For general questions about JM Athletics please contact the Athletic Director Brian Ihrke.
