Our Approach

Our approach to Plumbing, HVAC and Electrical design is to find solutions using a simple and basic process. Our approach is based on the understanding, needs, capabilities and budget of the Owner and Maintenance Staff. This methodology is thoughtfully determined on an individual basis with regards to each project and owner.

We are able to build relationships with each specific Client and truly understand their needs. Through our experience, we have determined that the “simpler” and “easier” a design concept is, the quicker it is to install. This significantly lowers first cost, ongoing maintenance operation and utility costs. System solutions that require less trouble shooting are more efficient and more cost effective for the Owner.

Our approach is “simple” but that doesn’t mean that we aren’t on track with current industry trends new and innovative solutions such as day lighting control, energy recovery, solar water heating, rainwater catchment to name a few. These solutions have been only utilized when they provide both benefit and value to the owner. Our approach has consistently proven to be well received by owners and the occupants of the building.

It is with deep regret that we announce John R. Pelletier, 64, passed away on August 29, 2021, at his home in Portsmouth, VA. with his loving wife by his side. He was born on August 29, 1957, to the late Josephine and Albert Pelletier. Left to cherish his memory is his wife of 24 years, Sherri Pelletier.

John had been with Hickman-Ambrose for the last 32 years. John cultivated many relationships with clients and co-workers that would describe him as a friend and mentor. He enjoyed helping people and can best be described as a true gentleman.

John was a valued member of the living history community through the National Park Service, Civic Groups and Schools where he was passionate about teaching. He was a member and past Commander of the Norfolk County Grays Camp 1549 Sons of Confederate Veterans (SCV) and participated in living history as a Confederate Surgeon. He traveled for years lecturing on Civil War era Medicine, especially Elwood Plantation, a former Confederate Hospital sight. He attended and participated in local historical events such as Civil War Days in Chesapeake and Suffolk.

John enjoyed many hobbies including being a part of a Ford Mustang car club and building miniature models. He also really enjoyed spending time with his Belgian Shepard dogs. 

John was a man of integrity, strength, humor, and grace. Although he was an only child, he was a chosen Brother, Uncle, and friend to so many. He will be dearly missed.
