Dr. Manohar Singh, DVM

I wanted to be a veterinarian from a young age. I spent school days in the city and vacations on my grandparent’s farm where I was happiest looking after and caring for the farm animals, milking cows, playing fetch with their Doberman Rocky.

I earned my Doctor of Veterinary Medicine and Master’s in Veterinary Medicine from the University of Punjab, India, and a Graduate Certificate from Purdue University, Indiana. As my education and passion kept on growing for the treatment of small animals, I joined the San Dimas Animal Hospital team in 2003 and have had the opportunity to serve our furry friends and their parents since then.

In 2004 I became the proud owner of San Dimas Animal Hospital. My team and I have been committed to serving the small animal community, through listening, team & client education, preventative care, dental care, internal medicine, soft tissue and orthopedic surgery.

My wife, Arvinder, and I are the proud parents of two children, Aneal and Anisha, who are now in university on their own adventures. I enjoy traveling, playing badminton, taking walks and spending time with family, friends and with the SDAH team.


Dr. Ravneet Dhillon, DVM

Since I was young, I knew I wanted to combine the challenge of medicine with my love for animals.
I grew up close to San Dimas in a veterinary family, watching uncles and cousins in the professional field. My interest deepened while working as a technician at San Dimas Animal Hospital, leading me to earn my Doctor of Veterinary Medicine from Kansas State in 2022.

I strive to meet each patient’s individual needs. I have a keen interest in surgeries, especially the creativity of different procedures and new or improved techniques.
In my free time, I enjoy playing the guitar and piano and cycling through our neighboring communities.


Dr. Samantha Delgado, DVM

I have always loved animals, big & small. Animals have always brought me joy and comfort throughout my life, & I knew since I was young that I wanted to dedicate my life to helping them. My love of animals mixed with my passion for medicine led me to the path of Veterinary Medicine.

I grew up in Glendora & started volunteering at San Dimas Animal Hospital in 2015 while working on my degree in Animal Science at CalPoly Pomona. I was eventually hired at SDAH & worked my way up from Kennel Attendant to Veterinary Assistant and then Veterinary Technician. I earned my Doctorate of Veterinary Medicine from Ross University & completed my clinical year at Purdue University.

I believe that each animal is unique & I focus on helping each patient on an individual basis. I have an interest in traditional and holistic medicine as well as surgery and like to keep my caseload diverse.

I enjoy spending time with my husband, David, and our Australian cattle dog, Hiccup. In my spare time I find joy in baking, gardening, spending time in nature, and traveling.
