Q5. Does Dr. Cohan give back to the community?
Yes. Dr. Cohan founded Always Smile, a nonprofit foundation that provides life-changing dental care to underprivileged patients who could not otherwise afford it. Giving back to the community has been a central part of her practice philosophy for over two decades.

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.
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.
