Grand Rapids Travel Clinic Our Grand Rapids office is conveniently located just north of the pedestrian walkway at Calvin College. You will find the office very inviting and convenient to find and park. Gayle Heys, R.N. I am a registered nurse who retired from Amway Corporation. In that position I wrote the protocols for travel health and facilitated the program for their employees who traveled internationally. I joined Passport Health of Michigan in 2010, and I have found it to be a very enjoyable experience to learn of others’ destinations and to teach them how to stay healthy and safe during their travels. I, too, like to travel and I’ve gained way too many ideas for trips according to my husband.
