Eddy Holtschlag

Office Manager & Marketing Assistant 

Huge fan of looking at all areas of health: Physically, Nutritionally, Mentally, and Emotionally. I also enjoy helping out my family, businesses, and community in any way I can. When that is all smooth sailing I'm playing golf, sand volleyball, frisbee golf, or any sport I can get my hands on. I love the outdoors, sometimes you'll find me at a good camping/hiking spot.
