Meet Dr. Alexandra Otto
As both a board-certified pediatric dentist and a mom of two young children, Dr. Alex Otto understands what families need from a dental home. She founded her practices with a clear purpose: to provide pediatric dental care that is preventive, evidence-based, and centered on the child rather than insurance or sales-driven treatment.
Early in her career, Dr. Alex saw how often families felt rushed, confused, or pressured during dental visits. Parents waited too long, received limited explanations, or were told there was only one way forward. Dr. Alex knew families deserved better.
At Steiner Ranch Pediatric Dentistry, every recommendation is proactive, supported by science, and tailored to your child’s unique needs. Dr. Alex takes time to explain options clearly, respects parental instincts, and ensures treatment is never more than necessary. Her approach blends advanced technology, cosmetic-focused pediatric dentistry, and a calm, reassuring presence that helps children feel safe and confident.
Whether she is placing a zirconia crown, performing a laser frenectomy, helping a nervous child relax with nitrous, or walking a parent through treatment decisions, Dr. Alex’s mission remains the same: to serve families with honesty, safety, and heart.

Insurance Made Simple
We believe dental care should feel clear and stress-free, especially when it comes to insurance. Steiner Ranch Pediatric Dentistry is a fee-for-service practice that works with most PPO insurance plans.
Our team is happy to help you understand your benefits, review estimated costs, and answer questions before your visit. While we do not accept Medicaid, we are committed to transparency and helping families feel confident in their care decisions.
If you have questions about your coverage or our approach, give us a call. We are always happy to help.
Benefits of Fee for Service
Our fee-for-service model allows us to focus on what matters most: providing high-quality, personalized care based on your child’s needs rather than insurance limitations.
This approach gives families greater freedom to choose care based on trust, experience, and long-term outcomes. Treatment recommendations are guided by clinical expertise and your family’s goals, not network restrictions.
Freedom of Choice
This model also gives families more freedom to choose a provider based on quality, trust, and experience — not just an insurance list. You can make decisions based on what’s best for your child’s health, not what’s covered by a network.
