What patients say on Google
“Jaden is one of the quiet super heroes of the Cornerstone Office! I recently had a unpleasant experience with another provider, and this office swooped in and saved the day like the "Justice League" that they represent! My experience left me traumatized of needles, and not so trusting of the medical profession. Jaden, with her calming demeanor, soothing voice, and witty personality, distracted me enough so that the nurse could not only obtain my vitals, ask my needed response and answers questions, all while administering the shot I needed. It sounds problematic, but everything ran so smooth, without interruption and, not one person was out of place. This practice continues to show me why all their reviews keep them at a stellar level, and why mine will consistently lead the charge! Thank you Cornerstone for continuing to demonstrate through your entire staff what loving your craft looks like.”
“Finally! A place that actually spends time with people! It’s a miracle! Dr. Flanagan is the most knowledgeable and compassionate doctor I’ve seen since moving to Florida. And he takes his time with his patients, which has not been my experience elsewhere. Jessica and Shelby over in the Spravato clinic are so helpful and easy to talk to. And, again, they spend actual time with patients. I have nothing bad to say about Cornerstone. My life is vastly improved since I made the switch.”
“My provider is Dr. Flanagan. He is the best! I've gone through a few providers previously and none are like him. He takes his time, talks to me and listens. He also explains thoroughly the treatment plan and medications.”
“I LOVE this place. They are so caring and compassionate. Nadine Causey, PMHNP is my provider and she is way better than more old psychiatrist. Her solution was having me over medicated. Nadine's approach is less is more and adjust accordingly. I cannot say enough good things about her. You have so much to gain with Nadine on your side. Trust me, she's top notch. You won't be disappointed!”
