Why Patients Love Dr. Gross and Our Team

Dr. Gross is here when you need him. He and our other eye doctors are available 24/7 for emergency care. 

Dr. Gross is board certified. So are Dr. Nelson and Dr. Taffora. To become board certified, a doctor must pass a rigorous examination process and demonstrate an elevated level of knowledge and skill in their specialty. They must also demonstrate a deep commitment to patient care and successful treatment results to prove it.

Dr. Gross cares. For our doctors, the number-one goal is to help you enjoy excellent vision and a better quality of life. Dr. Gross will take the time to sit down with you and discuss your concerns, then work with you to develop the most effective treatment plan.

Dr. Gross accepts insurance and financing. He and our team want to keep services affordable so you can receive top-quality eye care when you need it most.

Dr. David Gross has performed more than 25,000 lens implant surgeries and 35,000 cataract surgeries over the last 25 years. He was one of the first ophthalmologists to combine surgical treatment of cataracts and vision-restoring intraocular lenses. This is now one of the most commonly used treatment methodologies for patients with cataracts.
