Chief Operating Officer

Darren Marabelli

As a Badger state native, Darren brings uncommon experience to the Mercy Dental mission of delivering extraordinary oral healthcare. His professional life began as an engineer in the U.S. Army.  During his military career he completed two tours in the Middle East, supervised engineering projects, and served as a development and training officer. As a civilian, he effectively transitioned his military leadership experience and training expertise into the dental field.

Darren works closely with our teams to create a mission-aligned, extraordinary patient experience at each location. As a proven leader and coach, he provides a transformative impact for those engaged in the Mercy Dental Group Employee Development Program. Our clinical teams love his charismatic personality and his passion for helping them advance private practice care.

Beyond the office, Darren loves to travel, play music, and enjoy his family and their Fox Red Labrador – Raffi.

Director of Operations

Marcie Rauls

For more than two decades, Marcie Rauls has refined her expertise in creating exceptional patient experiences. She leverages her talents through coaching and training our dental teams to consistently deliver that same exceptional experience for every patient.

Her extensive knowledge of dental procedures, insurance, billing management, dental assisting, supply ordering systems, and laboratory procedures gives her unique insight into all aspects of practice management, development, and team training. With excellent communication and relationship building skills, she is an invaluable asset to all of our practices as she helps them achieve success in the communities they serve.

Marcie loves spending time with her husband Dan and their two boys, along with friends and family. A Wisconsin girl for life, summers at the lake are especially priceless!

Executive Assistant

Krysta Wetzel

Krysta is a 20+ year veteran of the dental field from a dental lab and dental assisting to dental hygiene, business start-ups, fiscal and operations management, education, and non-profit work. She excels in professional customer and client relations, problem-solving, process improvement, and business management. Krysta is bilingual, with excellent verbal and written communication skills in English and Spanish. One of Krysta’s unique gifts is her heart to see business and non-profit work collide, both globally and locally, to improve lives. Her passion for dentistry extends into social media, where her creativity helps spark the display of Mercy Dental Group’s culture through positive and fun social media posts. Krysta enjoys running and spending time with her family playing sports, cheering on her four kids, traveling, and being outdoors in her spare time.

Insurance Manager


Jocelyn's decades of experience in dentistry and dental insurance have made her a compassionate leader in patient care, and a perfect fit for our team at Mercy Dental Group. Born and raised in Madison, Wisconsin, she graduated high school in 1996 and has been working in the dental field ever since. She excelled as a patient care coordinator at Middleton Family Dental before earning a promotion to Mercy Dental as the Insurance Manager.

When she's not helping patients get the most out of their dental insurance, Jocelyn loves spending time with her husband and son, seeing friends, and taking long walks with her dog, Lucy. Find her outside whenever and wherever there is warm weather – be that here in her home state or traveling elsewhere.



Kristina grew up helping her parents in their Coast to Coast store, where she first learned and loved accounting. The work ethic established by her parents carried her through earning her BA degree in Accounting from UW Eau Claire, and into her work at Mercy Dental Group. With a diverse range of specialties, including payroll, financials, receivables, and payables, she credits communication skills as the key to her success. Her skills in communication and listening, learning, and adapting also contribute to a team atmosphere where every member has a place.

She calls her role at Mercy Dental Group her "forever job," but when she's not here she loves spending time with family most. She especially cherishes weekends with her grandson, which keep her young at heart, and fishing with her significant other, Dan. Though she is active and loves to challenge herself, lazy days at home with her country views are priceless, to say the least.

We don’t just say we’re different, we live it.
