Between the two of them, and just a few elite, highly-trained staff, you have your complete Vanguard team. You will always know who you're working with, and that they are uniquely qualified to help you and your staff reach your practice goals.




Judy Marcus - President


Judy Marcus has worked in the areas of organization and personnel management, marketing, sales, and finance for over 30 years. More than 27 of those years have been spent helping general dentists in practice. She is undoubtedly one of the most experienced and tenured professionals currently in the industry.


In 1989 she and her husband started a dental seminar and training company, where Judy was a keynote speaker and executive in charge of operations.


When they founded Vanguard Dental Management, their goal was to create a different kind of company, one that would provide practice owners and their staff with personalized consulting and assistance in order to help them rapidly achieve their goals for practice growth and profitability, in a way that was accessible and affordable.


As the President of Vanguard, Judy has developed the majority of the training materials, protocols and procedures for her dental practice clients. She has personally worked with hundreds of practices, bringing them the benefit of her insight and compassion, as well as her vast knowledge and years of experience. With her help, many of these practices have become “million dollar practices” and beyond.


Judy knows exactly what is necessary for a practice to achieve its potential, from whatever level they are starting. She has helped practices start from scratch and become highly productive and profitable within just a few months of opening.


Judy’s clients value the time she spends with them, the personal care and attention she gives them, and her steadfast dedication to their success. Judy prides herself on never giving up on helping a client, no matter how difficult or complicated their situation may appear to be. She wants every Vanguard client to know they can count on her to help them to the very best of her ability, and that she will be there to assist them with any of their practice concerns or questions.







Ingo Mahn, DDS - Executive Vice President and Practice Mentor


Ingo Mahn, D.D.S graduated from the Marquette University School of Dentistry in 1985. He became a client of Judy Marcus and her team in 1995.


When Dr. Mahn started with Judy, his practice was collecting $15,000 per month. Within a year of working with and implementing the Vanguard system, Dr. Mahn was seeing 40 quality new patients every month, and collecting over $100,000. 90% of his new patients were now accepting and paying for all the care they needed. Low paying insurance plans were removed from the practice. His office staff were well-trained, and had become a strong and stable team.


For over 10 years, Dr. Mahn's practice continued to steadily grow. He then added an associate, who later became his partner. She also went through the Vanguard program at Dr. Mahn's advice.


His practice continued to increase to over $200,000 production and collections per month, and eventually peaked at more than $300,000 per month. All of this was accomplished working no more than 4 days a week, and sometimes less.


Dr. Mahn built one of the most successful private dental practices in the country, one that consistently grew and improved for many years. After over 30 years as a general dentist, with all of his financial goals accomplished fully through his practice,

Dr. Mahn retired from dentistry. He turned his practice over to his partner so that she could pursue her own goals and direction, and joined the Vanguard team.


Throughout his career Dr. Mahn has kept at the cutting edge of clinical knowledge and expertise. He has trained and studied at respected institutes such as: Pete Dawson, the Las Vegas Institute for Cosmetic Training, The Spear Education Continuum, Gordon Christensen courses, and many more.


Dr. Mahn has maintained his dental license in multiple states, and still attends numerous seminars and conventions to keep up with the advancements in his field.


As the Executive Vice President and Practice Mentor, Dr. Mahn brings a unique "insider" view to the effective implementation of the Vanguard system in a dental practice. He has fully experienced the ins and outs of growing a general dental practice as the primary care provider, and as such is able to help guide clients through the steps necessary to reach their practice goals with a very real and level understanding of what a dentist and practice may go through along the way.
