Africa and Ireland Travel Specialist

I took my first real big trip abroad when I studied in Europe in law school in 1994.  I put a backpack on my back and traveled before my classes started in Ireland.  I spent time in London, Greece, Italy, Austria, Germany, France, Amsterdam, Switzerland, Ireland and the Czech. Republic that summer.  It took 20 years before I was able to go back to Europe.  But my passion for travel was re ignited in 2014 with my fabulous trip to Italy. I decided then that I loved to plan and research vacations.  The travel bug hit me hard!  Slowly I started to do all my own research.  An idea came to me as I planned my daughters senior trip to Greece this spring.  It crystallized as I spent some time in Mexico with my family in June.  I wanted to become a travel agent.  Spring forward to now.  On a Whim Travel, LLC is a reality.  

I am an independent contractor with RSVP Events & Travel (https://rsvpeventsonline.com and http://stlouismo.vacation.travelleaders.com).

I am so excited to have the partnered with Marcie and her team. I am certified as a South African Travel Agent, an Ireland travel agent, a Mexico travel agent.  I continue to learn and expand my knowledge base. Every chance I get I am trying to learn as much as I can.  The thought of helping people plan their adventures sounds incredible.

My Travel Stories



As we set out for Zimbabwe it wasn't the trip we had hoped for..our bush plane couldn't fly due to the rain, so it was a long overland journey first in a bus and then in a safari car with Bee our guide. A safari car has "African Air conditioning" and... Read more from my Zimbabwe story.

Rwanda...It touched my soul

We were greeted after almost 24 hours of traveling by Aimable who met us at the gate and was so gracious and escorted us through immigration. He delivered us to the capable hands of Herbert who has been wonderful.  I learned about Herbert and his history. He was 13 in 1994.... Read more from my Rwanda...It touched my soul story.

Ireland and the traffic circles

I can never decide if I could live anywhere else if it would be Ireland or Italy.  They are my two favorite countries to visit.  Ireland holds a special place in my heart.  I studied there in 1994 for my summer abroad in law school and watched the slow speed chase...

Belize Adventures

Reviewed By Kerry - Aurora, CO | Traveled to Belize ~ Central America
I traveled to Belize during the pandemic and Mary was knowledgeable about how to navigate and all the requirements for travel. Belize was amazing and met every "ask" I had for the destination. Travel was easy and the accommodations Mary arranged were absolutely perfect! If you want an agent who listens and delivers, Mary is your best bet!!
I would recommend this agent to my family and friends
