in Houston, TX |
She is through in the time she spends with you. Never feel rushed. The visits are always on a two way discussion. If I agree or disagree. There is nothing I can't discuss. Encourages classes to help me better aid my health. Sugar detox which I was not crazy about has helped me. Plant based food has also aided in my health. I am eating healthier than before. Never had a complaint about her staff. The ones who have been there longer are like old friends. New staff are friendly and kind.

She is competent, thorough, spends time with her patients, explains things, and encourages healthy living.
in Houston, TX |
Dr. Serna is all about listening to my health problems, and she treats accordingly. She is always willing to change a medication that could be troublesome with side effects, and concerned about cost. Dr. Serna has been my Dr. for many years. She gives classes in her office for living a better lifestyle, has increased my medical knowledge, and even shared wonderful healthy recipes. I truly believe there is not a more caring Dr. in all of Houston.

She is very thorough and also consider my opinion. I value her advice always. She has excellent bed side manner. Thank you Dr Serna
in Cypress, TX |
Dr. Serna actually takes the time to listen to me (the patient). She addressed all of my concerns and made a recommendation or some sort of action plan for each concern. Then when I had a follow up visit she actually looked at the notes from the previous visit to see how that problem or concern has progressed or is resolved. She provides practical solutions and works with me on what I am willing to try (medicine, PT, no medicine, etc). I love her holistic approach before going to meds.
in Houston, TX |
Dr. Serna goes beyond the normal process of check-ups and office visits, by encouraging personal responsibility and taking charge of your own health.
in Houston, Texas |
Dr. Serna is an excellent Doctor. My husband and I have not come across any other doctors who take the time, make sure everything is documented, review what was documented and then to provide a printed report of the office visit, instructions and medication prescribed and follow up.
in Cypress, TX |
Dr. Serna is communicative and knowledgeable. She takes extra time and effort to make sure you are included in plans, diagnosis, and treatments. She is on top of my medical history and aids in future treatments.
