Meet our co-founders

Paws on the Hill is a pet-care company founded by sister and brother Darlene Hajduk and Donald Tropp over 10 years ago. Based in Washington, D.C., Paws on the Hill provides a wide range of pet-care services, including cat sitting and dog walking, to pet owners in the area. They have a team of pet sitters who provide concierge-level care, ensuring that each pet’s individual needs are met.

Both Darlene and Donald are lifelong animal lovers and have a passion for providing high-quality care for pets. They started Paws on the Hill because they saw a need for reliable and trustworthy pet-care services in the Washington, D.C. area. They understand that pets are members of the family, and they want to ensure that they are well taken care of when their owners are away. Paws on the Hill is fully insured and bonded, ensuring that our clients have peace of mind when they entrust us with the care of their beloved pets. 

At Paws on the Hill, the team is dedicated to providing the best possible care for their clients’ pets. They take the responsibility of caring for pets very seriously and pride themselves on their reliability and professionalism. With Paws on the Hill, pet owners can be confident that their furry family members are in good hands.
