“I’ve been nicknamed the “nicest gentlemen in the west” because I treat my patients like family. I take a very personal approach to each couple or individual I meet. No patient is alike, and neither is their treatment. With customization for every patient, attention to detail is crucial.
I want every patient to have the best quality of care, and I do everything I can to create a successful outcome.

I am not just a physician. I’m also an artist (a musician, poet, and writer). This side of me allows me to treat my patients more with my heart. I like to think it's a combination of heart, mind, and skill."

On behalf of our team and laboratory, we are 100% committed to our patients and are available 24/7 to care for them according to each individual’s needs, which sometimes means showing up to the lab very early in the morning (~6 am) or the middle of the night (~1 am).
