Dr. Jimmy Nielsen

A renowned name in the dental sphere, Dr. Jimmy Nielsen obtained his Doctorate of Dental Surgery from Virginia Commonwealth University. Since making North Texas his home in 2009, Dr. Nielsen has significantly contributed to the local dental community. He first established Van Alstyne Dental in 2010, bringing his expertise to the area. Following this success, he further expanded his professional reach by founding Nielsen Dental Studio in Celina, TX, in 2013, continuing to provide exceptional dental care and services. From working in prestigious Arizona practices to providing services at free clinics, Dr. Nielsen's journey is emblematic of his dedication. An active member of the American Dental Association, he keeps abreast of the latest in dental advancements. His broad spectrum of general and family dental services is complemented by his amiable nature, making every patient feel understood and valued. Outside the clinic, Dr. Nielsen finds joy in the great outdoors, be it hunting or camping, and takes immense pride in watching his five children thrive in sports.


Dr. Marcus Middlebrook

Dr. Middlebrook, raised in the Northwest suburbs of Chicago, pursued his undergraduate studies at Michigan State University, earning an honors degree in Biochemistry. He then attained his Doctor of Dental Medicine degree from the University of Kentucky, where he was recognized with an Excellence Award in Restorative Dentistry.

Post-graduation, Dr. Middlebrook, alongside his wife and their Labrador, Huckleberry, relocated to Texas to establish their home.

In his practice, Dr. Middlebrook provides a diverse range of dental treatments. He is passionate about helping patients achieve their dream smiles, offering services such as veneers, implants, and Invisalign. Known for his personalized patient care, Dr. Middlebrook combines his love for dentistry with a commitment to offering the highest quality of care.

Outside of his professional life, he enjoys family time, travel, exercise, and, somewhat ironically, indulges in his sweet tooth. Dr. Middlebrook is also an avid sports enthusiast, always ready to discuss anything related to the Chicago Bears or Michigan State sports teams.
