Expert eyes. Real people.

Known to many patients as “Dr. Tim”

​​​​​​​Dr. Trinh founded All EyeCare Optometry in 2010. He earned his undergraduate degree in biochemistry at UCLA in 2003 and his Doctor of Optometry at UC Berkeley in 2007, followed by a residency in ocular disease at the Fresno Veterans Affairs Hospital. He became a Fellow of the American Academy of Optometry in 2010 and received the California Optometric Association’s George I. Dean Leadership Award in 2007.

His clinical interests include chronic dry eye, specialty contact lenses for keratoconus and eyes that have undergone surgery, and myopia management for children. His approach reflects a central belief at All EyeCare: vision is more than 20/20. Understanding eye health, visual demands, and how the eyes work together helps guide care for both routine needs and challenging cases.

Dr. Trinh also co-founded Box Medical Solutions and helped develop the Meibox, a portable imaging system used to examine the eyelids’ oil glands in dry-eye care. Beyond the exam room, he has mentored students exploring optometry and supported youth career and ethics programs. In practice, he emphasizes clear explanations and a conservative approach, helping patients understand their options before choosing treatment.

A thoughtful partner in everyday and medical eye care

Dr. Kull has been part of All EyeCare Optometry since 2024. He studied kinesiology at Iowa State University, earning his bachelor’s degree in 2017. He completed his Doctor of Optometry at the Southern California College of Optometry in 2024, graduating summa cum laude.

His clinical training included rotations at the Bakersfield Veterans Affairs clinic, Family Eyecare in Lemoore, and Cedars-Sinai. He brings that varied experience to a thoughtful, individualized approach to eye care, with an emphasis on listening and building lasting relationships with his patients.

At All EyeCare, that means taking time to understand how you use your vision, what feels comfortable, and what you hope to improve—whether you are visiting for an eye exam or exploring contact lenses.

Outside the office, Dr. Kull enjoys tennis, discovering local restaurants, and time with family and friends.
