I have to give a recommendation for Dr. Darren Geyer over at Premier Family Physicians (Southwest Parkway). He's not an Ag, but I've been going to him for years and been very happy. The staff at Premier is very good and his personal staff there is excellent. In fact, when my wife's primary care retired she made the switch to Dr. Geyer last year and has been really pleased.
One of the other advantages I like about Premier is that their location in Southwest Village lends itself to other appointments with other specialists who practice in the same building. That has made appointments for much easier now that a number of my docs (neurologist and GI) are all in the same building.
I can't speak highly enough of Dr. Geyer. He's very laid back, takes time to get to know you and really work with you on whatever may be the problem. His team shares the same mindset/attitude.
