Meet Marianne Cohan, DDS — a highly skilled and award-winning dentist who has dedicated her career to enhancing smiles and optimizing oral health for patients at Summerlin Dental Solutions in Las Vegas, Nevada. With over 30 years of clinical experience, advanced credentials from the American Academy of Facial Esthetics (AAFE) and the American Academy of Cosmetic Dentistry (AACD), and a genuine passion for her craft, Dr. Cohan has established herself as one of the most trusted and sought-after dental professionals in the region.
We are incredibly proud to be a 19-time winner of The Best of Las Vegas from the Las Vegas Review-Journal — a testament to the exceptional care and outstanding results that Dr. Cohan and her team consistently deliver to every patient who walks through our doors. That level of recognition is not earned through marketing. It is earned through decades of clinical excellence, personal attention, and life-changing results that patients remember and recommend to the people they care about.
Dr. Cohan’s journey to becoming an exceptional dental professional began at the prestigious State University of New York at Buffalo, where she completed both her undergraduate education and earned her Doctor of Dental Surgery (DDS) degree. During her time at the university, she pursued a rigorous academic path that included a minor in periodontics, demonstrating her early commitment to comprehensive dental care and her understanding that healthy gums form the foundation of a beautiful smile.
Her excellence in dental school was recognized with two prestigious awards upon graduation. Dr. Cohan received the periodontics award for outstanding work in gum health and treatment, as well as the operative dentistry award for exceptional skills in restorative dental procedures. These honors foreshadowed the remarkable career that would follow and highlighted her natural aptitude for both the technical and artistic sides of dentistry.
Beyond her foundational dental education, Dr. Cohan has pursued extensive advanced training in cosmetic dentistry and implant dentistry. She has completed numerous continuing education courses, certifications, and hands-on training programs with some of the most respected names in aesthetic dental medicine. This specialized training allows her to offer patients the latest techniques in smile makeovers, porcelain veneers, dental bonding, teeth whitening, and full mouth reconstructions.
Her expertise in implant dentistry encompasses everything from single-tooth replacements to complex full-arch restorations like All-on-4 dental implants, giving patients who have lost teeth a second chance at a complete, functional, and beautiful smile. Dr. Cohan has invested countless hours mastering the art and science of dental implant placement, understanding that these procedures require both surgical precision and aesthetic sensibility. Her extensive training means patients can trust that their implants will not only function properly but will also look completely natural.
Dr. Cohan firmly believes that the field of dentistry is constantly evolving. New technologies, materials, and techniques emerge every year, and she is deeply committed to staying at the forefront of these advances so her patients always have access to the most current and effective treatment options available. Her special focus areas include cosmetic dentistry, reconstructive dentistry, and implant dentistry — fields where innovations have dramatically improved patient outcomes and satisfaction.
This dedication to lifelong learning means Dr. Cohan regularly attends dental conferences, participates in advanced training seminars, and studies under leading experts in specialized areas of dental medicine. She invests significant time and resources into mastering new procedures before offering them to patients, ensuring that every treatment she provides meets her exacting standards of quality and safety.
That commitment extends to the tools and equipment inside our practice. Summerlin Dental Solutions features advanced dental technology including FDA-cleared AI-assisted X-ray analysis, 3D digital imaging, and laser dentistry systems. Dr. Cohan personally selected each piece of technology in our office to improve diagnostic accuracy, reduce treatment times, and deliver more comfortable experiences for every patient. When you visit our practice, you benefit directly from a dentist who refuses to stop learning and a facility equipped with the tools to match her expertise.
Dr. Cohan practices dentistry with the patient as her top priority. She understands that visiting the dentist can be anxiety-inducing for many people, which is why she takes the time to create a warm, welcoming environment where patients feel comfortable and at ease. From the moment you enter our spa-like office, you will notice the difference that a truly patient-focused practice makes.
