I've been going to Dr. Mehta for several years and have been extremely happy with the care and treatment he's provided. He's helped me get my lupus under control and I have been feeling great. I appreciate Dr. Mehta listening to what I need and making sure everything is in check.

Dr. Philpotts is very attentive, thorough caring and listens to all my mom's concerns. If it wasn’t for him we wouldn’t have found the diagnoses for my mom and get her the care she needs. The office is always clean and the staff is always friendly and welcoming. I’ve heard horror stories from people about their Rheumatologist. But, I will definitely say going to Southland Arthritis and seeing Dr. Philpotts is a breath of fresh air and we’ll continue to get treatment here for the foreseeable future. Thank you for all that you do for your patients.

Everyone here was wonderful – from the front desk, to Dr. Bravo and her assistant. They all put me at ease. Dr. Bravo explained my lab results in both technical terms and in terms a lay person would understand. Wait times were short. This doctor visit was a very pleasant experience all round.
