Meet Dr. Jack Greenan (San Antonio, TX)

Jack Greenan, O.D., received his Doctor of Optometry from Western University of Health Sciences in 2016. Prior to that, he earned his Bachelor of Science in Biochemistry from the University of California, Davis.

Dr. Greenan is an optometrist at EyeTx, with his primary practice location in San Pedro. He specializes in specialty contact lenses, particularly scleral lenses, and enjoys sharing his passion for eye care with his patients.

Dr. Greenan's interest in optometry was sparked by his own experience with eye issues in his early twenties. Fortunately, everything worked out well, and he now enjoys great 20/20 vision. His favorite aspect of being an optometrist is engaging with people and helping them with their eye care needs.

Away from work, Dr. Greenan describes himself as a bit of a nerd, enjoying reading and anything related to science. His curiosity about the world and the universe is limitless. He also enjoys being in the water, perhaps due to his zodiac sign, Scorpio.

I had an excellent/positive/satisfactory experience at Blance Eye Works. From the moment I walked in... , I felt welcomed and well-cared for. The combination of professional expertise and a friendly atmosphere truly sets this practice apart. Dr. Jack Greenan: Dr. Jack Greenan is an outstanding optometrist. He is incredibly knowledgeable and takes the time to thoroughly explain every step of the eye exam and any findings. I particularly appreciate his ability to answer questions clearly and patiently, ensuring I understood my eye health and treatment options. He has a very patient-centered approach, making me feel comfortable and confident in his care. His specialization in [mention if relevant, e.g., specialty contact lenses, scleral lenses, senior vision] is also a significant asset. Rene (Receptionist): Rene, the receptionist, plays a vital role in making the patient experience so smooth. She is consistently friendly, efficient, and welcoming. From scheduling appointments to handling insurance inquiries, Rene is always helpful and goes the extra mile to ensure everything is in order. Her warm demeanor creates a positive first impression and sets a comforting tone for the entire visit. It's clear she genuinely cares about patients. Blance Eye Works (General Practice): Blance Eye Works as a whole operates with professionalism and a commitment to patient care. The office environment is clean and well-maintained. The staff, beyond Dr. Greenan and Rene, are also very courteous and helpful, whether it's assisting with frame selection or processing paperwork. They seem to have a strong team dynamic that benefits the patient. I felt that my time was respected, and the entire process, from check-in to check-out, was seamless.
