Dr. Chawla is excellent! He saw my Mom for an issue last summer and did an excellent job. He saw me this year in January for terrible unrelenting heartburn and outlined an excellent treatment plan. I was 100% reassured and confident. I would recommend him highly to everyone and would always trust him with my family's needs going forward. Great office staff. Highly responsive. Strongly recommend this physician.
