Dr. Sepideh Rahmani
General & Cosmetic Dentist
Dr. Sepideh (Dr. Sepi) Rahmani is the co-owner of Lincoln Smiles Dental and serves as our lead dentist. With over 15 years of professional experience and a deep commitment to excellence, Dr. Sepi brings a unique blend of international expertise and contemporary American dental practices to our practice.
Educational Background and Experience
Dr. Sepi graduated from dental school in 2007 and spent the next seven years establishing and operating a successful private dental practice in Iran. During those years, she developed advanced clinical expertise in several complex areas of dentistry including root canal therapy, dental implants, orthodontics, and cosmetic dentistry. She worked with patients across the full spectrum of dental needs, from preventive care to complex restorative cases requiring precision and creativity.
Recognizing the value of international education and staying current with modern techniques, Dr. Sepi pursued additional training and continuing education in the United States. This commitment to ongoing learning reflects her belief that excellence in dentistry requires a dedication to understanding the latest research, techniques, and technologies available to dental professionals.
Clinical Expertise and Specialties
Dr. Sepi's clinical strengths span multiple areas of dentistry. Her expertise in root canal therapy allows her to save teeth that might otherwise require extraction, and her implant dentistry training enables her to restore patients' smiles after tooth loss with natural-looking, functional solutions. Her knowledge of orthodontics helps her create beautiful alignments and healthy bites, while her cosmetic dentistry expertise allows her to help patients achieve the smile of their dreams.
Beyond these specialized areas, Dr. Sepi is an excellent general dentist who provides comprehensive care for patients of all ages. Whether a patient needs a simple cleaning, a filling, a crown, or complex multi-step restorative treatment, Dr. Sepi approaches each case with careful planning, technical precision, and attention to creating natural-looking, durable results.
Philosophy of Patient Care
Dr. Sepi's approach to dentistry is rooted in a simple but profound principle: she provides each patient with the same level of care and attention she would want for her own family members. This means taking time to understand each patient's concerns, explaining treatment options clearly and thoroughly, and recommending only the treatments that are truly necessary and appropriate for that individual's situation.
She believes that patient education and communication are essential components of quality dental care. Rather than making unilateral decisions about treatment, Dr. Sepi works collaboratively with her patients, ensuring they understand the "why" behind recommendations and feel empowered to make informed decisions about their dental care.
Personal Mission
Dr. Sepi is passionate about creating beautiful, healthy smiles that improve not just how people look, but how they feel about themselves. She understands that a healthy smile affects how people feel during important moments in life, whether that's a job interview, a wedding, or simply feeling confident in social situations. She is motivated by the opportunity to make a meaningful difference in her patients' lives through excellent dental care delivered with genuine compassion.
Why Choose Dr. Sepi: Her combination of international training, extensive clinical experience, and genuine commitment to patient-centered care creates a dental experience that is both clinically excellent and deeply personal.
