Dr. Modarres earned his Bachelor of Science in Neurobiology and Physiology from the University of Maryland at College Park in 2001, where he also founded the first pre-dental society at the university. As an undergraduate student, he also worked as a dental assistant while simultaneously putting in hours as a student researcher. He completed his Doctor of Dental Surgery at the University of Maryland School of Dentistry in 2005.

After graduating, Dr. Modarres began his one-year General Practice Residency (GPR) at the Lehigh Valley Hospital-Muhlenberg in Allentown, Pennsylvania. After completing his GPR in 2006 and practicing a wide variety of services, including simple and complex extractions, bone and soft tissue grafts, dental implants, and more, he decided that periodontology would be his specialty. In 2009, he completed his 3- year periodontics and surgical training at Nova Southeastern University in Ft. Lauderdale, Florida. From there, he moved back to Maryland and started his 2-year implant periodontal prosthetic fellowship, in which he focused on comprehensive treatment planning, full mouth reconstructions, and other complex restorative treatments.
