Her office staff is efficient and friendly, no long waits for appointments and she never rushes through your visit. Great doctor!

Excellent. I was sent to Dr. Greiner from my primary physician for AFib. Dr. Greiner has a very "calming" demeanor, and is very thorough. I feel totally confident I am under great cardiovascular care, and have a clear understanding of my heart condition. She takes the time to explain things in layman's terms. Also, she, and her awesome staff are very punctual. Very impressive.

I have been seeing Dr. Greiner since December 2011. She performed a angiocath which luckily, proved negative, & has been taking care of me since. She is calm, confident, reassuring & timely. When I have a question or concern, I can post a question via the patient portal & she answers my question by the next day. Her home office is in San Antonio but since I live in Kerrville, I am able to see her in her satellite office in Comfort. Her staff are efficient and courteous. She is perfect!
