Having worked extensively with Brian Mandrier and The Mandrier Group in my capacity as Organizing Chair of the International Oncology Leadership Conference (IOLC), as well as through my involvement with the Association of Cancer Executives (ACE), I can confidently state that they are a first-class organization that consistently delivers exceptional results. Their flawless planning and attention to detail is evident in every aspect of event management, from initial concept development through final execution and post-conference follow-up. The Mandrier Group's expertise in selecting exceptional venues—whether in Rome, Florence, Vienna, or other international locations—creates the perfect environment for meaningful professional networking and knowledge exchange among oncology leaders worldwide. Their boutique approach allows for personalized service that adapts to each client's unique needs, making them an invaluable partner for any organization seeking world-class conference management and association services.

“I have had the pleasure of working with the Mandrier Group in my roles as a past president of ACE and as Chair of the annual meeting and IOLC. Throughout our collaboration, their team demonstrated exceptional professionalism, organization, responsiveness, and attention to detail.

 The Mandrier Group consistently anticipated needs, communicated clearly, and handled complex logistics with efficiency and care. Their commitment to excellence made a meaningful difference in the success of our meetings and greatly reduced the demands on our leadership team.

 I would highly recommend the Mandrier Group to any organization seeking a dependable, knowledgeable, and dedicated partner for conference planning and association management.”

“Working with Brian on the IMCC InFocus Basque Country in Bilbao highlighted his exceptional approach to event organization. What stands out most is how he combines meticulous rigor with a refusal to settle for the standard way of doing things. He always looks one step ahead, evaluates alternatives, and asks the right questions to elevate the project. His deep industry experience shines through in every detail, ensuring that the attendee is always at the center of the experience.”

“Brian and his team are fantastic meeting management professionals, and I would work with him again in a heartbeat. I had the opportunity to plan a 380-person annual professional society meeting with Brian and his team, bringing attendees from across the U.S. Brian's knowledge of hotels, reception venues, and catering helped us stay on budget and even turn a modest profit. We effectively used the hotel meeting space for the main meeting sessions, breakout sessions, receptions, meals, and vendor/sponsor tabling. Attendee evaluations were overwhelmingly positive, and we used the feedback to improve next year's meeting.

 Brian and his team have been critical in helping the Association of Cancer Center Administrators to function smoothly as a fledgling professional society with monthly board meetings, quarterly online webinars, and an annual meeting that is well-attended. Maintaining our membership, processing meeting registrations and dues, and providing accurate financial reports are all important activities overseen by TMG and help ACCA to stay on track. We also have six active committees, and Brian and his team help coordinate meeting times. I would highly recommend TMG services to another organization! ”
