Wendy Prestwood and her husband Mark opened Prestwood Financial Group in 2007 because she saw a need for a financial services group that stood for integrity and insightful investment options.

Developing and implementing personalized financial plans for her clients is a top priority at Prestwood Financial Group.

Wendy is highly involved with her three children and their activities. Her oldest son Jordan also works with her at Prestwood Financial Group. Wendy loves to be active and especially enjoys a round of golf whenever possible. As a “foodie”, she loves sharing her culinary creations with friends and family.

Mark Prestwood decided to become a financial advisor after discovering a growing need in the retirement market for professionals that provide a sophisticated analysis and planning for individuals and families. Previously a small business owner, Mark took the opportunity in 2007 to open Prestwood Financial Group with his wife Wendy. He appreciates clients that are willing and eager to learn from his experience. The ability to plan and educate his clients on both opportunity and risk for major decisions is what makes the job so worthwhile.

When not working, Mark prefers to spend time relaxing with his wife and kids. He hits the gym whenever he can to maintain a healthy lifestyle. Mark and his family enjoy outdoor activities on their land in southeast Kansas. He provides comic relief to his wife during the occasional round of golf.
