Dr. Hadash, DVM


From the small farm town of Weimar, Texas, Dr. Hadash grew up working on a ranch surrounded by dogs, cattle, and horses. He always had an affinity for his four-legged friends. ‘Growing up in a small town, there was never a doubt in my mind that I wanted to pursue a career in veterinary medicine. Although many people told me I wouldn’t make it into vet school, I was determined to achieve my dream of becoming a veterinarian.’

Upon graduation from high school, he started basic courses at Wharton Jr. College. Shortly after, Dr. Hadash transferred to Texas A&M University and earned his Doctor of Veterinary Medicine Degree in 1981. He then began his life’s work as a veterinarian at Triangle Animal Clinic.

Triangle Animal Clinic has been in Dr. Hadash’s heart since earning his DVM Degree. Other than working as a technician at Wharton Vet Clinic and in the Biomedical Sciences Lab during college, he has always been at Triangle Animal Clinic. A few years after graduation, he became a supervising veterinarian at Triangle Animal Clinic. In 1985 he became the sole owner of the clinic. Dr. Hadash’s passion lies in the care he provides for both his patients and clients and has cared for multiple generations of pet owners.

Dr. Hadash says the best thing about working at Triangle Animal Clinic is the good background in veterinary medicine he learned from his friend and mentor, Dr. McIlhaney, who founded Triangle Animal Clinic in 1973. He also enjoys owning the clinic and working for himself.

Dr. Hadash shares his life with his loving wife, three children, three dogs, three cats, and a hundred head of cattle. In his spare time, Dr. Hadash enjoys spending time with his family, outdoor grilling, fishing, outdoor activities that include wildlife, nature, and working with his cattle.