Central to Dr. Cohan’s approach is patient education. She ensures that every patient is thoroughly informed about their condition and understands all available treatment options before any work begins. She takes the time to explain diagnoses in clear, understandable terms, using visual aids, digital imaging, and demonstrations when helpful. Dr. Cohan believes that informed patients make better decisions about their dental health, and she empowers every patient with the knowledge they need to take an active role in their care.
Collaboration is another cornerstone of her practice philosophy. Dr. Cohan always consults with her patients to develop a treatment plan that fits their unique needs, goals, lifestyle, and budget. She recognizes that every patient is different — some are looking for a subtle enhancement while others want a dramatic smile transformation. Whether you need routine preventive care, Invisalign to straighten your teeth, crowns or bridges to restore damaged teeth, or a complete set of veneers to redesign your smile, Dr. Cohan works closely with you to achieve results that exceed your expectations.
She also understands that cost is an important factor in any treatment decision. Our team will walk you through your insurance and financial options and explain our flexible financing plans — including 0% interest for 12 months — so that budget never stands between you and the care you deserve.
Dental anxiety affects millions of people, and Dr. Cohan takes it seriously. Her gentle chairside manner, combined with thorough communication at every step of a procedure, helps even the most nervous patients feel safe and in control. For patients who need additional support, she offers sedation dentistry options that can be tailored to your comfort level. You are never judged for your anxiety at Summerlin Dental Solutions — you are simply cared for.
As a true concierge dentist, Dr. Cohan takes pride in being available for any and all dental emergencies. She understands that dental problems do not always occur during convenient office hours, and she is committed to being there for her patients when they need her most. Whether it is a sudden toothache, a broken crown, or a dental injury, patients of Summerlin Dental Solutions can rest assured that Dr. Cohan will provide prompt, compassionate emergency dental care to address their urgent needs.
This level of personalized attention extends beyond emergencies. Dr. Cohan and her team go above and beyond to accommodate patient schedules, answer questions promptly, and ensure that every interaction with the practice is positive and stress-free. Our no-rush scheduling philosophy means you will never feel hurried through an appointment or treated like a number. You are a valued member of the Summerlin Dental Solutions family who deserves individualized attention and care at every visit.
Outside of her practice, Dr. Cohan is deeply committed to giving back to the community she serves.
Dr. Cohan is an active volunteer for the Make-A-Wish Foundation, an organization that grants life-changing wishes to children with critical illnesses. Her involvement reflects her belief that making a positive difference extends far beyond the walls of a dental office. She finds this volunteer work incredibly rewarding and considers it a privilege to help bring joy and hope to children and their families during the most challenging times of their lives.
Dr. Cohan also dedicates significant time and resources to supporting local animal rescues in the Las Vegas area. Her love for animals is evident in the compassion she shows toward rescue organizations working to save and rehome animals in need. This dedication to helping animals reflects the same caring spirit that she brings to every patient interaction at Summerlin Dental Solutions.
Beyond her professional achievements, Dr. Cohan is an avid horse rider and breeder with a deep passion for the equestrian world. She previously served on the Board of Directors of the United States PRE Association (USPRE), a prestigious organization dedicated to the advanced breeding and promotion of Pura Raza Española dressage horses in the United States and Europe. The PRE breed, also known as the Andalusian horse, is renowned for its elegance, athleticism, and exceptional temperament.
During her time on the USPRE Board, Dr. Cohan was instrumental in promoting PRE dressage horses and advancing breeding standards to help American breeders produce horses capable of competing at the highest international levels. Her commitment to equestrian excellence extended to her own program, where she maintained an impressive herd of 70 PRE horses actively involved in training and breeding. Managing a program of that scale reinforced many of the same values she brings to her dental practice — patience, precision, attention to detail, and long-term relationships built on trust and mutual respect.
Dr. Marianne Cohan brings a unique combination of technical expertise, artistic vision, compassionate care, and genuine dedication to every patient she treats. Her extensive education, advanced training in cosmetic and implant dentistry, patient-centered philosophy, and commitment to cutting-edge technology make her an exceptional choice for anyone seeking comprehensive dental care in the Las Vegas area.
