In 1902, Jack returned to Yountakah where he stayed until 1904. The following year he moved to Englewood Country Club where he was the pro for over seventeen years, living in Phelps Avenue.

Hobens had an outstanding record in the US. Open, finishing fourteenth in 1902, and never out of the top eleven in his next eight appearances. His best chance came in 1907, when he led the championship after the third round, only to close with a 12 over-par 85, finishing seven strokes behind winner Alex Ross brother of the well known course designer Donald Ross.

During that tournament at the Philadelphia Cricket Club, he holed his tee shot at the 147 yard, 10th to register the first US. Open hole-in-one. On 22nd June 1906, Hobens entered the Western Open at Homewood C.C in Illinois, when he finished second to Alex Smith from Carnoustie. Hobens took the early 36-hole lead by shooting 154, but Smith shot 75-74 on the final day to capture the title by three strokes. Willie Anderson and Fred McLeod from North Berwick tied for third place.

In September 1908 Jack Hobens won the Metropolitan Open Championship at Baltusrol, New Jersey. That year for the first time all golf professionals in America were invited to enter the tournament, but in reality most of the competitors came from Boston, New York and Philadelphia. Played over two days with a foursome match on the third day. The field included the other North Berwick caddies Tom Anderson (Montclair), George Turnbull (Washington) and the Thomson brothers, James R Thomson (Merion) and Robert M. Thomson (Knollwood).

At that tournament Jack Hobens and Jock Hutchison shot 71 to set a new course record. At the sixth, Hobens played his second over the trees and laid the ball dead on the green, he also holed his mashie shot for a two at the ninth. Jack held on to win the tournament by a single stroke from Alex Campbell (originally from Musselburgh). Hobens collected the $150 first prize and received another $75 in special prizes. This was the highlight of a stunning playing career and from that day Hobens was always associated with the 1908 Metropolitan Open Championship.

In 1909, Jack hosted the US. Open, played at Englewood Golf Club where he was the professional. It was the practice during the week of the US. Open, to hold garden parties, vaudeville shows, firework displays, evening dances and competitions for the professionals organised by the host Club. On Tuesday a unique pro-am featuring mixed partners took place and a best ball foursome game on Wednesday. Miss Julia R. Mix teamed up with Jack Hobens to win the competition on 162. In the best ball match, Mix and Hobens carded a 69 and Willie Anderson and his partner finished second.

That year, Willie Anderson's younger brother Tom Anderson Jr. entered the Championship from the Montclair Golf Club, and finished in 8th place. The winner was George Sargent , while Willie Anderson finished 4th; Jack Hobens 6th, and the defending champion Fred McLeod finished in 13th place. In 1910 Jack Hobens was elected president of the Eastern Professional Golfers Association which was a forerunner to the PGA of America. In the qualifying rounds for the 1913 US Open at Brookline, Jack partnered Ted Ray and the New York Times reported that when they both launched towering tee shots over and past the elbow of the dogleg on Polo Field the crowd erupted in appreciation. The two men walked off down the first fairway trailed by the largest-gallery of the day - over a thousand people including the writer Bernard Darwin.

On 17th January 1916, Rodman Wanamaker, a keen amateur golfer and heir to the Wanamaker department store fortune (now Macy's), held a meeting at the Taplow Club, in the Hotel Martinique on the corner of Broadway and West 32nd Steet in New York City for the purpose of forming the Professional Golfers Association of America. The luncheon was attended by several leading amateurs and 35 professionals, known as the 'Charter Members', including Jack Hobens and James R. Thomson from North Berwick. Their aim was to advance the standing of the club professional, caddies and greenkeepers in the United States.

Jack was one of seven chosen to make up the original 'Organising Committee' and one of three professionals who wrote the PGA's first constitution and by-laws. The committee met several times at Hotel Martinique in Manhattan before the constitution, fashioned on the British PGA was approved on 10th April 1916 when their first business was conducted. Wanamakers sponsored the first PGA Championship in 1916 when Jack Hobens reached the last sixteen. Cornishman Jim Barnes defeated the former St Andrews caddie, Jock Hutchison by one hole, to lift the Wanamaker Trophy. In July 1917, the PGA organised the biggest War Relief Tournament ever. Played over a week on four courses, Englewood, Baltusrol, Siwanoy and Garden City. It included matches between a Homebred team versus a Scottish team and an English team. In the Scottish team (photographed below) were Fred McLeod and Jack Hobens.

In the winter of 1916 Jack Hobens was employed in the golf department on the top floor of Wanamaker's store in New York. John D. Dunn (from North Berwick) was head of the 18 teaching staff, and the list of instructors read like a who's who of golfers from the period and the facility was the largest in the city.

Jack's brother William Hobens emigrated in 1903 and joined Jack at Younkatah Country Club, Nutley, NJ. In 1911 his younger brother Robert 'Bob' Hoben was the first pro to be appointed to Shawnee Country Club, Shawnee-On-Delaware, PA. In 1923, they were joined by their 23 year old nephew Francis 'Frank' Hobens who was pro at Quetonset C.C, Westbrook, Connecticut (1925-26), then Massena C.C, New York (1927-30), before being appointed golf instructor at the New York Athletic Club. He lived with his wife Nellie from Illinois, daughter Margaret and son Thomas at 4024 Glenwood Road, Brooklyn, NY.

Jack Hobens was pro at Yountakah (1900); Glen Ridge (1901); Yountakah (1902-04); Englewood Country Club (1905-22); Knickerbocker (1927-1941) all in New Jersey, and Huntingdon Valley Country Club in Pennsylvania (1923-26). He was elected a Life Member of the PGA of America and one of his clubs is on display in the PGA headquarters along with 25 others clubs from the founding fathers.

Jack Hobens died on 26th March 1944, aged 64 years at his home at 134, West Hudson Avenue, Englewood, NJ. He had five daughters and at the time of his death three sons serving in the Marine Corps in WW2. In 2005, Jack Hobens grandson Brook wrote." He was a lovely man who came from nothing and made quite a success for himself and his family. When he died, he left each of his children a house and a portfolio of Blue Chips that provided nicely for my grandmother for some thirty years of widowhood. My Mom was the eldest of their eight children."
