Bill Dennis, President & CEO

Bill leads our team by offering workshops in stress management and practice building as well as facilitating of our groups. He is passionate about supporting clinicians, leading our retreat program and workshops at our retreat center, Villa Serena. He also thrives on leading our team and in creating success for health and wellness providers.

Bill originally founded Practice Success as an effort to introduce integrative coaching and consulting to clinicians. He believed that the time had come to ‘reinvent’ the health industry by creating networks of likeminded, forward-thinking individuals - starting in greater DC and NYC. As they began to work together, these interdisciplinary, collaborative groups
began to expand the perspectives of its members. This offshoot project eventually evolved into a thriving program, now known as Metro Collaborative. It has attracted various health professionals looking for new techniques to expand their businesses and connect with other innovators.

Observing the notable progress members were making within these forums, it quickly became clear that business acceleration groups were on the cutting edge for problem-solving, as well as professional solidarity and connectivity. Indeed, these groups provide ways for business owners, physicians, dentists and practitioners of all disciplines to learn, connect and collaborate to create cross-referral opportunities.

The Path to Metro Collaborative

Bill's background is extensive and spans several decades. In New York City, he worked as a psychotherapist and stress management consultant, coaching executives, physicians, and dentists on maintaining work/life balance. He extended this practice into coaching physicians on improving their business models by focusing on integrative methods for success,
such as ‘client-centered communication.’

Completing a degree in psychology and humanities at Carnegie Mellon University, Bill worked as a biofeedback therapist, meditation teacher and coordinator of services at The Combined Therapy Program of The Himalayan Institute. He then completed a Masters in Counseling Psychology at the University of Pittsburgh. Bill moved to Greenwich Village to open The Center for Holistic Medicine in 1978 with Rudolph Ballentine, MD, practicing psychotherapy and stress management consulting. After starting a family there, he began modernizing dental and medical offices throughout the North East through the introduction of technology.

Over the last few decades, he has evolved his contribution to the healthcare community, always maintaining his focus on leadership, technology, and team building. In the intervening years, he served at the Seltzer Institute, Coaching Solutions, among others. He founded Coaching Solutions (2000-2009), a collaborative practice management firm that implemented transformation with a broad team-based approach to complex business issues.

He has taught at The NJ AGD and has lectured at The Academy of General Dentistry, the Tufts and NYU Dental Schools, and numerous study clubs around the country. From participating at Shalom Mountain Retreats, serving as President of The Center for Conscious Living and the Team Management and Leadership Program at Landmark Education, he has learned to envision and generate transformation. Last year, he lectured on leadership at the Cleveland Dental Society.

Bill and his wife live their passion by leading retreats, wellness programs, and workshops in Bethesda, MD and at their retreat facility, Villa Serena (Dominican Republic). He splits most of his time between New York City, Philadelphia, and Washington DC. He resides in Bethesda, Maryland, and enjoys skiing, yoga, and spending quality time with his sons and stepsons.

Lakshman Nirmalwad, Data Analyst

Lakshman graduated with a Bachelor of Commerce from Mumbai University in 2007. 
While there, he realized his innate attraction to accounting, economics - and really numbers in general.

There was a certain ease to calculating - it spoke to him. Macro and micro economics were interesting and fun; figuring out numerical problems and their relation and application to the real world were fascinating and practical -  a passion he considered important and worth cultivating.

Today, he applies his love for calculations and numbers to Metro Collaborative - working "behind the scenes" to help it thrive on a number of "backend" levels.
