John S. Kellogg, MD, MS - SOUTH BAY ALLERGY AND ASTHMA GROUP, INC.

I moved to the SJ and found Dr. Kellogg through Google! Dr. Kellogg was very on time. He’s very knowledgeable and the office was very very efficient and fast when it came to receiving my allergy shots from across the country. The office is clean and staff are nice! You have to wear a mask which makes people like me feel safe in case someone starts coughing. Over all 5/5!

I hope there are so many more of Dr. John Kellogg out there. I love how friendly, thorough, care, patient and knowledge Dr. Kellogg was. His staff was also very friendly and wonderful. I came to Dr. Kellogg for my ongoing itch issue. The first meeting, he spent more than an hour to go over my health history. Then, he shared with me the plan on how to tackle the issue and opened for my inputs. My second meeting was also as good.

Extremely great M.D.!! He's so attentive and takes his time to find what is wrong great great service
