Sureet Ghuman, DVM

Dr. Ghuman graduated from veterinary school at Iowa State University. She was raised in Las Vegas and could not wait to move back home to care for the animals in her community (and to escape the harsh Midwest winter!). She’s felt an immense connection to animals since her childhood and has a passion for their welfare. Dr. Ghuman enjoys the variety and excitement of general practice, but especially appreciates having the ability to develop strong relationships with her clients and patients. Her particular interests include dermatology, cardiology, and senior pet wellness.

She has a papillon named Scooby who has been with her for more than half her life! Together, they have traveled the country in pursuit of higher education, but both are happy to finally be home! In her free time, she enjoys reading, baking, and the occasional Netflix binge watching!
