What People Say About Dr. Ratan Ahuja

The new Orange City office is a major improvement and much more comfortable than the old. Wait times seem less and definitely more comfortable. These small but vital issues are crucial in eliminating stress, especially for heart patients. I am not an easy person to develop a trust due to my PTSD after military service. Dr. Ahuja always makes me comfortable, explains things clearly, and answers my questions. I feel comfortable and confident in his care. Dr. Ahuja’s staff is accommodating, and I wish to give a little extra recognition to Ms. Prabha (? spelling) at the front counter for her added attention to challenges when organizing appointments and resolving administrative issues. Also, Jennifer for her outstanding ability as a technician and keeping me in my happy place.

I would rate Dr. Ahuja very high on his expertise and his patient concerns. Always a pleasure to see him. He operated on me and I can't say enough about his level of care. His staff are first rate and even though I only come once a year they know me by my first name and treat me with respect and the utmost courtesy.

"Very pleased" is the description which depicts my immense satisfaction with Dr. Ahuja. A heart cath confirmed a blocked circumflex artery. Dr. Ahjua explained in detail the surgical placement of two stents in the artery. The stents were run through the groin into the artery and up to the heart region. It was painless. Dr. Ahuja was present in follow-up to to assure all was seamless and problem free. I was in skillful, competent and knowledgeable hands throughout. Strongly recommend: A+
