Our Team

Dr. Scott Sitterle founded Sitterle Vision Source & Dry Eye Center in the Thousand Oaks area of San Antonio in 1994 with a vision to deliver medically focused, prevention-driven eye care to the community he calls home. With over three decades of clinical experience, he is recognized for his expertise in dry eye disease, ocular health, and the critical role nutrition plays in preventing and managing chronic eye conditions.

Dr. Sitterle earned his Doctor of Optometry degree from the University of Houston College of Optometry in 1990. He is licensed as an Optometric Glaucoma Specialist and is certified in the diagnosis and treatment of eye disease, injury, and infection. Throughout his career, he has emphasized comprehensive medical eye care and long-term disease prevention.

Dr. Sitterle has a special interest in treating dry eye disease and ocular surface inflammation. He believes that chronic dry eye is often a systemic issue — not just an eye problem — and that successful treatment requires a deeper understanding of inflammation, lifestyle, and nutrition.

He works closely with patients to address:

• Meibomian gland dysfunction (MGD)

• Chronic dry eye syndrome

• Ocular rosacea

• Inflammatory eye conditions

• Early macular degeneration

His approach blends advanced clinical treatment with foundational health strategies designed to reduce inflammation and support long-term ocular wellness.

Dr. Sitterle is passionate about educating patients on the relationship between nutrition and chronic disease. He believes that many eye conditions — including macular degeneration, cataracts, diabetic eye disease, and dry eye — are influenced by systemic inflammation and nutrient deficiencies.

He regularly counsels patients on:

• Anti-inflammatory nutrition

• Whole-food supplementation

• Preventative strategies for ocular disease

• Lifestyle modifications that support retinal and ocular surface health

His philosophy is centered on empowering patients with the knowledge and tools to take ownership of their long-term vision and overall wellness.

A long-standing member of the San Antonio community, Dr. Sitterle has been active at Community Bible Church since 1993, where he plays trumpet in the praise orchestra. He has also served as a board member and past vice president of the Northeast San Antonio Rotary Club.

Outside the office, he enjoys spending time with his wife, Gloria, to whom he has been married since 1990. They have two sons, Philip and Clifton and are now expecting two grandaughters this summer! Dr. Sitterle loves music, sunshine, and relaxing near the water — whether at the beach, lake, river, or pool.

Dr. Nicole Maldonado is a San Antonio native and therapeutic optometrist who focuses on advanced dry eye treatment and myopia control for children.

As the co-owner of Sitterle Vision Source & Dry Eye Center, she and her team have built a modern, medically focused optometry practice dedicated to solving root causes — not just prescribing quick fixes.

After graduating from O’Connor High School, Dr. Maldonado earned her Bachelor of Science in Biology from St. Mary’s University in San Antonio. She then completed her Doctor of Optometry degree at the University of Houston College of Optometry, where she trained extensively in ocular disease, retinal pathology, and medical eye care. Her externship experience includes the Robert Cizik Eye Clinic at Memorial Hermann Hospital and the South Texas Veterans Administration, where she developed a strong foundation in complex eye disease management.

Today, Dr. Maldonado is known in San Antonio for her expertise in treating chronic dry eye disease, meibomian gland dysfunction (MGD), ocular rosacea, and recurrent styes and chalazia and she offers advanced in-office treatments including:

• Intense Pulsed Light (IPL) therapy

• Radiofrequency (RF) treatment

• Low Level Light Therapy (LLLT)

• Amniotic membranes

• Prescription and customized medical management

Her philosophy is simple: Dry eye is a medical condition that deserves medical solutions.

In addition to dry eye specialty care, Dr. Maldonado provides evidence-based myopia control treatments for children and teens, including MiSight® 1 day contact lenses, orthokeratology (CRT), Stellest™ lenses, and low-dose atropine therapy. As both a doctor and a mother, she is deeply committed to protecting children’s long-term vision and reducing the risk of future sight-threatening complications.

Dr. Maldonado believes patients deserve to feel heard, educated, and empowered. She is passionate about clear communication, innovation in clinical care, and building a team culture focused on confidence and excellence.

When she is not in the office, she enjoys spending time with her husband and three-year old son, running, reading, volunteering/working on meaningful soul-fulfilling projects, and of course — cheering on the San Antonio Spurs.

Dr. Julia Groom is a therapeutic optometrist at Sitterle Vision Source & Dry Eye Center in San Antonio, Texas. She provides comprehensive eye care for patients of all ages, with a focus on helping patients understand their vision, eye health, and treatment options.

Dr. Groom earned her Doctor of Optometry degree from the University of Houston College of Optometry in 2026. During her clinical training, she completed externships with the South Texas Veterans Health Care System and Sharp Eye Consultants, where she gained experience in comprehensive eye exams, medical eye care, ocular disease, and the diagnosis and management of a wide range of eye conditions.

Dr. Groom enjoys caring for patients with a variety of vision and eye health needs, including routine eye exams, glasses and contact lenses, dry eye, and medical eye conditions. She believes great eye care starts with listening and taking the time to make sure patients feel comfortable, informed, and confident in their care.

Most of all, Dr. Groom values building lasting relationships with her patients and looks forward to becoming a trusted part of their eye care for years to come.

Outside of the office, Dr. Groom enjoys life in San Antonio with her husband, golden retriever, and two cats. In her free time, you can probably find her trying out one of San Antonio's newest coffee shops.
