At Columbia, Dr. Goel had an extensive education in didactic and clinical courses, and she enjoyed teaching endodontics to the undergraduate dental students.

Through her vast clinical training at Columbia, Dr. Goel can help the most fearful patients feel at ease and relieved.

During her free time, Dr. Goel enjoys spending time with her husband and family, working out, watching Buckeye games, cooking, and reading.
